Chassis

The Cisco Catalyst 6807-XL switch chassis has seven horizontal slots, of which five are module slots and two are supervisor engine slots.

Supervisor Engine

The switch supports these Supervisor Engine 2T models:

- VS-S2T-10G

- VS-S2T-10G-XL

Note

The term supervisor engine is used to refer to Supervisor Engine 2T.

The following requirements apply to the supervisor engines installed on the switch:

- Install a 3000 W or higher-capacity power supply.

- Install supervisor engines only in slot 3 or 4.

If the slots are not occupied by supervisor engines, you can install service modules. However, you cannot install Ethernet modules in slot 3 and 4. Check your software release notes for any restrictions on the type of module that can be installed.

- In systems with redundant supervisor engines, both the supervisor engines must be of the same model and have the same daughter card configurations.

- Each supervisor engine must have the resources to run the switch on its own, which means that all the supervisor engine resources are duplicated. Identical supervisor engine memory configurations are recommended, but are not required, as long as the supervisor engine with the smaller memory configuration is sufficient to run the configured features of the switch. Additionally, each supervisor engine must have its own flash device and console port connections.

The uplink ports are fully functional on all redundant supervisor engine models when they are in the standby mode. For more information, see the Catalyst 6500 Series Switch Module Installation Note and the "Supervisor Engine 2T" section in the Catalyst 6500 Series Switch Supervisor Engine Guide.

For more information, see the Catalyst 6500 Ethernet Module Installation Guide.

Fan Tray

The switch supports a single front-serviceable and hot-swappable fan tray with nine individual fans. The fan tray is responsible for cooling the entire chassis and interfacing with environmental monitors to trigger alarms when conditions exceed thresholds.

The fan tray supports:

- Model number C6807-XL-FAN.

- A maximum cooling capacity of 850 CFM[1] (120 CFM per slot). At this capacity, the fan tray can cool seven 800 W modules.

- Four variable-speed operating modes between 3,000 and 6,000 RPM [2] for each fan.

- Up to three fan failures. The fans that are working increase RPM or CFM.

- Online Insertion and Removal (OIR) for a minimum of 120 seconds (depending on the ambient temperature).

Note

Individual fans are not field-replaceable units (FRUs). You must replace the fan tray.

[1] Cubic feet per minute.

[2] Revolutions per minute.

Power Supply Module

The switch supports one to four field-replaceable power supply modules (PSMs) labeled 1 to 4, with a single system On/Off switch.

The PSM supports:

- Model number C6800-XL-3KW-AC.

- Redundant and combined configuration modes. The redundant mode is the default and recommended mode.

- Only AC input.

- 3000 W when powered with 240VAC, and 1300 W when powered with 120VAC.

- Only single-phase source AC. Source AC can be out of phase between multiple power supplies or multiple AC-power plugs on the same power supply because all AC power supply inputs are isolated.

This table describes the available power supply configuration modes:

PSM Configuration Modes

Redundant Mode (n+1)

Combined Mode (n+0)

Description

The system operates on two to four PSMs. This includes a reserve PSM that is available in case of a failure. The system power supply configuration is n[1] PSMs +1 redundant PSM.

The system operates on one to four power supplies. The power available to the system is the sum of power outputs of all the PSMs in the chassis.

Operating capacity

With two PSMs (1+1):

- One PSM operates at 100 percent capacity.

- The +1 redundant PSM operates at 0 percent of its capacity.

With three PSMs (2+1):

- One PSM operates at 100 percent capacity.

- One PSM operates at 90 percent of its capacity.

- The +1 redundant PSM operates at 0 percent of its capacity.

With four PSMs (3+1):

- One PSM operates at 100 percent capacity.

- Two PSMs operate at 90 percent of their capacity (90 percent each).

- The +1 redundant PSM operates at 0 percent of its capacity.

All available PSMs operate at 100 percent capacity.

In case of failure

The +1 redundant PSM takes over and operates at 90 percent capacity.

There is no redundant power supply in this mode. The PSMs that are still operational continue to work. If they are not able to handle the load, the necessary number of modules are shut down. The number of modules that will be shut down depends on the amount of combined power the operational PSMs are able to provide.

For example, if you have installed two PSMs, they supply 6000 W, which can power a fully loaded chassis. But if one PSM fails, the power provided drops down to 3000 W, which causes some modules to shut down.

Recommendation

This is the recommended and default mode.

If you have a fully loaded chassis, we recommend that you install at least three PSMs operating in a redundant mode (2+1).

Although available, we recommend that you do not use this mode. If you are implementing this mode, we recommend at least two PSMs (2+0) operating in the combined mode.

[1] Total number of operational PSMs

The PSMs provide 3000 W when powered with 240 VAC, and 1300 W when powered with 120 VAC. In systems where power supply modules provide different wattage, you may not have true redundancy. If the PSM with the higher wattage fails, the PSM with the lower wattage might not be able to handle the entire load by itself and system power management will shut down devices.

Note

When shutting down devices, depending on how much power saving is needed, the system powers down modules in a descending order, starting with the highest-numbered slot. Slots containing supervisor engines are bypassed and are not powered down (Power is automatically reserved for supervisor engine slots). This shutdown order is fixed and cannot be changed.

You can change the configuration of the power supplies to redundant or combined at any time. If you switch from a redundant to a combined configuration, all the available PSMs are enabled (even a PSM that was disabled because it was of a lower wattage ). If you change from a combined to a redundant configuration, all the available PSMs are initially enabled, and if they are of the same wattage, they remain enabled. If they are of different wattage, a syslog message appears and the lower wattage supply is disabled.

Power Entry Module

The switch supports one to four AC power entry modules (PEMs) labeled AC1 to AC4. The four PEMs connect to the four corresponding PSMs (Labeled 1 to 4), for example, AC1 connects to 1 and so on.

The AC input voltage from the PEM is transmitted to the backplane, which then conducts it to the PSM. The power supply module generates the necessary amount of power.

Power Supply Converter

The switch supports two redundant, field-replaceable 52 V converters labeled PSC1 and PSC2.

The PSC converts the 52 V supplied by the PSM to 3.3 V and conducts it to the backplane. The clock module, VTT modules, and module slots (line cards) require 3.3 V.

The PSC supports:

- Model number C6807-X-3.3V.

- Redundancy—The PSCs share power when both are installed. If one PSC fails, the chassis will still be operational.

LEDs

Use the switch LEDs to monitor switch activity and performance.

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

Site Requirements

Planning a proper location for the switch and layout of the equipment rack or wiring closet is essential for successful system operation. These sections describe some of the basic site requirements that you should be aware of as you prepare to install your switch, including the following:

- Environmental factors can adversely affect the performance and longevity of your system.

- Install the switch in an enclosed, secure area, ensuring that only qualified personnel have access to the switch and control of the environment.

- Equipment that is placed too closely together or that is inadequately ventilated may cause system over-temperature conditions, leading to premature component failure.

- Poor equipment placement can make chassis panels inaccessible and difficult to maintain.

- The switch requires a dry, clean, well-ventilated, and air-conditioned environment.

- To ensure normal operation, maintain ambient airflow. If the airflow is blocked or restricted, or if the intake air is too warm, an over-temperature condition may occur. The switch environmental monitor may then shut down the system to protect the system components.

- Multiple switches can be rack mounted with little or no clearance above and below the chassis. However, when mounting a switch in a rack with other equipment, or when placing it on the floor near other equipment, ensure that the exhaust from other equipment does not blow into the air intake vent of the switch chassis.

Temperature

Temperature extremes may cause a system to operate at reduced efficiency and cause a variety of problems, including premature aging and failure of chips, and failure of mechanical devices. Extreme temperature fluctuations may also cause chips to become loose in their sockets. Observe the following guidelines:

- Ensure that the system is operating in an environment no colder than 50°F (10°C) or hotter than 95°F (35°C).

- Ensure that the chassis has adequate ventilation.

- Do not place the chassis within a closed-in wall unit or on top of cloth, which can act as insulation.

- Do not place the chassis where it will receive direct sunlight, particularly in the afternoon.

- Do not place the chassis next to a heat source of any kind, including heating vents.

