Chapter 2. Preparing the Site

This chapter includes the following sections:

- Humidity Requirements

- Altitude Requirements

- Dust and Particulate Requirements

- Minimizing Electromagnetic and Radio Frequency Interference

- Shock and Vibration Requirements

- Grounding Requirements

- Planning for Power Requirements

- Rack and Cabinet Requirements

- Clearance Requirements

Humidity Requirements

High humidity can cause moisture to seep into the switch. Moisture can cause corrosion of internal components and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size. The switch is rated to operate at 8 to 80 percent relative humidity, with a humidity gradation of 10 percent per hour.

The switch can withstand from 5 to 90 percent relative humidity. Buildings in which the 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 the switch equipment. However, if the switch is located in an unusually humid location, you should use a dehumidifier to maintain the humidity within an acceptable range.

Altitude Requirements

If you operate a switch at a high altitude (low pressure), the efficiency of forced and convection cooling is reduced and can result in electrical problems that are related to arcing and corona effects. This condition can also cause sealed components with internal pressure, such as electrolytic capacitors, to fail or to perform at a reduced efficiency. This switch is rated to operate at altitudes from –500 to 13,123 feet (–152 to 4,000 meters). You can store the switch at altitudes of –1,000 to 30,000 feet (–305 to 9,144 meters).

Dust and Particulate Requirements

Exhaust fans cool power supplies and system fan trays cool switches by drawing in air and exhausting air out through various openings in the chassis. However, fans also ingest dust and other particles, causing contaminant buildup in the switch 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 switch.

Note

If you are using this switch in a nonclean environment, you can order and install an optional air filter. This air filter requires that you also order the optional front door for the chassis.

In addition to regular cleaning, follow these precautions to avoid contamination of your switch:

- Do not permit smoking near the switch.

- Do not permit food or drink near the switch.

Minimizing Electromagnetic and Radio Frequency Interference

Electromagnetic interference (EMI) and radio frequency interference (RFI) from the switch can adversely affect other devices such as radio and television (TV) receivers operating near the switch. Radio frequencies that emanate from the switch can also interfere with cordless and low-power telephones. Conversely, RFI from high-power telephones can cause spurious characters to appear on the switch monitor.

RFI is defined as any EMI with a frequency above 10 kHz. This type of interference can travel from the switch to other devices through the power cable and power source or through the air like transmitted radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and RFI that can be emitted by computing equipment. Each switch meets these FCC regulations.

To reduce the possibility of EMI and RFI, follow these guidelines:

- Cover all open expansion slots with a metal filler.

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

When wires are run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires and cause the following implications:

- Bad wiring 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 prevent strong EMI, you might need to consult experts in radio frequency interference (RFI).

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

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 switches. You may want to consult experts in electrical surge suppression and shielding if you had similar problems in the past.

Shock and Vibration Requirements

The switch has been shock- and vibration-tested for operating ranges, handling, and earthquake standards to Network Equipment Building Standards (NEBS) Zone 4 per GR-63-Core.

Grounding Requirements

The switch is sensitive to variations in voltage supplied by the power sources. Overvoltage, undervoltage, and transients (or spikes) can erase data from the memory or cause components to fail. To protect against these types of problems, ensure that there is an earth-ground connection for the switch. You can connect the grounding pad on the switch either directly to the earth-ground connection or to a fully bonded and grounded rack.

You must provide the grounding cable to make this connection but you can connect the grounding wire to the switch using a grounding lug that ships with the switch. Size the grounding wire to meet local and national installation requirements. Depending on the power supply and system, a 12 AWG to 6 AWG copper conductor is required for U.S. installations (for those installations, we recommend that you use commercially available 6 AWG wire). The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

Note

You automatically ground the AC power supplies when you connect them to a power source, but you cannot ground a 3-kW DC power supply. You must connect the chassis to the facility earth ground.

Planning for Power Requirements

To plan for the power requirements of a switch, you must determine each of the following:

- Power requirements of the switch

- Minimum number of power supplies required to power the switch and its components

- Power mode to use and the number of additional power supplies required for that mode

You must also ensure that the circuit used for the switch is dedicated to the switch to minimize the possibility of circuit failure.

When you know the amount of power that is required for operations (available power) and redundancy (reserve power), you can plan for the required number of input power receptacles with reach of the switch location.

Step 1

Determine the power requirement for the switch by summing the maximum wattage for each installed module (see the following table).

Step 2

Determine the number of power supplies needed for the available power requirement by dividing the power requirement amount (see Step 1) by the output wattage of the power supplies installed in the switch.

Step 3

Select one of the following power modes to determine the number of additional power supplies required for reserve power:

- Combined power—Do not add any power supplies to the number of power supplies calculated for the available power in Step 2. This power mode does not provide power redundancy, so no extra power supplies are needed.

- Power supply redundancy (n+1 redundancy)—Add one power supply (reserve power supply). This form of power redundancy provides a reserve power supply that can replace any active power supply that goes offline.

- Input source redundancy (grid redundancy)—Add enough power supplies (reserve power supplies) to at least equal the total output of the active power supplies (number of power supplies calculated in Step 2). Typically, you would double the number of power supplies. You must plan for a second power source for the reserve power supplies.

- Full redundancy (n+1 and grid redundancy)—Add enough power supplies (reserve power supplies) to at least equal the output of the active power supplies (number of power supplies calculated in Step 2). For power supply (n+1) redundancy, ensure that . For input-source (grid) redundancy, you will probably double the number of power supplies. You must plan for a second power source with at least the same amount of input power for the reserve power supplies. Either one of the reserve power supplies can replace any of the active power supplies.

Step 4

Be sure that the power source circuits are dedicated to the switch and not to other electrical equipment.
For combined power mode (no power redundancy) or power supply (n+1) redundancy, you need only one dedicated circuit. The requirements for each circuit are listed in the following table.

Step 5

Plan the placement of the input power receptacles within reach of the power cables used for each power supply (see the following table for the maximum distances).
Typically, power receptacles are placed on the rack with the switch. If the DC power source is further than allowed by the DC power cables, you can install a power interface unit (PIU) in the rack with the switch and connect that to the power source with other cabling.

Rack and Cabinet Requirements

You can install the following types of racks or cabinets for your switch:

- Standard perforated cabinets

- Solid-walled cabinets with a roof fan tray (bottom to top cooling)

- Standard open four-post Telco racks

- Standard open two-post Telco racks

To correctly install the switch in a cabinet that is located in a hot-aisle/cold-aisle environment, you should fit the cabinet with baffles to prevent exhaust air from recirculating into the chassis air intake.

Work with your cabinet vendors to determine which of their cabinets meet the following requirements or see the Cisco Technical Assistance Center (TAC) for recommendations:

- Use a standard 19-inch, four-post Electronic Industries Alliance (EIA) cabinet or rack with mounting rails that conform to English universal hole spacing per section 1 of the ANSI/EIA-310-D-1992 standard.

- The height of the rack or cabinet must accommodate the 3-RU (5.25 inches or 13.3 cm) height of the switch.

- The depth of a four-post rack must be 24 to 32 inches (61.0 to 81.3 cm) between the front and rear mounting brackets.

- Required clearances between the chassis and the edges of its rack or the interior of its cabinet are as follows:

- 7.5 inches (19.1 cm) between the front of the chassis and the front of the rack or interior of the cabinet (required for cabling).

- 3.0 inches (7.6 cm) between the rear of the chassis and the interior of the cabinet (required for airflow in the cabinet if used).