- Adequate ventilation is particularly important at high altitudes. Make sure that all the slots and openings on the system remain unobstructed, especially the fan vent on the chassis.

- Clean the installation site at regular intervals to avoid buildup of dust and debris, which may cause a system to overheat.

- If the system has been exposed to abnormally cold temperatures, allow a 2-hour warm-up period to bring it to normal operating temperature before turning it on.

Failure to observe these guidelines may damage the chassis' internal components.

Air Flow

The switch is designed to be installed in an environment where there is a sufficient volume of air available to cool the supervisor engines, modules, and power supplies. If there are any constraints with regard to the free flow of air through the chassis, or if the ambient air temperature is elevated, the switch environmental monitor may then shut down the system to protect the system components.

To maintain proper air circulation through the switch chassis, we recommend that you maintain a minimum space of 6 inches (15 cm) between a wall and the chassis air intake or a wall and the chassis hot air exhaust. In situations where the switch chassis are installed in adjacent racks, you should allow a minimum space of 12 inches (30.5 cm) between the air intake of one chassis and the hot air exhaust of another chassis. Failure to maintain adequate spacing between chassis may cause the switch chassis that is drawing in the hot exhaust air to overheat and fail.

If you are installing your switch in an enclosed or partially enclosed rack, we strongly recommend that you verify that your site meets the following guidelines:

- Verify that there is a minimum of 6 inches (15 cm) of clearance between the sides of the rack and both the chassis air intake grill and the chassis air exhaust grill.

- Verify that the ambient air temperature within the enclosed or partially enclosed rack is within the chassis operating temperature limits. After installing the chassis in the rack, power up the chassis and allow the chassis temperature to stabilize (approximately 2 hours). Measure the ambient air temperature at the chassis air intake grill and at the chassis air exhaust grill by positioning an external temperature probe approximately 1 inch (2.5 cm) away from the grills, in line with the chassis slot occupied by a supervisor engine.

- If the ambient intake air temperature is less than 104°F (40°C), the rack meets the intake air temperature criterion.

- If the ambient intake air temperature exceeds 104°F (40°C), the system might experience minor temperature alarms and is in danger of overheating.

- If the ambient intake air temperature equals or is greater than 131°F (55°C), the system will experience a major temperature alarm and shut down.

- Verify that the enclosed or partially enclosed rack allows an adequate flow of air through the switch chassis as follows:

- If the difference between the measured intake air temperature and the exhaust air temperature does not exceed 10°C, there is sufficient airflow in the rack.

- If the difference in air temperature exceeds 10°C, there is insufficient airflow to cool the chassis.

Note

Determine the 10°C temperature difference between the intake and the exhaust by taking measurements using external digital temperature probes. Do not use the chassis internal temperature sensors to measure the temperature difference.

- Plan ahead. A switch that is currently installed in an enclosed or partially enclosed rack might meet ambient air temperature and air flow requirements at present. However, if you add more chassis to the rack or more modules to a chassis in the rack, the additional heat generated might cause the ambient air temperature within the rack to exceed 104°F (40°C) and may cause minor alarms.

Humidity

High-humidity conditions may cause moisture to enter the system, and cause corrosion of internal components and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size. Extreme moisture buildup inside the system may result in electrical short circuit, which may cause serious damage to the system. Each system is rated to operate at 5 to 90 percent relative humidity, with a humidity gradation of 10 percent per hour. In storage, a system can withstand 5 to 95 percent relative humidity. Buildings in which climate is controlled by air-conditioning in the warmer months and by heat during the colder months usually maintain an acceptable level of humidity for system equipment. However, if a system is located in an unusually humid location, a dehumidifier should be used to maintain the humidity within an acceptable range.

Altitude

Operating a system at high altitude (low pressure) reduces the efficiency of forced and convection cooling and may result in electrical problems related to arcing and corona effects. This condition may also cause sealed components with internal pressure, such as electrolytic capacitors, to fail or perform at reduced efficiency. Each system is rated to operate at altitudes from -50 to 6500 feet (-16 to 1981 meters) and can be stored at altitudes of -50 to 35,000 feet (-16 to 10,668 meters).

Dust and Particles

Fans cool power supplies and system components by drawing in room-temperature air and exhausting heated air out through various openings in the chassis. However, fans also ingest dust and other particles, causing contaminant buildup in the system and increased internal chassis temperature. A clean operating environment can greatly reduce the negative effects of dust and other particles, which act as insulators and interfere with the mechanical components in the system. The standards listed below provide guidelines for acceptable working environments and acceptable levels of suspended particulate matter:

- National Electrical Manufacturers Association (NEMA) Type 1

- International Electrotechnical Commission (IEC) IP-20

Corrosion

Corrosion of system connectors is a gradual process that may eventually lead to intermittent failures of electrical circuits. The oil from a person’s fingers or prolonged exposure to high temperature or humidity may corrode the gold-plated edge connectors and pin connectors on various components in the system. To prevent corrosion, avoid touching contacts on boards and cards, and protect the system from extreme temperatures and moist, salty environments.

EMI and Radio Frequency Interference

EMI and radio frequency interference (RFI) from a system can adversely affect devices such as radio and television (TV) receivers operating near the system. Radio frequencies emanating from a system can also interfere with cordless and low-power telephones. Conversely, RFI from high-power telephones can cause spurious characters to appear on the system monitor. RFI is defined as any EMI with a frequency above 10 kilohertz (kHz). This type of interference can travel from the system to other devices through the power cable and power source, or through the air in the form of transmitted radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and RFI emitted by computing equipment. Each system meets these FCC regulations. To reduce the possibility of EMI and RFI, follow these guidelines:

- Always operate the system with the chassis covers installed.

- Ensure that all chassis slots are covered by a metal filler bracket and that an unused power supply bay has a metal cover plate installed.

- Ensure that the screws on all peripheral cable connectors are securely fastened to their corresponding connectors on the back of the chassis.

- Always use shielded cables with metal connector shells for attaching peripherals to the system.

When wires are run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires. This fact has two implications for the construction of plant wiring:

- Bad wiring practice can result in radio interference emanating from the plant wiring.

- Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the chassis, and even create an electrical hazard by conducting power surges through lines into equipment.

Note

To predict and provide a remedy for strong EMI, consult experts in RFI.

If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.

Caution

Category 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the dielectric properties of the materials used in their construction. Always ground the cables (especially in new cable runs) to a suitable and safe earth ground before connecting them to the module.

If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding.

Power Source Interruptions

Systems are especially sensitive to variations in voltage supplied by the AC power source. Overvoltage, undervoltage, and transients (or spikes) can erase data from memory or even cause components to fail. To protect against these types of problems, power cables should always be properly grounded. Also, place the system on a dedicated power circuit (rather than sharing a circuit with other heavy electrical equipment). In general, do not allow the system to share a circuit with any of the following:

- Copy machines

- Air conditioners

- Vacuum cleaners

- Space heaters

- Power tools

- Teletype machines

- Laser printers

- Facsimile machines

- Any other motorized equipment

Besides these appliances, the greatest threats to a system's power supply are surges or blackouts that are caused by electrical storms. Whenever possible, turn off the system and peripherals, if any, and unplug them from their power sources during thunderstorms. If a blackout occurs—even a temporary one—while the system is turned on, turn off the system immediately and disconnect it from the electrical outlet. Leaving the system on may cause problems when the power is restored; all other appliances left on in the area may create large voltage spikes that may damage the system.

System Grounding

You must install a system ground as part of the chassis installation process. Chassis installations that rely only on the AC third-prong ground are insufficient to adequately ground the systems.

Proper grounding practices ensure that the buildings and the installed equipment within them have low-impedance connections and low-voltage differentials between chassis. When you install a system ground, you reduce or prevent shock hazards, chances of equipment damage due to transients, and the potential for data corruption.

Without proper and complete system grounding, you run the risk of increased component damage due to ESD. Additionally, you have a greatly increased chance of data corruption, system lockup, and frequent system reboot situations by not using a system ground.