- No clearance is required between the chassis and the sides of the rack or cabinet (no side airflow).

Additionally, you must consider the following site requirements for the rack:

- Power receptacles must be located within reach of the power cords used with the switch.

- AC power supplies

- Power cords for 3-kW AC power supplies are 8 to 12 feet (2.5 to 3.6 m) long.

- DC power supplies

- Power cords for 3.0-kW DC power supplies are supplied and dimensioned by the customer.

- HVAC/HVDC power supplies

- Power cords for 3.5-kW HVAC/HVDC power supplies are 14 feet (4.26 m) long.

- Clearance required for cables that connect to as many as 200 ports (in addition to the cabling required for other devices in the same rack). These cables must not block access to any removable chassis modules or block airflow into or out of the chassis. Route the cables through the cable management frames on the left and right sides of the chassis.

- Where necessary, have a seismic rating of Network Equipment Building Standards (NEBS) Zone 3 or Zone 4, per GR-63-CORE if required.

- Minimum gross load rating of 2000 lb (907.2 kg) (static load rating) if supporting two switches.

Clearance Requirements

You must provide the chassis with adequate clearance between the chassis and any other rack, device, or structure so that you can properly install the chassis, route cables, provide airflow, and maintain the switch. For the clearances required for an installation of this chassis, see the following figure.

Chapter 3. Installing the Switch Chassis

This chapter includes the following topics:

- Installing a Rack or Cabinet

- Unpacking and Inspecting a New Switch

- Installing the Chassis in a Two-Post Rack

- Installing the Chassis on a Four-Post Rack or Cabinet

- Grounding a Switch Chassis

- Installing Cable Management Frames onto the Chassis

- Attaching the Front Door to the Chassis

Installing a Rack or Cabinet

Before you install the switch, you must install a standard four-post, 19-inch EIA data center rack (or a cabinet that contains such a rack) .

Step 1

Bolt the rack to the concrete subfloor before moving the chassis onto it.
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.

Step 2

If the rack has bonded construction, connect it to the earth ground. This action enables you to easily ground the switch and its components and to ground your electrostatic discharge (ESD) wrist strap to prevent damaging discharges when you handle ungrounded components before installing them.

Step 3

If you need access to the source power at the rack, include either AC power receptacles or a DC power interface unit (PIU) with the amperage required by the switch that you are installing. .
If you are using DC power, be sure that the DC power supply is grounded and that there is direct access to the facility DC power or indirect access though a power interface unit (PIU). You must connect the DC power supply to the earth ground before you connect it to the facility DC power.

Warning:
Take care when connecting units to the supply circuit so that wiring is not overloaded.

Note:
If you are using the combined power mode or power-supply redundancy, you need only one power source. If you are using input-source redundancy or full redundancy, you need two power sources.

Unpacking and Inspecting a New Switch

Before you install a new chassis, you need to unpack and inspect it to be sure that you have all the items that you ordered and verify that the switch was not damaged during shipment. If anything is damaged or missing, contact your customer representative immediately.

Caution

When you handle the chassis or its components, you must follow ESD protocol at all times to prevent ESD damage. This protocol includes but is not limited to wearing an ESD wrist strap that you connect to the earth ground.

Tip

Do not discard the shipping container when you unpack the switch. Flatten the shipping cartons and store them with the pallet used for the system. If you need to move or ship the system in the future, you will need these containers.

Step 1

Compare the shipment to the equipment list that is provided by your customer service representative and verify that you have received all of the ordered items.
The shipment should include boxes for the following:

- System chassis, which includes the following installed components:

- 1 supervisor module

- 1 I/0 module

- 1 fan tray

- 1 to 2 power supply units

- Switch accessory kit

To see a list of what is included in this kit, see Cisco Nexus 7702 Switch Accessory Kit.

- Cable management frames

- Left and right side frames

- Top and bottom hood frames

- M4x14 mm flat-head Phillips screws (4)

Step 3

If you notice any discrepancies or damage, send the following information to your customer service representative by email:

- Invoice number of the shipper (see the packing slip)

- Model and serial number of the missing or damaged unit

- Description of the problem and how it affects the installation

Installing the Chassis in a Two-Post Rack

Before You Begin

- Verify that the chassis shipment is complete and undamaged.

- Verify that a two-post rack is installed and secured to the subfloor.

- 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.

- If there are other devices in the rack, verify that the devices that are heavier than this chassis are installed below where you are going to install the chassis and lighter devices are installed above where you are going to install the chassis.

- Verify that the data center ground is accessible where you are installing the chassis.

Note

Fully loaded, the chassis can weigh up to 81.7 lb (37.05 kg). You can lighten the chassis for easier moving by removing a power supply. To determine the full weight of the chassis and the appropriate weight rating for the mechanical lift, see Weights and Quantities for the Chassis, Modules, Fan Trays, and Power Supplies.

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.

Step 1

If you need to make the chassis as light as possible for moving, you can optionally remove the fan tray and power supplies.

- To remove a power supply, follow these steps:

1. Push and hold the release handle on the power supply to the left.

2. Pull the power supply about two inches (about 5 cm) out of the chassis.

3. Place one hand under the power supply to support its weight and pull the power supply out of the chassis.

4. Place the power supply on an antistatic surface.

- To remove a fan tray, follow these steps:

1. Unscrew the two captive screws on the front of the fan tray.

2. Hold both handles on the fan tray with both of your hands and pull the fan tray out of the chassis.

3. Place the fan tray on an antistatic surface.

Step 2

Align the rear of the chassis to the front of the rack or cabinet.

Step 3

Push the chassis halfway onto the rack or cabinet.
Moving a Chassis onto a Rack or Cabinet

Total of four M3 screws (for brackets on both sides).

2

Total of eight M4 screws (for brackets on both sides).

Step 4

Push the chassis all the way onto the rack so that the vertical mounting brackets on the chassis come in contact with the vertical mounting rails on the rack.

Step 5

Use 2 center mount-brackets with eight M4 screws and two M3 screws to attach each of the two vertical mounting brackets on the chassis to the two vertical mounting rails on the rack. It is recommended to use a minimum of 8 screws (user preference from the accessory kit) on the front of the chassis to secure the chassis to the 2-post rack.
Attaching the Chassis to the Rack

1

Vertical mounting rails on the rack

2

Install a total of eight screws (user preference from the accessory kit) at the front to secure the chassis.

Step 6

If you removed the fan tray before moving the chassis, reinstall each one in the chassis as follows:

1. Holding each of the two handles on the fan tray with your two hands, align the fan tray to an open fan tray slot.

2. Slide the fan tray into the slot until the front of the fan tray comes in contact with the rear of the chassis.
Note:
The two alignment pins on the fan tray (on the left and the right) should go into holes in the chassis and the two captive screws on the fan tray should align to screw holes in the chassis.

3. Screw in the two captive screws to the chassis and tighten each screw to 8 in-lb (0.9 N·m).

Step 7

If you removed any power supplies before moving the chassis, reinstall each one as follows:

1. Determine which power supply slots to fill and ensure that each of those slots is open.
If you are using the combined or power supply redundancy mode, you can use any slot for the power supply that you are installing. If you are using the input-source or full redundancy mode, you must group the power supplies that are to be connected to the same grid on either the left or right power supply slots in the chassis.

2. Place one hand on the front of the power supply and place your other hand under it to support its weight.

3. Align the power supply to an open power supply slot.
Note:
The alignment bracket on top of the power supply should align to a track at the top of the slot and a bar at the bottom of the power supply should be guided by a track at the bottom of the slot.

4. Slide the power supply all the way into the slot until its release handle clicks and the module stops.

2 side C-shape brackets with four M3 screws.

Step 4

Push the chassis all the way onto the rack so that the vertical mounting brackets on the chassis come in contact with the vertical mounting rails on the rack.

Step 5

Use six screws (user preference from the accessory kit) at the front and four M3 screws at the back of the slide to secure the system chassis to the four-post rack
Attaching the Chassis to the Rack

1

Install six screws (user preference from the accessory kit) at the front.

2

Install 2 sliders to the C-shape bracket on each side of the chassis. Use four screws at the back of the slider to secure the chassis to the four-post rack.

Step 6

If you removed the fan tray before moving the chassis, reinstall each one in the chassis as follows:

1. Holding each of the two handles on the fan tray with your two hands, align the fan tray to an open fan tray slot.
Note:
The two alignment brackets on top of the fan tray should align to two tracks at the top of the slot.

2. Slide the fan tray into the slot until the front of the fan tray comes in contact with the rear of the chassis.
Note:
The two alignment pins on the fan tray (on the left and the right) should go into holes in the chassis and the two captive screws on the fan tray should align to screw holes in the chassis.

3. Screw in the two captive screws to the chassis and tighten each screw to 8 in-lb (0.9 N·m).

Step 7

If you removed any power supplies before moving the chassis, reinstall each one as follows:

1. Determine which power supply slots to fill and ensure that each of those slots is open.
If you are using the combined or power supply redundancy mode, you can use any slot for the power supply that you are installing. If you are using input-source or full redundancy mode, you must group the power supplies that are to be connected to the same grid on either the left or right power supply slots in the chassis.

2. Place one hand on the front of the power supply and place your other hand under it to support its weight.

3. Align the power supply to an open power supply slot.
Note:
The alignment bracket on top of the power supply should align to a track at the top of the slot and a bar at the bottom of the power supply should be guided by a track at the bottom of the slot.

4. Slide the power supply all the way into the slot until it stops.

5. Slide the handle in the middle of the ejector lever toward the end of the lever and rotate the lever to the front of the power supply. Release the middle handle.
Note:
The lever should grab the inside of the slot and push the power supply onto its mid plane connectors.

6. Screw in the two captive screws on the front of the power supply to the chassis. Tighten each screw to 8 in-lb (0.9 N·m).

Grounding a Switch Chassis

The switch is fully grounded as soon as you connect the chassis and the power supplies to the earth ground in the following ways:

- You connect the chassis to either a fully-bonded, grounded rack or to the data center ground.

Note

The system ground, also referred to as the network equipment building system (NEBS) ground, provides additional grounding for EMI shielding requirements and for the low-voltage supplies (DC-DC converters) on the modules. This grounding system is active even when the AC and HVAC/HVDC power cables are not connected to the system.

- You connect the AC and HVAC/HVDC power supplies to the earth ground automatically when you connect an AC or HVAC/HVDC power supply to an AC or HVAC/HVDC power source.

Before You Begin

Before you can ground the chassis, you must have a connection to the earth ground for the data center building. If you installed the switch chassis into a bonded rack (see the rack manufacturer's instructions for more information) that now has a connection to the data center earth ground, you can ground the chassis by connecting its grounding pad to the rack. Otherwise, you must connect the chassis grounding pad directly to the data center ground.

To connect the switch chassis to the data center ground, you need the following tools and materials:

- Grounding lug—A two-holed standard barrel lug that supports up to 6 AWG wire. This lug is supplied with the accessory kit.

- Grounding screws—Two M4 x 8 mm (metric) pan-head screws. These screws are shipped with the accessory kit.

- Grounding wire—Not supplied with the accessory kit. This wire should be sized to meet local and national installation requirements. Depending on the power supply and system, a 12 AWG to 6 AWG copper conductor is required for U.S. installations. We recommend that you use commercially available 6 AWG wire. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

- Number 1 manual Phillips-head torque screwdriver.

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

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

Step 1

Use a wire-stripping tool to remove approximately 0.75 inch (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 grounding lug as shown in the following figure.

Inserting a Grounding Wire in a Grounding Lug

1

NRTL listed 45-degree grounding lug

2

Grounding cable with 0.75 in. (19 mm) of insulation stripped from one end

Step 3

Use the crimping tool to crimp the lug to the grounding wire. Verify that the ground wire is securely attached to the grounding lug by attempting to pull the wire out of the crimped lug.

Step 4

Secure the grounding wire lug to the grounding pad with two M4 screws, and tighten the screws to 11.5 to 15 in-lb (1.3 to 1.7 N·m) of torque.

Step 5

Prepare the other end of the grounding wire and connect it to an appropriate grounding point in your site to ensure an adequate earth ground for the switch. If the rack is fully bonded and grounded, connect the grounding wire as explained in the documentation provided by the vendor for the rack.

Installing Cable Management Frames onto the Chassis

Before You Begin

- The chassis must be installed and secured to the rack.

- You must have the following tools and equipment:

- Manual Phillips screwdriver with torque capability (customer supplied).

- The following frames and screws (shipped with the switch):

- Two cable management side frames

- One cable management top hood frame

- One cable management bottom hood frame

- Two M4 and four M3 screws.

Step 1

Attach the two cable management frames to the chassis as follows:

1. Position one of the cable management side frame assemblies on the vertical mounting bracket attached to one side of the front of the chassis.

What to Do Next

You are ready to attach the optional door to the cable management frames.

Attaching the Front Door to the Chassis

Before installing the front door to the chassis, you must install an air filter to the front door.

Before You Begin

- Verify that the cable management frames are attached to the chassis.

- Verify that you have the following tools and equipment:

- Optional front door kit

- Number 1 manual Phillips torque screwdriver

Step 1

Install the air filter to the front door as follows:

1. Attach the air filter to the front door by aligning the plastic guides on the air filter with the slot holes on the front door.

Chapter 4. Connecting to the Network

This chapter contains the following sections:

- Guidelines for Connecting Ports

- Connecting a Console to the Switch

- Connecting the Management Interface

- Creating the Initial Switch Configuration

- Connecting Interface Ports to the Network

Guidelines for Connecting Ports

You can use and Small Form-Factor Pluggable (SFP) transceivers to connect the ports on the I/O modules to other network devices, which can include other switches or Fabric Extenders (FEXs). The SFP+ transceivers include Fabric Extender Transceivers (FETs) for connecting I/O modules with FEXs.

The transceivers used with copper cables come already assembled with their cables. The transceivers used with fiber-optic cables come separated from their cables. To prevent damage to the fiber-optic cables and their transceivers, we recommend that you keep the transceivers disconnected from their fiber-optic cables when installing the transceiver in the I/O module. Before removing a transceiver for a fiber-optic cable, remove the cable from the transceiver.

To maximize the effectiveness and life of your transceivers and optical cables, do the following:

- Wear an ESD-preventative wrist strap that is connected to an earth ground whenever handling transceivers. The switch is typically grounded during installation and provides an ESD port to which you can connect your wrist strap.

- Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions can shorten its useful life.

- Keep the transceivers and fiber-optic cables clean and dust free to maintain high signal accuracy and to prevent damage to the connectors. Attenuation (loss of light) is increased by contamination and should be kept below 0.35 dB.

- Clean these parts before installation to prevent dust from scratching the fiber-optic cable ends.