Caution

Installations that rely solely on system grounding that uses only an AC third-prong ground run a substantially greater risk of equipment problems and data corruption than those installations that use both the AC third-prong ground and a properly installed system ground.

The following table lists some general grounding practice guidelines.

Grounding Practice Guidelines

Environment

Electromagnetic Noise Severity Level

Grounding Recommendations

Commercial building is subjected to direct lightning strikes.

For example, some places in the United States, such as Florida, are prone to more lightning strikes than other areas.

All lightning protection devices must be installed in strict accordance with manufacturer recommendations. Conductors carrying lightning current should be spaced away from power and data lines in accordance with applicable recommendations and codes. Best grounding practices must be closely followed.

Commercial building is located in an area where lightning storms occur frequently, but is not prone to direct lightning strikes.

High

Best grounding practices must be closely followed.

Commercial building contains a mix of information technology equipment and industrial equipment, such as welding.

Medium to High

Best grounding practices must be closely followed.

Existing commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment. This installation has a history of malfunction due to electromagnetic noise.

Best grounding practices must be closely followed. Determine source and cause of noise if possible, and mitigate as closely as possible at the noise source or reduce coupling from the noise source to the victim equipment.

New commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment.

Low

Best grounding practices should be followed as closely as possible. Electromagnetic noise problems are not anticipated, but installing a best-practice grounding system in a new building is often the least expensive route, and the best way to plan for the future.

Existing commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment.

Low

Best grounding practices should be followed as much as possible. Electromagnetic noise problems are not anticipated, but installing a best-practice grounding system is always recommended.

Note

In all situations, grounding practices must comply with Section 250 of the National Electric Code (NEC) requirements or local laws and regulations. A 6 AWG grounding wire is preferred from the chassis to the rack ground or directly to the common bonding network (CBN). The equipment rack should also be connected to the CBN with a 6 AWG grounding wire.

Note

In installations where FXS modules are installed, supplemental grounding is required.

Note

Always ensure that all of the modules are completely installed and that the captive installation screws are fully tightened. In addition, ensure that all the I/O cables and power cords are properly seated. These practices are normal installation practices and must be followed in all installations.

Caution

Category 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the dielectric properties of the materials used in their construction. Always ground the cables (especially in new cable runs) to a suitable and safe earth ground before connecting them to the module.

Maintaining Safety with Electricity

When working on electrical equipment, follow these guidelines:

- Do not work alone if potentially hazardous conditions exist anywhere in your work space.

- Never assume that power is disconnected from a circuit; always check the circuit before working on it.

- Look carefully for possible hazards in your work area, such as damp floors, ungrounded power extension cables, frayed or damaged power cords, and missing safety grounds.

- If an electrical accident occurs, proceed as follows:

- Use extreme caution; do not become a victim yourself.

- Disconnect power from the system.

- If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.

- Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

- Use the product within its marked electrical ratings and product usage instructions.

- Install the product in compliance with local and national electrical codes.

- If any of the following conditions occur, contact the Cisco Technical Assistance Center:

- The power cable or plug is damaged.

- An object has fallen into the product.

- The product has been exposed to water or other liquids.

- The product has been dropped or shows signs of damage.

- The product does not operate correctly when you follow the operating instructions.

- Use the correct external power source. Operate the product only from the type of power source indicated on the electrical ratings label. If you are not sure of the type of power source required, consult the Cisco Technical Assistance Center or a local electrician.

- Use approved power cables only. You have been provided with one or more power cables with your chassis power supply that are intended for use in your country, based on the shipping location. Should you need to purchase additional power cables, ensure that they are rated for the product and for the voltage and current marked on the product’s electrical ratings label. The voltage and current rating of the power cable should be greater than the ratings marked on the label.

- To help prevent electrical shock, plug all the power cables into properly grounded electrical outlets. These power cables are equipped with three-prong plugs to ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a power cable.

- Observe power strip ratings. Make sure that the total current rating of all products that are plugged into the power strip does not exceed 80 percent of the power strip rating.

- Do not modify power cables or plugs yourself. Consult with a licensed electrician or your power company for site modifications. Always follow your local and national wiring codes.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage may occur when modules or other FRUs are improperly handled, and result in intermittent or complete failure of the modules or FRUs. Modules consist of printed circuit boards that are fixed in metal carriers. EMI shielding and connectors are integral components of a carrier. Although the metal carrier helps to protect the board from ESD, always use an ESD-grounding strap when handling modules. To prevent ESD damage, follow these guidelines:

- Always use an ESD wrist strap and ensure that it has maximum contact with bare skin. ESD grounding straps are available with banana plugs, metal spring clips, or alligator clips. The chassis is equipped with a banana plug connector (identified by the ground symbol next to the connector) on the front panel.

- If you choose to use the disposable ESD wrist strap supplied with most FRUs or an ESD wrist strap equipped with an alligator clip, you must attach the system ground lug to the chassis in order to provide a proper grounding point for the ESD wrist strap.

Power Requirements

Power supplies installed on the switch chassis must be AC input only. When preparing your site for switch installation, adhere to these requirements:

- In systems configured with more than one power supply, connect each of the power supplies to a separate input power source. If you fail to do this, your system might be susceptible to total power failure due to a fault in the external wiring or a tripped circuit breaker.

- To prevent loss of input power, be sure that the total maximum load on each source circuit is within the current ratings of the wiring and breakers.

- In some systems, you may decide to use an uninterrupted power supply (UPS) to protect against power failures at your site. Be aware when selecting a UPS that some UPS models that use ferroresonant technology may become unstable when operating with the switch power supplies that use power factor correction. This may cause the output voltage waveform to the switch to become distorted, resulting in an undervoltage situation in the system.

- The AC-input power supply has a detachable power cord.

- Each chassis power supply should have a separate, dedicated branch circuit.

- North America—the 1300 W and 3000 W power supplies require a 20 A circuit.

- International—Circuits should be sized according to local and national codes.

- If you are using a 200 or 240 VAC power source in North America, the circuit must be protected by a two-pole circuit breaker.

- The source AC outlet must be within 6 feet (1.8 meters) of the system, and should be easily accessible.

- The AC power receptacles used to plug in the chassis must be the grounding type. The grounding conductors that connect to the receptacles should connect to protective earth ground at the service equipment level.

Cabling Requirements

When running power and data cables together in overhead cable trays or subfloor cable trays, be aware of the following caution:

Caution

We strongly recommend that power cabling runs and other potential noise sources be located as far away as practical from LAN cabling that terminates on Cisco equipment. In situations where this type of long parallel cable runs exist and cannot be separated by at least 3.3 feet (1 meter), we recommend that you shield these potential noise sources. To avoid interference, the source should be shielded by housing it in a grounded metallic conduit.

Also be aware of the following caution concerning the use of Category 5e and Category 6 Ethernet cables:

Caution

Category 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the dielectric properties of the materials used in their construction. Always ground the cables (especially in new cable runs) to a suitable and safe earth ground before connecting them to the module.

Rack-Mounting Guidelines

The Cisco Catalyst 6807-XL Switch is designed to be installed in both open and enclosed racks. The switch can be installed on 19-inch equipment racks. If you are using a 2-post or 4-post 19-inch standard equipment rack, before rack-mounting the switch, ensure that the equipment rack complies with these guidelines:

- The width of the rack, measured between the two front-mounting rails, must be one of the following measurements:

- 17.5 inches (44.45 cm)

- 17.75 inches (45.09 cm)

- The depth of the rack, measured between the front-mounting and rear-mounting strips, must be at least 17.61 inches (44.72 cms).

- The rack must have sufficient clearance in terms of height and depth, to insert the chassis. The chassis height is 17.5 inches (44.45 cms).

Note

Chassis height is sometimes measured in rack units (RU or just U) where 1 RU or 1 U equals 1.75 inches (44.45 mm). A typical server rack is 42 RU or 42 U in height. The Cisco Catalyst 6807-XL Switch chassis is 10 RU in height.

You can also use a center rack-mount kit for 23-inch, telco-style racks. The kit is not included in the accessory kit, but can be ordered separately (Part number C6800-XL-CNTR-MNT=). Installation instructions are included with the kit.