- Clean the connectors regularly; the required frequency of cleaning depends upon the environment. In addition, clean connectors if they are exposed to dust or accidentally touched. Both wet and dry cleaning techniques can be effective; refer to your site's fiber-optic connection cleaning procedures.

- Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other contamination.

- Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under a microscope to determine if damage has occurred.

Connecting a Console to the Switch

Before you create a network management connection for the switch or connect the switch to the network, you must create a local management connection through a console terminal and configure an IP address for the switch. You can also use the console to perform the following functions, each of which can be performed through the management interface after you make that connection later on:

- Configure the switch using the command-line interface (CLI).

- Monitor network statistics and errors.

- Configure Simple Network Management Protocol (SNMP) agent parameters.

- Download software updates.

You make this local management connection between the asynchronous serial port on a supervisor module and a console device capable of asynchronous transmission. Typically, you can use a computer terminal as the console device. On the supervisor modules, you use one of the following asynchronous serial ports:

- CONSOLE SERIAL PORT

This port is used for direct connections to the console.

Note

Before you can connect the console port to a computer terminal, make sure that the computer terminal supports VT100 terminal emulation. The terminal emulation software makes communication between the switch and computer possible during setup and configuration.

Before You Begin

- The switch must be fully installed in its rack, connected to a power source, and grounded.

- The necessary cabling for the console, management, and network connections must be available.

- An RJ-45 rollover cable and DB9F/RJ-45 adapter are provided in the switch accessory kit.

- Network cabling should already be routed to the location of the installed switch.

Step 1

Configure the console device to match the following default port characteristics:

- 9600 baud

- 8 data bits

- 1 stop bit

- No parity

Step 2

Route the RJ-45 rollover cable through the center slot in the cable management system and then to the console or modem.

Step 3

Connect the other end of the RJ-45 rollover cable to the console or to a modem.
If the console or modem cannot use an RJ-45 connection, use the DB-9F/RJ-45F PC terminal adapter found in the accessory kit for the switch. Alternatively, you can use an RJ-45/DSUB F/F or RJ-45/DSUB R/P adapter, but you must provide those adapters.

What to Do Next

You are ready to create the initial switch configuration (see Creating the Initial Switch Configuration).

Connecting the Management Interface

The supervisor management port (MGMT ETH) provides out-of-band management, which enables you to use the command-line interface (CLI) or the Cisco Data Center Network Manager (DCNM) interface to manage the switch by its IP address. This port uses a 10/100/1000 Ethernet connection with an RJ-45 interface.

Note

In a dual supervisor switch, you can ensure that the active supervisor module is always connected to the network by connecting the management interface on both supervisor modules to the network (that is, you can perform this task for each supervisor module). That way, no matter which supervisor module is active, the switch automatically has a management interface that is running and accessible from the network.

Caution

To prevent an IP address conflict, do not connect the MGMT 10/100/1000 Ethernet port until the initial configuration is complete. For more information, see Creating the Initial Switch Configuration.

Before You Begin

You must have completed the initial switch configuration (see Creating the Initial Switch Configuration).

Step 1

Connect a modular, RJ-45, UTP cable to the MGMT ETH port on the supervisor module.

Step 2

Route the cable through the central slot in the cable management system.

Step 3

Connect the other end of the cable to a 10/100/1000 Ethernet port on a network device.

What to Do Next

You are ready to connect the interface ports on each of the I/O modules to the network.

Creating the Initial Switch Configuration

You must assign an IP address to the switch management interface so that you can then connect the switch to the network.

When you initially power up the switch, it boots up and asks you a series of questions to configure the switch. To enable you to connect the switch to the network, you can use the default choices for each configuration except the IP address, which you must provide. You can perform the other configurations at a later time as described in the Cisco Nexus 7000 Series NX-OS Fundamentals Configuration Guide.

Note

You should also know the unique name needed to identify the switch among the devices in the network.

Before You Begin

- A console device must be connected with the switch.

- The switch must be connected to a power source.

- Determine the IP address and netmask needed for the following interfaces:

- Management (Mgmt0) interface

Step 1

Power up the switch by turning the power switch from standby () to on () with each power supply installed in the switch chassis.
The Input and Output LEDs on each power supply light up (green) when the power supply units are sending power to the switch, and the software asks you to specify a password to use with the switch.

Step 2

Enter a new password to use for this switch.
The software checks the security strength of your password and rejects your password if it is not considered to be a strong password. To increase the security strength of your password, make sure that it adheres to the following guidelines:

- At least eight characters

- Minimizes or avoids the use of consecutive characters (such as "abcd")

- Minimizes or avoids repeating characters (such as "aaabbb")

- Does not contain recognizable words from the dictionary

- Does not contain proper names

- Contains both uppercase and lowercase characters

- Contains numbers as well as letters

Examples of strong passwords include the following:

- If2CoM18

- 2004AsdfLkj30

- Cb1955S21

Note:
Clear text passwords cannot include the dollar sign ($) special character.

Tip:
If a password is trivial (such as a short, easy-to-decipher password), the software will reject your password configuration. Be sure to configure a strong password as explained in this step. Passwords are case sensitive.

If you enter a strong password, the software asks you to confirm the password.

Step 3

Enter the same password again.
If you enter the same password, the software accepts the password and begins asking a series of configuration questions.

Step 4

Until you are asked for an IP address, you can enter the default configuration for each question.
Repeat this step for each question until you are asked for the Mgmt0 IPv4 address.

Step 5

Enter the IP address for the management interface.
The software asks for the Mgmt0 IPv4 netmask.

Step 6

Enter a network mask for the management interface.
The software asks if you need to edit the configuration.

Step 7

Enter no to not edit the configuration.
The software asks if you need to save the configuration.

Step 8

Enter yes to save the configuration.

What to Do Next

You can now set up the management interface for each supervisor module on the switch.

Connecting Interface Ports to the Network

You can connect optical interface ports on I/O modules with other devices for network connectivity.

- Connecting a Fiber-Optic Cable to a Transceiver

- Disconnecting Optical Ports from the Network

- Maintaining Transceivers and Optical Cables

Connecting a Fiber-Optic Cable to a Transceiver

To prevent damage to the fiber-optic cables, do not place more tension on them than the rated limit and do not bend them to a radius less than 1 inch (2.54 cm) if there is no tension in the cable or 2 inches (5.08 cm) if there is tension in the cable.

To prevent possible damage to the cable or transceiver, install the transceiver in the port before installing the cable in the transceiver.

Step 1

Attach an ESD-preventative wrist strap and follow its instructions for use.

Step 2

Remove the dust cover from the port connector on the cable.

Step 3

Remove the dust cover from the cable end of the transceiver.

Step 4

Align the cable connector with the transceiver and insert the connector into the transceiver until it clicks into place (see the following figure for SFP or SFP+ transceivers).
Connecting an LC Optical Cable Plug to a Transceiver

If the cable does not install easily, ensure that it is correctly oriented before continuing.

Disconnecting Optical Ports from the Network

When removing fiber-optic transceivers, you must remove the fiber-optic cables from a transceiver before removing the transceiver from the port.

Maintaining Transceivers and Optical Cables

Transceivers and fiber-optic cables must be kept clean and dust free to maintain high signal accuracy and prevent damage to the connectors. Attenuation (loss of light) is increased by contamination and should be below 0.35 dB.

Consider the following maintenance guidelines:

- Transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventative wrist strap that is connected to the grounded chassis.

- Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions can shorten its useful life.

- Keep all optical connections covered when not in use. Clean them before using to prevent dust from scratching the fiber-optic cable ends.

- Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other contamination.

- Clean the connectors regularly; the required frequency of cleaning depends upon the environment. In addition, clean connectors if they are exposed to dust or accidentally touched. Both wet and dry cleaning techniques can be effective; refer to your site's fiber-optic connection cleaning procedures.

- Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under a microscope to determine if damage has occurred.

Displaying Temperatures for Modules

Each module has temperature sensors with two thresholds:

- Minor temperature threshold—When a minor threshold is exceeded, a minor alarm occurs and the following actions occur for all four sensors:

- Displays system messages

- Sends Call Home alerts (if configured)

- Sends SNMP notifications (if configured)

- Major temperature threshold—When a major threshold is exceeded, a major alarm occurs and the following actions occur:

- For sensors 1, 3, and 4 (outlet and onboard sensors), the following actions occur:

- Displays system messages.

- Sends Call Home alerts (if configured). For more information, refer Associating an Alert Group with a Destination Profile .

- Sends SNMP notifications (if configured). For more information, refer Enabling SNMP Notifications.

- For sensor 2 (intake sensor), the following actions occur:

- If the threshold is exceeded in a switching module, only that module is shut down.

- If the threshold is exceeded in an active supervisor module with HA-standby or standby present, only that supervisor module is shut down and the standby supervisor module takes over.

- If you do not have a standby supervisor module in your switch, you have up to 2 minutes to decrease the temperature. During this interval, the software monitors the temperature every 5 seconds and continuously sends system messages as configured.

Tip

We recommend that you install dual supervisor modules. If you are using a switch without dual supervisor modules, we recommend that you immediately replace the fan module if just one fan is not working.

Note

A threshold value of -127 indicates that no thresholds are configured or applicable.

You can display temperature readings for module temperature sensors by using the show environment temperature command.

Enter the show environment temperature command.

Example:

switch# show environment temperature

Connecting to a Module

At any time, you can connect to any module by using the attach module command. Once you are at the module prompt, you can obtain further details about the module by using module-specific commands in EXEC mode.

Step 1

Enter the attach module slot_number command.

Example:

switch# attach module 1
switch#

Provides direct access to the I/O module in slot 1 (in this example, the supervisor module is in slot 2).

Step 2

dir bootflash

Example:

switch# dir bootflash
Example:
switch# dir bootflash:
80667580     Feb 21 22:04:59 2008  n7700-s2-kickstart.7.3.0.DX.1.bin

switch#

Note:
To exit the module-specific prompt, use the exit command.

Tip:
If you are not accessing the switch from a console terminal, this step is the only way to access the standby supervisor module.

Saving the Module Configuration

To save the new configuration along with the non-default VDC configuration to nonvolatile storage, use the copy running-config startup-config vdc-all command from EXEC mode. Once you enter these commands, the running and the startup copies of the configuration are identical.

The following table lists various scenarios when module configurations are preserved or lost.

Scenario

Consequence

A particular switching module is removed and you used the copy running-config startup-config vdc-all command again.

The configured module information is lost.

A particular switching module is removed and the same switching module is replaced before you enter the copy running-config startup-config vdc-all command again.

The configured module information is preserved.

A particular switching module is removed and replaced with the same type switching module, and you entered the reload module slot_number command.

The configured module information is preserved.

A particular switching module is reloaded when you enter the reload module slot_number command.

The configured module information is preserved.

Displaying Power Usage Information

To display the power usage information for the entire switch, use the show environment power command. This command shows the power usage for many of the modules installed in the switch. For the older modules that do not have the capability to output this information, the output is shown as N/A.

Note

Power usage is reserved for both supervisor modules regardless of whether one or both supervisor modules are present.

Enter the show environment power command.

Reloading a Module

You can reset a module by using the reload module command and specifying the module by its slot number in the chassis.

Caution

Reloading a module disrupts traffic through the module.

Step 1

Enter the configure terminal command to enter the configuration terminal mode.

Example:

switch# configure terminal
switch(config)#

Step 2

Specify the slot number for the module that you are resetting by entering the reload module slot_numbercommand.

Example:

switch(config)# reload module 1

Rebooting the Switch

To reboot or reload the switch, use the reload command without any options. When you use this command, you reboot the switch.

Note

If you need to use the reload command, be sure to save the running configuration by using the copy running-config startup-config vdc-all command beforehand.

Step 1

Start the configuration mode by entering the configure terminal command.

Example:

switch# configure terminal
switch(config)#

Step 2

Save the running configuration by entering the copy running-config startup-config vdc-all command.

Example:

switch(config)# copy running-config startup-config vdc-all

Step 3

Reload the switch by entering the reload command.

Example:

switch(config)# reload

Accessing an I/O Module through a Console

You can troubleshoot bootup problems for an I/O module by accessing the module through its console port. This action establishes a console mode that you must exit in order to use other Cisco NX-OS commands.

To attach to the console port for an I/O module, use the attach console module command to specify the module you need to work with.

Note

To exit the console mode, enter the ~, command.

Attach to the console port for the I/O module by entering the attach console module slot_number command.

Example:

switch# attach console module 1
connected
Escape character is `~,' (tilde comma]

Displaying Information for the Installed Modules

You can display information about the modules installed in the switch chassis by using the show module command. This information includes module type, bootup status, MAC addresses, serial numbers, software versions, and hardware versions. You can use this command in the following ways to display information about all of the installed module or specific modules:

- For information on all modules, use the show module command.

- For information on a specific supervisor or I/O module, use the show module slot_number command to specify a slot number.

For a description of the module status indicated by one of the above show module commands, see the following table.

You can clear the running configuration for an I/O slot that is not functioning by using the purge module command in EXEC mode.

Note

This command does not work on supervisor slots nor on any I/O slot that currently has a powered-up module.

Before You Begin

Verify that either the I/O slot is empty or the I/O module installed in the slot is powered down.

Clear the running configuration by using the purge module slot_number running-config command.

Example:switch# purge module 1 running-config

Power Modes Overview

You can configure one of the following power modes to either use the combined power provided by the installed power supply units (no power redundancy) or to provide power redundancy when there is a power loss:

Combined mode

This mode allocates the combined power of all power supplies to active power for switch operations. This mode does not allocate reserve power for power redundancy in case of power outages or power supply failures.

Power-supply (n+1) redundancy mode

This mode allocates one power supply as a reserve power supply in case an available power supply fails. The remaining power supplies are allocated for available power. The reserve power supply must be at least as powerful as each power supply used for the available power.

Input-source (grid) redundancy mode

This mode allocates half of the power to available power and the other half to reserve power. You must use a different power source for the active and reserve power sources so that if the power source used for active power fails, the other power source used for the reserve power can provide power for the switch.

Full redundancy mode

This mode provides both power-supply (n+1) and input-source (grid) redundancies. As happens with the input-source redundancy mode, this mode allocates half of the power supplies to provide available power and the other half of the power supplies to provide the reserve power. One of the reserve power supplies can alternatively be used to provide power if a power supply supplying the available power fails.

- Guidelines for Configuring Power Redundancy Modes

- Configuring the Power Mode

Guidelines for Configuring Power Redundancy Modes

The amounts of available and reserve power depend on the power redundancy mode that you specify and the number of power supplies installed in the switch. For each redundancy mode, consider the following:

Combined mode

The available power equals the combined output of all installed power supplies. There is no reserve power. You activate this mode by using the power redundancy-mode combined command.

Power supply (n+1) redundancy mode

The power supply that outputs the most power provides the reserve power so that it can take over for any other power supply that fails, and all of the other installed power supplies provide the available power. You activate this power mode by using the power redundancy-mode ps-redundant command.