Caution

If the rack is on wheels, ensure that the brakes are engaged and that the rack is stabilized.

Warning

Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over. Statement 1048

Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

- This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

- When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

- If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006

Note

The chassis are designed to be mounted in equipment racks that meet ANSI/EIA 310-D and ETS 300-119 standards.

Note

To maintain proper air circulation through the Catalyst switch chassis, we recommend that you maintain a minimum 6-inch (15-cm) separation between a wall and the chassis air intake or a wall and the chassis air exhaust. You should also allow a minimum separation of 12 inches (30.5 cm) between the hot air exhaust on one chassis and the air intake on another chassis. Failure to maintain adequate air space can cause the chassis to overheat and the system to fail. On Catalyst switch chassis in which the airflow is from front to back, you can place the chassis side-by-side.

What to Do Next

After installing the chassis in its location, complete the installation process by:

1. Connecting the chassis to system ground.

2. Installing and connecting the power supplies to the power source.

3. Connecting the network interface cables to the supervisor engine and modules. This may involve installing transceivers before you attach the network interface cables.

4. Powering up the chassis and verifying the installation.

Establishing System Ground

To attach the grounding lug and cable to the grounding pad, perform these steps

Before You Begin
To connect the system ground, you require the following tools and materials:

- Grounding lug—A two-hole right-angled lug. Supports up to 6 AWG wire. Supplied as part of accessory kit.

- Grounding screws—Two M4 x 8 mm (metric) pan-head screws. Supplied as part of the accessory kit.

- Grounding wire—Not supplied as part of accessory kit. The grounding wire should be sized according to local and national installation requirements. Depending on the power supply and system, a 12 to 6 AWG copper conductor is required for U.S. installations. Commercially available 6-AWG wire is recommended. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

- No. 1 Phillips screwdriver.

- Crimping tool to crimp the grounding wire to the grounding lug.

- Wire-stripping tool to remove the insulation from the grounding wire.

Procedure

Step 1

Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the grounding wire.

Step 2

Insert the stripped end of the grounding wire into the open end of the right-angled grounding lug.

Step 3

Crimp the grounding wire in the barrel of the grounding lug. Verify that the ground wire is securely attached to the ground lug.

Step 4

Secure the grounding lug to the system ground connector with two M4 screws. Ensure that the grounding lug and the grounding wire do not interfere with other switch hardware or rack equipment.

Step 5

Prepare the other end of the grounding wire, and connect it to an appropriate grounding point in your site to ensure adequate earth ground for the switch.

Attaching an ESD Strap

After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:

Procedure

Step 1

Attach the ESD wrist strap to bare skin as follows:

1. If you are using the ESD wrist strap supplied with the FRUs, open the wrist strap package and unwrap the ESD wrist strap. Place the black conductive loop over your wrist and tighten the strap such that it touches your bare skin well.

2. If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove the ESD wrist strap. Locate the end of the wrist strap that attaches to your body and secure it to your bare skin.

Step 2

Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal spot (unpainted surface) on the rack. We recommend that you touch the clip to an unpainted rack rail so that any built-up static charge is then safely dissipated to the entire rack.

Step 3

Attach either the spring clip or the alligator clip to the ground lug screw as follows:

1. If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws open, position the spring clip to one side of the system ground lug screw head, and slide the spring clip over the lug screw head so that the spring clip jaws close behind the lug screw head.

Note:
The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or the lug barrel.

2. If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip directly over the head of the system ground lug screw or to the system ground lug barrel.

When handling modules, follow these guidelines:

- Handle carriers using the available handles or edges only; avoid touching the printed circuit boards or connectors.

- Place a removed component boardside up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.

- Never attempt to remove the printed circuit board from the metal carrier.

Caution:
For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).

Verifying the Switch Chassis Installation

To verify the switch chassis installation, perform these steps:

Procedure

Step 1

Verify that the ejector levers of each module are fully closed (parallel to the faceplate) to ensure that the supervisor engine and all the switching modules are fully seated in the backplane connectors.

Step 2

Check the captive installation screws of each module, power supply, and power supply converter. Tighten loose captive installation screws.

Step 3

Verify that all empty module slots have blank faceplates installed properly. The blank faceplates optimize the air flow through the chassis and contain EMI.

Warning:
Blank faceplates and cover panels serve three important functions— They prevent exposure to hazardous voltages and currents inside the chassis; they contain EMI that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system until all cards, face plates, front covers, and rear covers are in place. Statement 1029

Step 4

Turn on the power supply switches to power up the system. During the power-up sequence, the system performs a series of bootup diagnostic tests.

What to Do Next
Additional system diagnostic tests are available. These tests allow you to perform a complete sanity check on the system prior to inserting the system into your network and to monitor the health of the system while the system is running.

Tip

When prestaging systems in a nonproduction environment, we recommend that you run all the diagnostic tests, including the disruptive tests, to prescreen the systems for failures, if any.

- Online Diagnostics

Online Diagnostics

The Cisco Catalyst 6807-XL switches running Cisco IOS have many levels of online diagnostic capabilities. The online diagnostics are divided into the following categories:

- Bootup—Bootup diagnostics automatically run during bootup, module OIR, or switchover to a backup supervisor engine.

- Background health—Monitoring diagnostic tests are continuously run by the system to monitor system health.

- On-demand online diagnostics—On-demand online diagnostics can be used to run any test from the CLI. You can also run on-demand online diagnostics to perform a sanity check on the system hardware. Some of these tests are disruptive and will impact traffic flow. You must follow the on-demand diagnostic guidelines exactly to avoid false failures.

- Scheduled diagnostics—Scheduled diagnostics can be used to run any of the above tests at user-designated intervals.

Connecting the Supervisor Engine Console Port

The console port on the supervisor engine allows you to perform the following functions:

- Configure the switch from the CLI.

- Monitor network statistics and errors.

- Configure SNMP agent parameters.

- Download software updates to the switch, or distribute software images residing in flash memory to attached devices.

Note

You have to order the necessary cable and adapters to connect a terminal or modem to the console port.

To connect a terminal to the console port and then connect a modem to the console port using the cable and adapters, follow these steps:

Connect to the port using the RJ-45-to-RJ-45 cable and the RJ-45-to-DB-25 DTE adapter or the RJ-45-to-DB-9 DTE adapter (labeled Terminal).

Step 2

Check the corresponding terminal documentation to determine the baud rate.
The baud rate of the terminal must match the default baud rate (9600 baud) of the console port. Set up the terminal as follows:

- 9600 baud

- 8 data bits

- No parity

- 2 stop bits

Step 3

Connect to the port using the RJ-45-to-RJ-45 rollover cable and the RJ-45-to-DB-25 DCE adapter (labeled Modem).
The console port mode switch should be in the IN position (factory default).

Step 4

Position the cable in the cable guide (if installed). Make sure there are no sharp bends in the cable.

Installing Transceivers and Module Connectors

Some Ethernet modules require that pluggable transceivers be installed in the module port sockets. These transceivers are normally shipped separately from the module and must be installed after the module is installed in the chassis slot.

For detailed instructions about installing the various kinds of pluggable transceivers and module connectors, see the following:

Chapter 4. Removing and Replacing FRUs

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

- Online Insertion and Removal

- Removing and Installing Power Supplies

- Removing and Installing the Fan Tray

- Removing and Installing the Power Supply Converter

Online Insertion and Removal

The online insertion and removal (OIR) feature allows you to remove and replace modules while the system is online. You can shut down the modules before removal and restart them after insertion, without causing other software or interfaces to shut down.

Note

Do not remove or install more than one module at a time. After you remove or install a module, check the module LEDs before continuing.

When a module is removed or installed, the switch stops processing traffic for the module and scans the system for a configuration change. Each interface type is verified against the system configuration, and then the system runs diagnostics on the new module. There is no disruption of normal operation during module insertion or removal.

The switch can bring up only an identical replacement module online. To support the OIR of an identical module, the module configuration is not removed from the running-config file when you remove a module.

If the replacement module is different from the removed module, you must configure it before the switch can bring it online.