Input-source (grid) redundancy mode

The available power is provided by one power source and the reserve power is provided by the other power source. If the power source providing the available power fails, the switch uses the reserve power source to provide its required power. You activate this power mode by using the power redundancy-mode insrc_redundant command.

Full redundancy mode

Full redundancy provides both power-supply redundancy and input-source redundancy. For power-supply redundancy, the power supply with the most output provides reserve power and the other power supplies provide the available power. For input-source redundancy, the available power is provided by one power source and the reserve power is provided by another power source, with You activate this power mode by using the power redundancy-mode redundant command.

Configuring the Power Mode

You can configure the power supply mode by using the power redundancy-mode command.

Note

To display the current power supply configuration, use the show environment power command.

Step 1

Start the configuration mode by entering the configure terminal command.

Example:

switch# configure terminal
switch(config)#

Step 2

Specify one of the following power modes by entering the power redundancy-mode mode command:

- For combined mode, include the combined keyword.

- For power supply redundancy mode, include the ps-redundant keyword.

- For input source redundancy mode, include the insrc_redundant keyword.

- For full redundancy mode, include the redundant keyword.

Example:

switch(config)# power redundancy-mode redundant
switch(config)#

Overview of Fan Trays

The Cisco Nexus 7702 switch has one fan tray with three variable speed fans. The fan tray can be removed and replaced while the switch is operating without presenting an electrical hazard or damage to the switch. The switch can operate without the fan tray for up to two minutes. If a fan tray is not installed within that time, the switch will automatically shutdown.

Note

When one of the three fans in the fan tray fails, the remaining two fans run at a higher speed to compensate for the failed fan and keep the switch operating.

Tip

If one or more fans fail within a fan tray, the Fan Status LED turns red. A fan failure could lead to temperature alarms if not corrected immediately.

The fan status is continuously monitored by the software. In case of a fan failure, the following actions occur:

- System messages are displayed.

- Call Home alerts are sent (if configured). For more information, refer Associating an Alert Group with a Destination Profile .

- SNMP notifications are sent (if configured). For more information, refer Enabling SNMP Notifications.

- Using an ESD Wrist Strap to Prevent ESD Damage

- Installing or Replacing a Supervisor Module

- Installing or Replacing an I/O Module

- Replacing a Fan Tray

- Installing or Replacing a Power Supply in a Switch Chassis

Using an ESD Wrist Strap to Prevent ESD Damage

Before you touch any switch modules, you must ground yourself to protect the modules from electrostatic discharge (ESD). You can ground yourself by wearing an ESD wrist strap connected to a grounded chassis or a grounded rack.

Caution

Always handle modules by their carrier edges (typically the covered bottom, sides, and front of the module) and never touch the circuitry on the module.

Before You Begin

You must have a grounding connection close to where you are installing components in the chassis.

Step 1

Attach or wrap an ESD wrist strap to your arm.

Step 2

Attach the other end of the strap to the grounded chassis in one of the following ways:

- If the wrist strap has a banana plug on the other end, insert the plug into the ESD port on the chassis (see the following figure for the location of the port on the front of the chassis).

- If the wrist strap has an alligator clip on the other end, clip that onto one of the two screws holding the grounding lug to the chassis.

What to Do Next

After you ground yourself, you can replace the modules on the chassis.

Installing or Replacing a Supervisor Module

Before You Begin

Caution

The system will shut down when you remove the single supervisor module in the Cisco Nexus 7702 chassis.

- You must follow ESD protocols, including the following:

- You must wear a grounded ESD wristband (or other personal grounding device) whenever you handle the electronic modules outside the grounded chassis.

- You must carry electronic modules by only their covered edges or handles. Do not touch their electronic components.

- Whenever a module is outside a grounded chassis, place it flat on an antistatic surface or in an antistatic bag. Never lean the module on anything nor place anything else on top of the module nor lean anything on the module.

- Verify that the chassis is grounded (see Grounding a Switch Chassis).

- Verify that you have the following tools and equipment:

- ESD wrist strap (or other personal grounding device)

- Number 1 Phillips torque screwdriver

Manual torque screwdrivers are recommended. Be sure to never exceed the recommended torque setting for the screw that you are working with.

Align the bottom of the module to the module guides in the slot.

3. Rotate the end of the handle away from the front of the module until it stops (see Callout 1 in the previous figure).

4. With one hand under the supervisor module and the other hand holding the module by its front, align the rear of the module to the open supervisor slot.

5. Slide the module onto the guides inside the slot and push the module fully into the slot until you cannot push the module further.
The front of the module should be about 1/4 inch (0.6 cm) in front of the chassis.

6. Rotate the handle to the front of the module (see Callout 1 in the following figure) until it clicks when it reaches the front of the module.
The module should be fully inserted in the slot and the front of the module should be even with the fronts of all of the other installed modules. The captive screw by the ejector button on the module should be aligned to a screw hole on the chassis.

Securing a Supervisor Module to its Slot

1

Rotate the handle all the way to the front of the module.

2

Tighten the captive screw to 8 in-lb (0.9 N·m) of torque.

7. Screw in the captive screw to secure the module to the chassis (see Callout 2 in the previous figure). Tighten the screw to 8 in-lb (0.9 N·m) of torque.

8. Verify that the supervisor module LEDs turn on and appear as follows:

- STATUS LED is green.

- SYSTEM LED is green.

- ACTIVE LED is amber or green.

For more information about the LED states for this module, see Supervisor Module LEDs.

9. Attach the management cable to the MGMT ETH port.
The MGMT ETH LED should be green. If not, see Supervisor Module LEDs for information about the LED states.

Installing or Replacing an I/O Module

Before You Begin

- You must follow ESD protocols, including the following:

- You must wear a grounded ESD wristband (or other personal grounding device) whenever you handle the electronic modules outside the grounded chassis.

- You must carry electronic modules by only their covered edges or handles. Do not touch their electronic components.

- Whenever a module is outside a grounded chassis, place it flat on an antistatic surface or in an antistatic bag. Never lean the module on anything nor place anything else on top of the module nor lean anything on the module.

3. Screw in the two captive screws to secure the fan tray to the chassis and tighten them to 8 in-lb (0.9 N·m) of torque.

Installing or Replacing a Power Supply in a Switch Chassis

You can install up to two power supplies of the following types:

- 3-kW AC power supply (N77-AC-3KW)

- 3-kW DC power supply (N77-DC-3KW)

- 3.5-kW HVAC/HVDC power supply (N77-HV-3.5KW)

If you leave any power supply slots empty, you must install a blank filler plate (N77-3KPS-BLANK-H=) in that slot to maintain the designed airflow.

You follow the same steps to install AC, DC and HVAC/HVDC power supplies into the switch, but you ground them differently. For an AC and HVAC/HVDC power supply, you automatically ground it when you connect its power cable to the power supply and the power source. For a 3-kW DC power supply, you do not directly connect the power supply to the earth ground.

Before You Begin

- The switch chassis must be installed in a cabinet or rack that is secured to the data center.

You need the following additional tools and equipment:

- Nut driver attachment for Number 1 Phillips-head screwdriver or ratchet wrench with torque capability (used only for DC power supplies)

- Crimping tool

- Grounding wire—Size this wire to meet local and national installation requirements. For U.S. installations, you must use a 6 AWG copper conductor. For installations outside the U.S., consult your local and national electrical codes. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

Step 1

If you need to open a power supply slot for another power supply, follow these steps:
Note:
If you neet to remove a blank filler plate, unscrew its captive screws and pull it off the chassis. Go to Step 2.

1. Turn off the power for the power supply that you are removing, as follows:

1. Ensure that the power switch on the front of the power supply is set to standby (labelled as 0). The Output LED turns off.

2. Verify that the Output LED turns off. If the LED is still on, return to Step 1.

3. If you are removing a DC power supply, ensure that the power is turned off at the power source by turning off the power for that circuit, and verify that the Input LEDs turn off.

2. If you are removing a power supply, detach the power and ground cables as follows:

- For a 3-kW AC power supply, unplug the power cables that are attached to the power supply and the power source.

- For a 3-kW DC power supply, open the terminal box, and use a Phillips screwdriver to remove the power cables from their terminals. Replace the terminal box cover. Remove the power cables from the power source.

- For a 3.5-kW HVAC/HVDC power supply, release the built-in latch and unplug the power cable from the power source.

3. Remove the power supply or blank filler plate from the power supply slot as follows:
Note:
To remove a blank filler plate, unscrew its captive screws and pull on its handle to remove the plate from the slot.

- For a 3-kW power supply, press its ejector latch to the left, pull the power supply part way out of the slot by its handle, place your other hand under the module to support its weight, and pull it fully from the slot.

- For a 3.5-kW HVAC/HVDC power supply, disconnect the power cable from the power supply by pressing the release button on the power cable, pull the power supply part way out of the slot by its handle, place your other hand under the module to support its weight, and pull it fully from the slot.

Step 2

Install the new power supply in the open slot as follows:

1. Verify that the power switch on the front of the new power supply is set to standby (labelled as 0) and that the power supply is not connected to any power sources.

2. Hold the handle on the power supply with one hand, place your other hand under the power supply to support its weight, and position the power supply with its back end at the open power supply bay.

3. Slide the unit all the way into the power supply bay until one of the following situations occurs:

- For a 3-kW power supply, the release latch on the front of the power supply clicks and prevents you from moving the power supply in or out of the chassis. This action completes the mounting of the power supply on this chassis.

- For a 3.5-kW power supply, the built-in latch secures the power cable to the power supply.

What to Do Next

- For an AC and HVAC/HVDC (when used with an input AC source) power supply, you must connect it to an AC power source (see the “Connecting an AC Power Supply to AC Power Sources” and Click Here topic). The power supply will be automatically grounded through its power cable.

- For a 3-kW DC power supply, you must connect the power supply to the DC power source (see the “Connecting a DC Power Supply to DC Power Sources” topic).

- Connecting DC Power Supplies with Power Sources

- Connecting a 3.5-kW HVAC/HVDC Power Supply to DC Power Sources

Connecting a 3-kW AC Power Supply to AC Power Sources

You use one power cord to connect a 3-kW power supply to its AC power source and to ground the power supply. Depending on the power mode that you use for the switch, you either connect all of the power supplies to one AC power source or you connect half of the power supplies to one AC power source and the other half to another AC power source:

- For combined power mode (no power redundancy), you need enough power supplies to power all switch operations and connect all of the power supplies to the same AC power source. You can install the power supplies in any open power supply slot in the chassis.

- For power supply redundancy mode (n+1 redundancy mode), you need enough power supplies to power all switch operations and one extra power supply that can replace a failing power supply. You connect all power supplies to the same AC power source. You can install the power supplies in any open power supply slot in the chassis.

- For input source redundancy (grid redundancy) mode or full redundancy mode, you need twice the number of power supplies needed to power the switch operations. You connect half of the power supplies to one power source for active power and the other half to another power source for redundant power. You must ensure that the power supplies on the left side of the chassis are connected to one grid and that the power supplies on the right side of the chassis are connected to the other grid.

Before You Begin

Before you connect power supplies to one or two power sources, ensure all of the following:

- You have receptacles for one or two AC power sources within reach of the power supply cables. The number of power sources depends on the power mode to be used for the switch.

- Combined power (no power redundancy)—One AC power source

- Power supply redundancy (n+1 redundancy)—One AC power source

- Input source redundancy (power-grid redundancy)—Two AC power sources

- Full redundancy—Two AC power sources

- The AC power sources are rated as follows:

- For North American installations—20A with 110V or 220V circuits.

- For international installations—size the circuits by local and national standards.

- The power supply is already installed in the chassis.

- The chassis is connected to an earth ground.

Step 1

Ensure that the power supply switch located on the front of the power supply is set at standby (labeled as 0).

Step 2

Plug one AC power cable into the power supply, and pull down the retention clip over the plug on the power cable.

Step 3

Plug the other end of the power cable into a AC power source supplied by the data center.
Note:
If you are using the combined power mode or power supply redundancy, you connect the power cables to the same 20-A circuit. If you are using the input source redundancy mode or full redundancy mode, you connect half of the power cables to one AC power source and the other half to another AC power source.

Warning:
Take care when connecting units to the supply circuit so that wiring is not overloaded.

Warning:
This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than:

250V, 20 A

Step 4

Turn the power supply switch from standby to on (from 0 to 1 as labeled on the power switch).

Step 5

Verify that the power supply is receiving AC power and outputting DC power by making sure that the INPUT and OUTPUT power supply LEDs are lit and the FAULT LED is not lit or flashing. For an explanation of all the power supply LEDs and the conditions that they indicate, see Table D-5.
Note:
When you first activate the power supply, you can verify the functionality of the LEDs by checking that each LED turns on for a couple of seconds.

If the Fault LED is flashing red, turn the power switch to standby (labeled as 0), check the AC power connections on the power supply and the AC power source, and then turn the power switch back on (labeled as 1). The Input and Output LEDs for the connected power supplies should be green and the Fault LED should be off.

Connecting a 3.5-kW HVAC/HVDC Power Supply to AC Power Sources

You use one power cord to connect a 3.5-kW HVAC/HVDC power supply to its AC power source and to ground the power supply. Depending on the power mode that you use for the switch, you either connect all of the power supplies to one AC power source or you connect half of the power supplies to one AC power source and the other half to another AC power source:

- For combined power mode (no power redundancy), you need enough power supplies to power all switch operations and connect all of the power supplies to the same AC power source. You can install the power supplies in any open power supply slot in the chassis.

- For power supply redundancy mode (n+1 redundancy mode), you need enough power supplies to power all switch operations and one extra power supply that can replace a failing power supply. You connect all power supplies to the same AC power source. You can install the power supplies in any open power supply slot in the chassis.

- For input source redundancy (grid redundancy) mode or full redundancy mode, you need twice the number of power supplies needed to power the switch operations. You connect half of the power supplies to one power source for active power and the other half to another power source for redundant power. You must ensure that the power supplies on the left side of the chassis are connected to one grid and that the power supplies on the right side of the chassis are connected to the other grid.

Before You Begin

Before you connect power supplies to one or two power sources, ensure all of the following:

- You have receptacles for one or two AC power sources within reach of the power supply cables. The number of power sources depends on the power mode to be used for the switch.

- Combined power (no power redundancy)—One AC power source

- Power supply redundancy (n+1 redundancy)—One AC power source

- Input source redundancy (power-grid redundancy)—Two AC power sources

- Full redundancy—Two AC power sources

- The AC power sources are rated as follows:

- For North American installations—20A with 110V or 220V circuits.

- For international installations—size the circuits by local and national standards.

- The power supply is already installed in the chassis.

- The chassis is connected to an earth ground.