Layer 2 MAC addresses are stored in an EEPROM, which allows modules to be replaced online without requiring the system to update switching tables and data structures. Regardless of the types of modules installed, the Layer 2 MAC addresses do not change unless you replace the supervisor engine. If you do replace the supervisor engine, the Layer 2 addresses of all the ports change to those specified in the address allocator on the new supervisor engine.

Removing and Installing Power Supplies

This section describes how to remove and install PSMs.

Note

- The PSMs installed in the switch chassis should be AC input only.

- The PSM is designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system.

The following table lists specifications for the 3000 W AC input power supply:

3000 W AC-Input Power Supply Specifications

Specification

Description

AC-input type

Autoranging input with power factor correction.
Note:   Power factor correction is a standard feature on AC-input power supplies. Power factor correction reduces the reactive component in the source AC current, allowing higher power factors (typically 99 percent or better) and lower harmonic current components.

AC-input voltage

Low-line (120 VAC nominal)—90 VAC (min) to 132 VAC (max)

High-line (230 VAC nominal)—170 VAC (min) to 264 VAC (max)

AC-input current

16 A @ 240 VAC (3000 W output)

16 A @ 120 VAC (1300 W output)

AC-input frequency

50/60 Hz (nominal) (±3% for full range)

Branch circuit requirement

Each chassis power supply should have its own dedicated, fused-branch circuit:

- North America—20 A.

- International—Circuits sized to local and national codes.

- All AC power supply inputs are fully isolated:

- Source AC can be out of phase between multiple power supplies in the same chassis, which means that PS1 can be operating from phase A and PS2 can be operating from phase B.

- For high-line operation, the power supply operates with the hot conductor wired to a source AC phase and the neutral conductor wired either to ground or to another source AC phase as long as the net input voltage is in the range of 170 to 264 VAC.

- Source AC can be out of phase between AC inputs on power supplies that are equipped with multiple AC inputs, which means that power cord 1 can be plugged into phase A and power cord 2 can be plugged into phase B.

Module Connectors

This section provides brief descriptions of the module connectors that the switch supports.

- RJ-45 Connector

- SC Connector

- LC Connector

- MTP-12 Connector

RJ-45 Connector

The RJ-45 connector is used to connect a Category 3, Category 5, Category 5e, or Category 6 foil twisted-pair or unshielded twisted-pair cable from the external network to the module interface connector.

RJ-45 Interface Cable Connector

Caution

Category 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the dielectric properties of the materials used in their construction. Always ground the cables (especially in new cable runs) to a suitable and safe earth ground before connecting them to the module.

Caution

To comply with GR-1089 intrabuilding and lightning immunity requirements, you must use a foil twisted-pair (FTP) cable that is properly grounded at both ends.

SC Connector

The SC connector is used to connect fiber-optic module ports or transceivers with the external SMF or MMF network.

Warning

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

Note

Make sure that the optical connectors are clean before making the connections. Contaminated connectors can damage the fiber and cause data errors.

SC Fiber-Optic Connector

Always insert the network connector completely into the socket. A secure connection is especially important when you are establishing a connection between a module and a long-distance (1.24 miles) (2 km) network, or a module and a suspected highly attenuated network. If the link LED does not light up, try removing the network cable plug and reinserting it firmly into the module socket. It is possible that dirt or skin oils have accumulated on the plug faceplate (around the optical-fiber openings), generating significant attenuation and reducing the optical power levels below threshold levels so that a link cannot be established.

Caution

Use extreme care when removing or installing connectors so that you do not damage the connector housing or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.

LC Connector

The LC fiber optic connector is a small form-factor fiber-optic connector that provides high-density fiber connectivity. The LC connector can be used with either MMF cable or SMF cable. The LC connector uses a latching clip mechanism that is similar to the one used on the RJ-45 copper connector.

Warning

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

Note

Make sure that the optical connectors are clean before making the connections. Contaminated connectors can damage the fiber and cause data errors.

LC Fiber-Optic Connector

MTP-12 Connector

The MTP connector is 12-fiber optical connector with a footprint similar to the SC simplex connector. The MTP connector conforms to the TIA/EIA-604-5 intermateability standard.

Each port must match the wave-length specifications on the other end of the cable, and the cable must not exceed the stipulated cable length. Copper 1000BASE-T SFP module transceivers use standard four twisted-pair, Category 5 cable at lengths up to 328 feet (100 meters).

Console Cables

The supervisor engine's front-panel console ports allow you to connect a terminal or modem to the console port.

- You can connect a terminal to the console port using one of these options:

- The RJ45 console port—Uses an 8-pin RJ-45 connector, and has built-in DTE capability.

If the RJ-45 port does not have built-in DTE capability, use the RJ-45-to-RJ-45 rollover cable and DTE adapter, such as the DB-9 adapter. You can use the 6-ft DB9 Female-to-RJ45 console cable (to be ordered separately; Part Number: 72-3383-01).
DB9 Female-to-RJ45 Cable

- The USB console port—Uses a USB Type A to 5-pin mini Type B cable (to be ordered separately; Part Number: 37-1090-01).
USB Type A-to-USB 5-Pin Mini-Type B Cable

- You can connect a modem to the console port by using the RJ-45-to-RJ-45 roll over cable and DTE adapter.

Identifying a Rollover Cable

You can identify a rollover cable by comparing the two ends of the cable. Holding the cables side by side, with the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. If your cable was purchased from Cisco, pin 1 will be white on one connector, and pin 8 will be white on the other. (A rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5.)

Mode-Conditioning Patch Cord

When using the long-wavelength and long-haul (LX and LH) GBIC with 62.5-micron diameter multimode fiber (MMF), you must install a mode-conditioning patch cord (Cisco product number CAB-GELX-625 or equivalent) between the GBIC and the MMF cable on both the transmit and receive ends of the link.

A mode-conditioning patch cord is required for 1000BASE-LX and LH applications over FDDI-grade, OM1, and OM2 fiber-cable types. Mode-conditioning patch cords should not be used for applications over OM3 fiber cable (laser-optimized fiber cable). For more information about mode-conditioning patch cords, see the Use of Mode Conditioning Patch Cables in Gigabit Ethernet and 10 Gigabit Ethernet Laser-Based Transmissions bulletin available on Cisco.com.

Note

We recommend that you use the LX and LH GBIC and MMF with the patch cord for short link distances of 33 to 328 feet (10 to 100 meters) because not using the patch could result in an elevated bit error rate (BER).

The patch cord is required to comply with IEEE standards. IEEE found that link distances could not be met with certain types of fiber-optic cable due to a problem in the center of some fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center by using the patch cord. At the output of the patch cord, the LX and LH GBIC complies with the IEEE 802.3z standard for 1000BASE-LX.

Installing the Patch Cord

Warning

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

To install the patch cord, perform these steps:

Procedure

Step 1

Plug the end of the patch cord labeled To Equipment into the GBIC. See Figure 1.

Step 2

Plug the end labeled To Cable Plant into the patch panel. See Figure 1.
The patch cord is 9.8-feet (3-meters) long and has duplex SC male connectors at each end.

Patch Cord Installation

Differential Mode Delay

When an unconditioned laser source designed for operation on an SMF cable is directly coupled with an MMF cable, differential mode delay (DMD) might occur. DMD may degrade the modal bandwidth of the fiber-optic cable. This degradation causes a decrease in the link span (the distance between the transmitter and the receiver) that can be reliably supported.

The Gigabit Ethernet specification (IEEE 802.3z) outlines parameters for Ethernet communications at a gigabit-per-second rate. The specification offers a higher-speed version of Ethernet for backbone and server connectivity using existing deployed MMF cable by defining the use of laser-based optical components to propagate data over MMF cable.

Lasers function at the baud rates and longer distances required for Gigabit Ethernet. The 802.3z Gigabit Ethernet Task Force has identified the DMD condition that occurs with particular combinations of lasers and MMF cable. The results create an additional element of jitter that can limit the reach of Gigabit Ethernet over MMF cable.

With DMD, a single laser light pulse excites a few modes equally within an MMF cable. These modes, or light pathways, then follow two or more different paths. These paths might have different lengths and transmission delays as the light travels through the cable. With DMD, a distinct pulse propagating down the cable no longer remains a distinct pulse, or in extreme cases, might become two independent pulses. Strings of pulses may interfere with each other making it difficult to recover data.

DMD does not occur in all deployed fibers; it occurs with certain combinations of worst-case fibers and worst-case transceivers. Gigabit Ethernet experiences this problem because of its very high baud rate and its long MMF cable lengths. SMF cable and copper cable are not affected by DMD.

MMF cable has been tested for use only with LED sources. LEDs can create an overfilled launch condition within the fiber-optic cable. The overfilled launch condition describes the way LED transmitters couple light into the fiber-optic cable in a broad spread of modes. Similar to a light bulb radiating light into a dark room, the generated light that shines in multiple directions can overfill the existing cable space and excite a large number of modes.

LED Transmission Compared to Laser Transmission

Lasers launch light in a more concentrated fashion. A laser transmitter couples light into only a fraction of the existing modes or optical pathways present in the fiber-optic cable. See Figure 1

The solution is to condition the laser light launched from the source (transmitter) so that it spreads the light evenly across the diameter of the fiber-optic cable making the launch look more like an LED source to the cable. The objective is to scramble the modes of light to distribute the power more equally in all the modes and prevent the light from being concentrated in just a few modes.

An unconditioned launch, in the worst case, might concentrate all of its light in the center of the fiber-optic cable, exiting only two or more modes equally.

A significant variation in the amount of DMD is produced from one MMF cable to the next. No reasonable test can be performed to survey an installed cable plant to assess the effect of DMD. Therefore, you must use the mode-conditioning patch cords for all uplink modules using MMF when the link span exceeds 984 feet (300 meters).

For link spans less than 984 feet (300 meters), you can omit the patch cord. We recommend that you do no use the LX and LH GBIC and MMF without the patch cord for very short link distances of 33 to 328 feet (10 to 100 meters) because it may result in an elevated BER.

Cleaning the Fiber-Optic Connectors

Fiber-optic connectors are used to connect two fibers together. When these connectors are used in a communications system, proper connection becomes a critical factor.

Fiber-optic cable connectors can be damaged by improper cleaning and connection procedures. Dirty or damaged fiber-optic connectors can result in communication that is not repeatable or is inaccurate.

Fiber-optic connectors differ from electrical or microwave connectors. In a fiber-optic system, light is transmitted through an extremely small fiber core. Because fiber cores are often 62.5 microns or less in diameter, and dust particles range from a tenth of a micron to several microns in diameter, dust and any contamination at the end of the fiber core can degrade the performance of the connector interface where the two cores meet. The connector must be precisely aligned, and the connector interface must be absolutely free of trapped foreign material.

Connector loss or insertion loss is a critical performance characteristic of a fiber-optic connector. Return loss is also an important factor. Return loss specifies the amount of reflected light; the lower the reflection, the better the connection. The best physical contact connectors have return losses greater than -40 dB, although -20 to -30 dB is more common.

The connection quality depends on two factors: the type of connector and the proper cleaning and connection techniques. Dirty fiber connectors are a common source of light loss. Keep the connectors clean at all times, and keep the dust covers installed when the connectors are not in use.

Before installing any type of cable or connector, use a lint-free alcohol pad from a cleaning kit to clean the ferrule, the protective white tube around the fiber, and the end-face surface of the fiber.

As a general rule, whenever there is a significant, unexplained loss of light, clean the connectors.

- Guidelines

- How to Clean the Fiber-Optic Connectors

Guidelines

The connectors used inside the system are cleaned by the manufacturer and connected to the adapters in a proper manner. The operation of the system should be error free if the customer provides clean connectors on the application side and follows these guidelines:

- Cleans the connectors using either a CLETOP cassette cleaner (Type A for SC connectors and Type B for MT-RJ connectors) or lens tissues before connecting to the adapters; uses pure alcohol to remove contamination.

- Does not clean the inside of the connector adapters.

- Does not use force or quick movements when connecting the fiber-optic connectors in the adapters.

- Covers the connectors and adapters to keep the inside of the adapters or the surface of the connectors from getting dirty when not using the connectors or while cleaning the chassis.

How to Clean the Fiber-Optic Connectors

Caution

Use extreme care when removing or installing connectors so that you do not damage the connector housing or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.

To clean optical connectors, use a CLETOP cassette cleaner (type A for SC connectors or type B for MT-RJ connectors) and follow the product directions.

Warning

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

Procedure

Step 1

Use a lint-free tissue soaked in 99 percent pure isopropyl alcohol to gently wipe the faceplate. Wait five seconds for the surfaces to dry, and repeat.

Step 2

Remove any residual dust from the faceplate with clean, dry, oil-free compressed air.

Step 3

Use a magnifying glass or inspection microscope to inspect the ferrule at an angle. Do not look directly into the aperture. Repeat the process if any contamination is detected.

- Solving Problems at the System Component Level

- Identifying Startup Problems

- Troubleshooting the Power Supply Module

- Troubleshooting the Fan Tray

- Contacting Cisco Customer Service

- Finding Serial Numbers

Getting Started

When the initial system startup is complete, verify the following:

- Power supplies are supplying power to the system.

- The fan tray assembly is operating.

- System software boots successfully.

If one or more of the above conditions are not met, use the procedures described in this chapter to isolate and, if possible, resolve the problem. If all of the above conditions are met, and the hardware installation is complete, refer to your software release notes for hardware support information and software caveats.

Solving Problems at the System Component Level

The key to success when troubleshooting the system is to isolate the problem to a specific system component. The first step is to compare what the system is doing to what it should be doing. Because a startup problem can usually be attributed to a single component, it is more efficient to isolate the problem to a subsystem rather than troubleshoot each separate component in the system.

The switch consists of these subsystems:

- Power supplies

- Fan tray assembly

The chassis fan tray assembly should operate whenever system power is on. You should see the FAN LED turn green and hear the fan tray assembly operating. A red FAN LED indicates that one or more fans in the fan tray assembly is not operating. You should immediately contact a Customer Service representative if the fan tray assembly is not functioning properly. There are no installation adjustments that you can make if the fan tray assembly does not function properly at initial startup.

Identifying Startup Problems

LEDs indicate all system states in the startup sequence. By checking the LEDs, you can determine when and where the system failed in the startup sequence.

Procedure

Step 1

Turn on the power supplies. You should immediately hear the system fan tray assembly begin to operate.

- If you do not hear the fans operating, see the Troubleshooting the Power Supply Module section.

- If you determine that the power supplies are functioning normally and that the fan tray assembly is faulty, contact a customer service representative.

- If the fan tray assembly does not function properly at initial startup, there are no installation adjustments that you can make. Troubleshooting the Fan Tray section.

Step 2

If the startup information and system banner do not display at startup, verify that the terminal is set correctly and that it is connected properly to the console port.

Troubleshooting the Power Supply Module

If the INPUT OK LED does not light up after you turn on the power switch, follow these steps to isolate a power subsystem problem:

Procedure

Step 1

Verify that the INPUT OK LED on the PSM is green.

1. If the IN LED is green, the AC source is good and the power supply is functional.

2. If the IN LED is off, ensure that the PSM is flush with the back of the chassis. Turn off the power switch, tighten the captive installation screw, and then turn on the power switch.

3. If the IN LED remains off, there might be a problem with the AC source or the power cord.

4. Turn off the power to the switch, connect the power cord to another power source if one is available, and turn on the power.

5. If the IN LED is green, the problem is the first power source.

6. If the IN LED fails to light up after you connect the power supply to a new power source, replace the power cord, and turn on the switch.

7. If the IN LED then lights up, return the first power cord for replacement.

If this unit has more than one power cord, repeat Step 1 (and all the substeps) for each PSM.

For information about PSM LEDs, see Power Supply Module LEDs.

Step 2

If the INPUT OK LED still fails to light up when the switch is connected to a different power source with a new power cord, the PSM is probably faulty. If a second PSM is available, install it in the second power supply bay, and contact a Cisco customer service representative for further instructions.

Step 3

Verify that you have installed the power cord in the correct PEM. Each PSM and corresponding PEM is numbered.