Step 1

Ensure that the power supply switch located on the front of the power supply is set at standby (labeled as 0).

Step 2

Plug the AC power cable into the power supply. The built-in latch secures the power cable to the power supply. You can disconnect the power cable from the power supply by pressing the release button on the power cable.

Step 3

Plug or connect the other end of the power cable into a AC power source supplied by the data center.
Note:
If you are using the combined power mode or power supply redundancy, you connect the power cables to the same 20-A circuit. If you are using the input source redundancy mode or full redundancy mode, you connect half of the power cables to one AC power source and the other half to another AC power source.

Warning:
Take care when connecting units to the supply circuit so that wiring is not overloaded.

Warning:
This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than:

250V, 20 A

Step 4

Turn the power supply switch from standby to on (from 0 to 1 as labeled on the power switch).

Step 5

Verify that the power supply is receiving AC power and outputting DC power by making sure that the INPUT and OUTPUT power supply LEDs are lit and the FAULT LED is not lit or flashing. For an explanation of all the power supply LEDs and the conditions that they indicate, see Table D-5.
Note:
When you first activate the power supply, you can verify the functionality of the LEDs by checking that each LED turns on for a couple of seconds.

If the Fault LED is flashing red, turn the power switch to standby (labeled as 0), check the power connections on the power supply and the AC power source, and then turn the power switch back on (labeled as 1). The Input and Output LEDs for the connected power supplies should be green and the Fault LED should be off.

Connecting DC Power Supplies with Power Sources

Connect each installed DC power supply with a DC power circuit as follows:

Note

If you are using combined power mode (no power redundancy) or power supply (n+1) power mode, connect all of the power supplies to the same power circuit (grid).

Before You Begin

- The power supplies are installed in the chassis.

- A DC power source is within reach of power cables that will be attached to the power supplies.

- Power cables are available to connect each DC power supply to the DC power source.

Step 1

Turn the power switch to standby (labeled 0 on the power switch).

Step 2

Turn off the power at the circuit breakers for the portions of the DC grid power that you are connecting to and verify that all of the LEDs on the power supplies are off.
Warning:
Before performing any of the following procedures, ensure that power is removed from the DC circuit.

Step 3

Size the power cables to the distance between the power supply and the DC power grid. If you need to cut the cable, cut it at the end that connects to the DC power grid, remove 0.75 inch (19 mm) of insulation from the cut ends, and attach them to the DC power system. Be sure to connect the negative cables to negative lines and positive cables to positive lines.
Note:
For all your power connections, if you are using cables with two different colors, use one color cable for all positive circuits and the other color for all negative circuits.

Warning:
Hazardous voltage or energy may be present on DC power terminals. Always replace the cover when the terminals are not in service. Be sure uninsulated conductors are not accessible when cover is in place.

Step 4

Remove the three screws that hold down the safety cover for the terminal box on the front of the DC power supply and remove the cover (see the following figure).
Note:
The terminal box has four slots for four power terminals (ordered as negative [-], positive [+], positive [+], and negative [-]). Each terminal has two nuts that you use to fasten a power cable to the terminal.

Removing the Safety Cover for the Terminal Box on a 3-kW DC Power Supply

1

Remove three screws from the safety cover.

2

Remove the cover.

Step 5

Install four cables (two positive and two negative cables) in the four terminal slots as follows:

1. Unscrew the two nuts in each of the four terminal slots.

2. Attach and crimp each lug to the end of each power cable.

3. Attach each cable lug to the two terminal posts in each slot, fasten with two nuts, and tighten to 40 in-lb (4.5 N·m).
Note:
For all your power connections, if you are using cables with two different colors, use one color cable for all positive circuits and the other color for all negative circuits.

4. Replace the safety cover on the terminal box and fasten with three screws.

Step 6

Install the four cables from the DC power supply to a DC power source as follows:

1. If the unconnected end of each power cable is not stripped of its insulation for the last 0.75 inches (19 mm), use wire strippers to remove that amount of insulation.

2. Attach the negative cables to the negative terminals of a DC power source, and attach the positive cables to the positive terminals of the same power source.
Note:
If you are using combined power mode or power supply redundancy mode, connect all the power supplies in the chassis to the same power source. If you are using input source redundancy mode or full redundancy mode, connect half the power supplies to one DC power source and the other half of the power supplies to another DC power source.

Step 7

For the powered down circuits connected to the power supplies, turn on the power at the circuit breaker. The Input 1 (IN1) and Input 2 (IN2) LEDs turn on each connected power supply.

Step 8

Turn on the power supply by setting the power switch to 1. The LEDs should flash and then the Output LED should turn on in addition to the Input LEDs.
If the FAULT LED is lit or flashing, call Cisco TAC for assistance.

What to Do Next

You are ready to connect the switch to the network.

Connecting a 3.5-kW HVAC/HVDC Power Supply to DC Power Sources

You use one power cord to connect a 3.5-kW HVAC/HVDC power supply to its DC power source and to ground the power supply. Depending on the power mode that you use for the switch, you either connect all of the power supplies to one DC power source or you connect half of the power supplies to one DC power source and the other half to another DC power source.

Before You Begin

Before you connect power supplies to one or two power sources, ensure all of the following:

- The power supply is already installed in the chassis.

- A DC power source is within reach of power cables that will be attached to the power supplies.

- Power cables are available to connect each HVAC/HVDC power supply to the DC power source.

Step 1

Ensure that the power supply switch located on the front of the power supply is set at standby (labeled as 0).

Step 2

Plug the DC power cable into the power supply. The built-in latch secures the power cable to the power supply. You can disconnect the power cable from the power supply by pressing the release button on the power cable.

Step 3

Plug or connect the other end of the power cable into a DC power source supplied by the data center.
Note:
Connect the power supply to the appropriate polarity and ground as indicated on the power cable plug or as marked on the ring lug cable.

Warning:
Take care when connecting units to the supply circuit so that wiring is not overloaded.

Warning:
This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than:

250V, 20 A

Step 4

Turn the power supply switch from standby to on (from 0 to 1 as labeled on the power switch).

Step 5

Verify that the power supply is receiving DC power by making sure that the INPUT and OUTPUT power supply LEDs are lit and the FAULT LED is not lit or flashing. For an explanation of all the power supply LEDs and the conditions that they indicate, see Table D-5.
Note:
When you first activate the power supply, you can verify the functionality of the LEDs by checking that each LED turns on for a couple of seconds.

If the Fault LED is flashing red, turn the power switch to standby (labeled as 0), check the HVAC/HVDC power connections on the power supply and the DC power source, and then turn the power switch back on (labeled as 1). The Input and Output LEDs for the connected power supplies should be green and the Fault LED should be off.

1000BASE-CWDM SFP Transceiver Cables

The Coarse Wavelength Division Multiplexing (CWDM) SFP transceivers are hot-swappable transceivers that you plug into SFP-compatible I/O modules. The CWDM SFP transceiver uses an LC optical connector to connect to a single-mode fiber-optic (SMF) cable. You can connect the CWDM SFPs to CWDM passive optical system optical add/drop multiplexer (OADM) modules or multiplexer/demultiplexer plug-in modules using SMF cables. CWDM SFP transceivers can transmit and receive optical signals up to 61 miles (100 km) depending on the quality of the fiber-optic cable used.

CWDM SFP transceivers are color coded to indicate their designated optical wavelength. The following figure shows the CWDM transceiver, which looks like a standard 1000BASE-X SFP transceiver with a colored arrow and bail clasp to indicate the designated wavelength.