Step 4

Repeat Step 1, Step 2 , and Step 3 for all the PSMs that you have installed.

If you are unable to resolve the problem, or if you have determined that either a power supply or a backplane connector is faulty, contact a Cisco customer service representative for instructions.

Troubleshooting the Fan Tray

To isolate a fan tray problem, follow these steps:

Procedure

Step 1

Verify that the FAN LED on the fan tray is green.
If the FAN LED is not green, see Solving Problems at the System Component Level to determine whether or not the power subsystem is functioning properly.

For information about fan tray LEDs, see Fan Tray LED.

Step 2

Check to determine if the FAN LED is red. If the FAN LED is red, the fan tray is not seated in the backplane or has malfunctioned. Perform the following tasks:

1. To ensure that the fan tray is seated properly, remove the fan tray, and reinstall it. See Removing and Installing the Fan Tray.

2. Restart the system.

3. If the FAN LED is still red, the system detects one or more fan failures. Contact a Cisco customer service representative for instructions.

Rack-Mounting the Chassis

Warning

Two people are required to lift the chassis. To prevent injury, keep your back straight and lift with your legs, not your back. Statement 164

Tip

We recommend that you have a third person to assist in this procedure.

To install the switch chassis in the equipment rack, perform these steps:

Before You Begin

- Read the Rack-Mounting Guidelines.

- Install the rack-mount shelf kit. See Installing the Rack-Mount Shelf Kit.

Procedure

Step 1

With a person standing at each side of the chassis, insert one hand into the handhold groove and the other hand near the back of the chassis for balance. Slowly lift the chassis. Avoid sudden twists or moves to prevent injury.

Step 2

Rest the back end of the chassis on the edges of the rack-mount shelf kit rails and carefully slide the chassis fully into the rack.

Step 3

Fan Tray

The switch supports a single front-serviceable and hot-swappable fan tray with nine individual fans. The fan tray is responsible for cooling the entire chassis and interfacing with environmental monitors to trigger alarms when conditions exceed thresholds.

The fan tray supports:

- Model number C6807-XL-FAN.

- A maximum cooling capacity of 850 CFM[1] (120 CFM per slot). At this capacity, the fan tray can cool seven 800 W modules.

- Four variable-speed operating modes between 3,000 and 6,000 RPM [2] for each fan.

- Up to three fan failures. The fans that are working increase RPM or CFM.

- Online Insertion and Removal (OIR) for a minimum of 120 seconds (depending on the ambient temperature).

Note

Individual fans are not field-replaceable units (FRUs). You must replace the fan tray.

Air Flow

The switch is designed to be installed in an environment where there is a sufficient volume of air available to cool the supervisor engines, modules, and power supplies. If there are any constraints with regard to the free flow of air through the chassis, or if the ambient air temperature is elevated, the switch environmental monitor may then shut down the system to protect the system components.

To maintain proper air circulation through the switch chassis, we recommend that you maintain a minimum space of 6 inches (15 cm) between a wall and the chassis air intake or a wall and the chassis hot air exhaust. In situations where the switch chassis are installed in adjacent racks, you should allow a minimum space of 12 inches (30.5 cm) between the air intake of one chassis and the hot air exhaust of another chassis. Failure to maintain adequate spacing between chassis may cause the switch chassis that is drawing in the hot exhaust air to overheat and fail.

If you are installing your switch in an enclosed or partially enclosed rack, we strongly recommend that you verify that your site meets the following guidelines:

- Verify that there is a minimum of 6 inches (15 cm) of clearance between the sides of the rack and both the chassis air intake grill and the chassis air exhaust grill.

- Verify that the ambient air temperature within the enclosed or partially enclosed rack is within the chassis operating temperature limits. After installing the chassis in the rack, power up the chassis and allow the chassis temperature to stabilize (approximately 2 hours). Measure the ambient air temperature at the chassis air intake grill and at the chassis air exhaust grill by positioning an external temperature probe approximately 1 inch (2.5 cm) away from the grills, in line with the chassis slot occupied by a supervisor engine.

- If the ambient intake air temperature is less than 104°F (40°C), the rack meets the intake air temperature criterion.

- If the ambient intake air temperature exceeds 104°F (40°C), the system might experience minor temperature alarms and is in danger of overheating.

- If the ambient intake air temperature equals or is greater than 131°F (55°C), the system will experience a major temperature alarm and shut down.

- Verify that the enclosed or partially enclosed rack allows an adequate flow of air through the switch chassis as follows:

- If the difference between the measured intake air temperature and the exhaust air temperature does not exceed 10°C, there is sufficient airflow in the rack.

- If the difference in air temperature exceeds 10°C, there is insufficient airflow to cool the chassis.

Note

Determine the 10°C temperature difference between the intake and the exhaust by taking measurements using external digital temperature probes. Do not use the chassis internal temperature sensors to measure the temperature difference.

- Plan ahead. A switch that is currently installed in an enclosed or partially enclosed rack might meet ambient air temperature and air flow requirements at present. However, if you add more chassis to the rack or more modules to a chassis in the rack, the additional heat generated might cause the ambient air temperature within the rack to exceed 104°F (40°C) and may cause minor alarms.

3000 W Power Supply AC Power Cords

Power Supply Module

The switch supports one to four field-replaceable power supply modules (PSMs) labeled 1 to 4, with a single system On/Off switch.

The PSM supports:

- Model number C6800-XL-3KW-AC.

- Redundant and combined configuration modes. The redundant mode is the default and recommended mode.

- Only AC input.

- 3000 W when powered with 240VAC, and 1300 W when powered with 120VAC.

- Only single-phase source AC. Source AC can be out of phase between multiple power supplies or multiple AC-power plugs on the same power supply because all AC power supply inputs are isolated.

This table describes the available power supply configuration modes:

PSM Configuration Modes

Redundant Mode (n+1)

Combined Mode (n+0)

Description

The system operates on two to four PSMs. This includes a reserve PSM that is available in case of a failure. The system power supply configuration is n[1] PSMs +1 redundant PSM.

The system operates on one to four power supplies. The power available to the system is the sum of power outputs of all the PSMs in the chassis.

Operating capacity

With two PSMs (1+1):

- One PSM operates at 100 percent capacity.

- The +1 redundant PSM operates at 0 percent of its capacity.

With three PSMs (2+1):

- One PSM operates at 100 percent capacity.

- One PSM operates at 90 percent of its capacity.

- The +1 redundant PSM operates at 0 percent of its capacity.

With four PSMs (3+1):

- One PSM operates at 100 percent capacity.

- Two PSMs operate at 90 percent of their capacity (90 percent each).

- The +1 redundant PSM operates at 0 percent of its capacity.

All available PSMs operate at 100 percent capacity.

In case of failure

The +1 redundant PSM takes over and operates at 90 percent capacity.

There is no redundant power supply in this mode. The PSMs that are still operational continue to work. If they are not able to handle the load, the necessary number of modules are shut down. The number of modules that will be shut down depends on the amount of combined power the operational PSMs are able to provide.

For example, if you have installed two PSMs, they supply 6000 W, which can power a fully loaded chassis. But if one PSM fails, the power provided drops down to 3000 W, which causes some modules to shut down.

Recommendation

This is the recommended and default mode.

If you have a fully loaded chassis, we recommend that you install at least three PSMs operating in a redundant mode (2+1).

Although available, we recommend that you do not use this mode. If you are implementing this mode, we recommend at least two PSMs (2+0) operating in the combined mode.

[1] Total number of operational PSMs

The PSMs provide 3000 W when powered with 240 VAC, and 1300 W when powered with 120 VAC. In systems where power supply modules provide different wattage, you may not have true redundancy. If the PSM with the higher wattage fails, the PSM with the lower wattage might not be able to handle the entire load by itself and system power management will shut down devices.

Note

When shutting down devices, depending on how much power saving is needed, the system powers down modules in a descending order, starting with the highest-numbered slot. Slots containing supervisor engines are bypassed and are not powered down (Power is automatically reserved for supervisor engine slots). This shutdown order is fixed and cannot be changed.

You can change the configuration of the power supplies to redundant or combined at any time. If you switch from a redundant to a combined configuration, all the available PSMs are enabled (even a PSM that was disabled because it was of a lower wattage ). If you change from a combined to a redundant configuration, all the available PSMs are initially enabled, and if they are of the same wattage, they remain enabled. If they are of different wattage, a syslog message appears and the lower wattage supply is disabled.

Connecting the Supervisor Engine Console Port

The console port on the supervisor engine allows you to perform the following functions:

- Configure the switch from the CLI.

- Monitor network statistics and errors.

- Configure SNMP agent parameters.

- Download software updates to the switch, or distribute software images residing in flash memory to attached devices.

Note

You have to order the necessary cable and adapters to connect a terminal or modem to the console port.

To connect a terminal to the console port and then connect a modem to the console port using the cable and adapters, follow these steps:

Procedure

Step 1

Connect to the port using the RJ-45-to-RJ-45 cable and the RJ-45-to-DB-25 DTE adapter or the RJ-45-to-DB-9 DTE adapter (labeled Terminal).

Step 2

Check the corresponding terminal documentation to determine the baud rate.
The baud rate of the terminal must match the default baud rate (9600 baud) of the console port. Set up the terminal as follows:

- 9600 baud

- 8 data bits

- No parity

- 2 stop bits

Step 3

Connect to the port using the RJ-45-to-RJ-45 rollover cable and the RJ-45-to-DB-25 DCE adapter (labeled Modem).
The console port mode switch should be in the IN position (factory default).

Step 4

Position the cable in the cable guide (if installed). Make sure there are no sharp bends in the cable.

Supervisor Engine

The switch supports these Supervisor Engine 2T models:

- VS-S2T-10G

- VS-S2T-10G-XL

Note

The term supervisor engine is used to refer to Supervisor Engine 2T.

The following requirements apply to the supervisor engines installed on the switch:

- Install a 3000 W or higher-capacity power supply.

- Install supervisor engines only in slot 3 or 4.

If the slots are not occupied by supervisor engines, you can install service modules. However, you cannot install Ethernet modules in slot 3 and 4. Check your software release notes for any restrictions on the type of module that can be installed.

- In systems with redundant supervisor engines, both the supervisor engines must be of the same model and have the same daughter card configurations.

- Each supervisor engine must have the resources to run the switch on its own, which means that all the supervisor engine resources are duplicated. Identical supervisor engine memory configurations are recommended, but are not required, as long as the supervisor engine with the smaller memory configuration is sufficient to run the configured features of the switch. Additionally, each supervisor engine must have its own flash device and console port connections.

The uplink ports are fully functional on all redundant supervisor engine models when they are in the standby mode. For more information, see the Catalyst 6500 Series Switch Module Installation Note and the "Supervisor Engine 2T" section in the Catalyst 6500 Series Switch Supervisor Engine Guide.

Establishing System Ground

To attach the grounding lug and cable to the grounding pad, perform these steps

Before You Begin
To connect the system ground, you require the following tools and materials:

- Grounding lug—A two-hole right-angled lug. Supports up to 6 AWG wire. Supplied as part of accessory kit.

- Grounding screws—Two M4 x 8 mm (metric) pan-head screws. Supplied as part of the accessory kit.

- Grounding wire—Not supplied as part of accessory kit. The grounding wire should be sized according to local and national installation requirements. Depending on the power supply and system, a 12 to 6 AWG copper conductor is required for U.S. installations. Commercially available 6-AWG wire is recommended. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

- No. 1 Phillips screwdriver.

- Crimping tool to crimp the grounding wire to the grounding lug.

- Wire-stripping tool to remove the insulation from the grounding wire.

Procedure

Step 1

Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the grounding wire.

Step 2

Insert the stripped end of the grounding wire into the open end of the right-angled grounding lug.

Step 3

Crimp the grounding wire in the barrel of the grounding lug. Verify that the ground wire is securely attached to the ground lug.

Step 4

Secure the grounding lug to the system ground connector with two M4 screws. Ensure that the grounding lug and the grounding wire do not interfere with other switch hardware or rack equipment.

Preventing Electrostatic Discharge Damage

Attaching an ESD Strap

After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:

Procedure

Step 1

Attach the ESD wrist strap to bare skin as follows:

1. If you are using the ESD wrist strap supplied with the FRUs, open the wrist strap package and unwrap the ESD wrist strap. Place the black conductive loop over your wrist and tighten the strap such that it touches your bare skin well.

2. If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove the ESD wrist strap. Locate the end of the wrist strap that attaches to your body and secure it to your bare skin.

Step 2

Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal spot (unpainted surface) on the rack. We recommend that you touch the clip to an unpainted rack rail so that any built-up static charge is then safely dissipated to the entire rack.

Step 3

Attach either the spring clip or the alligator clip to the ground lug screw as follows:

1. If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws open, position the spring clip to one side of the system ground lug screw head, and slide the spring clip over the lug screw head so that the spring clip jaws close behind the lug screw head.

Note:
The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or the lug barrel.

2. If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip directly over the head of the system ground lug screw or to the system ground lug barrel.

When handling modules, follow these guidelines:

- Handle carriers using the available handles or edges only; avoid touching the printed circuit boards or connectors.

- Place a removed component boardside up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.

- Never attempt to remove the printed circuit board from the metal carrier.

Caution:
For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).

Preventing Electrostatic Discharge Damage

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage may occur when modules or other FRUs are improperly handled, and result in intermittent or complete failure of the modules or FRUs. Modules consist of printed circuit boards that are fixed in metal carriers. EMI shielding and connectors are integral components of a carrier. Although the metal carrier helps to protect the board from ESD, always use an ESD-grounding strap when handling modules. To prevent ESD damage, follow these guidelines:

- Always use an ESD wrist strap and ensure that it has maximum contact with bare skin. ESD grounding straps are available with banana plugs, metal spring clips, or alligator clips. The chassis is equipped with a banana plug connector (identified by the ground symbol next to the connector) on the front panel.

- If you choose to use the disposable ESD wrist strap supplied with most FRUs or an ESD wrist strap equipped with an alligator clip, you must attach the system ground lug to the chassis in order to provide a proper grounding point for the ESD wrist strap.

Rack-Mounting Guidelines

The Cisco Catalyst 6807-XL Switch is designed to be installed in both open and enclosed racks. The switch can be installed on 19-inch equipment racks. If you are using a 2-post or 4-post 19-inch standard equipment rack, before rack-mounting the switch, ensure that the equipment rack complies with these guidelines:

- The width of the rack, measured between the two front-mounting rails, must be one of the following measurements:

- 17.5 inches (44.45 cm)

- 17.75 inches (45.09 cm)

- The depth of the rack, measured between the front-mounting and rear-mounting strips, must be at least 17.61 inches (44.72 cms).

- The rack must have sufficient clearance in terms of height and depth, to insert the chassis. The chassis height is 17.5 inches (44.45 cms).

Note

Chassis height is sometimes measured in rack units (RU or just U) where 1 RU or 1 U equals 1.75 inches (44.45 mm). A typical server rack is 42 RU or 42 U in height. The Cisco Catalyst 6807-XL Switch chassis is 10 RU in height.

You can also use a center rack-mount kit for 23-inch, telco-style racks. The kit is not included in the accessory kit, but can be ordered separately (Part number C6800-XL-CNTR-MNT=). Installation instructions are included with the kit.

Caution

If the rack is on wheels, ensure that the brakes are engaged and that the rack is stabilized.

Warning

Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over. Statement 1048

Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

- This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

- When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

- If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006

Note

The chassis are designed to be mounted in equipment racks that meet ANSI/EIA 310-D and ETS 300-119 standards.

Note

To maintain proper air circulation through the Catalyst switch chassis, we recommend that you maintain a minimum 6-inch (15-cm) separation between a wall and the chassis air intake or a wall and the chassis air exhaust. You should also allow a minimum separation of 12 inches (30.5 cm) between the hot air exhaust on one chassis and the air intake on another chassis. Failure to maintain adequate air space can cause the chassis to overheat and the system to fail. On Catalyst switch chassis in which the airflow is from front to back, you can place the chassis side-by-side.
