Overview of the Cisco Nexus 9408 Switch

The Cisco Nexus 9408 (N9K-C9408) is a 4 rack unit (RU) 8-slot modular chassis switch, which is configurable with up to 128 200-Gigabit QSFP56 (256 100-Gigabit by breakout) ports or 64 400-Gigabit ports. This switch supports port-side intake airflow. The switch requires four AC power supplies for operation, and offers 2+2 power grid redundancy.

This switch includes these high-power optics and MACsec:

- The N9K-X9400-16W LEM (linecard expansion module) offers full MACsec (128 ports) for a full load chassis with no limitation for 200G optics.

- The N9K-X9400-8D LEM offers full MACsec (64 ports) for a full load chassis but with a limit of 400G high power optics within 32pcs among 8 slots (maximum of 32 ports of 20-W optics irrespective of MACsec), and the high power optics can go in any of the 400G ports.

- The N9K-X9400-22L LEM offers 22 front ports supporting 10G, 25G, or 50G.

This switch can have up to 8 LEM slots which are online swappable. Use any combination of 200G/400G/50G LEMs in the 8 slots.

- Clearance Requirements

Temperature Requirement

This switch is rated to operate at 32 to 104°F (0 to 40°C). It can be stored at -40 to 158°F (-40 to 70°C).

Humidity Requirement

High humidity can cause moisture to enter 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 withstand from 5- to 95-percent (nonoperating) and 5- to 90-percent (operating) relative humidity.

Buildings cooled with air conditioning during warm months and warmed during cold months usually maintain an acceptable level of humidity. However, if the site is unusually humid, use a dehumidifier to maintain the required humidity level.

Altitude Requirements

High-altitude (low-pressure) conditions outside of 0 to 5,000 feet (0 to 1524 m) can reduce the cooling efficiency and cause electrical problems.

Dust and Contaminants

To prevent contaminant buildup and increased internal chassis temperatures, make sure that the operating environment is as clean as possible and free of dust and other contaminants. Do not permit smoking, food, or drinks 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. 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 as transmitted radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and RFI that are emitted by computing equipment. Each switch meets these FCC regulations.

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

- Cover all open expansion slots with a blank filler plate.

- 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 to the signals on the wires with these 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, consult experts in radio frequency interference (RFI).

The wiring is unlikely to emit radio interference if you use a 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.

Caution

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 that is caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic switches. Consult experts in electrical surge suppression and shielding if you have 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.

Grounding Requirements

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

When the chassis is properly installed in a grounded rack, the switch is grounded because it has a metal-to-metal (no paint, stain, dirt, or anything else on it) connection to the rack. Alternatively, ground the chassis by using a customer-supplied grounding cable that meets your local and national installation requirements. For U.S. installations, we recommend 6-AWG wire. Connect your grounding cable to the chassis with a grounding lug (provided in the switch accessory kit) and to the facility ground.

Note

You automatically ground AC power supplies when you connect them to AC power sources. For DC power supplies, you must connect a grounding wire when wiring the power supply to the DC power source.

Note

Create an electrical conducting path between the product chassis and the metal surface of the enclosure, or rack in which it is mounted, or to a grounding conductor. Provide electrical continuity by using thread-forming type mounting screws that remove any paint or non-conductive coatings and establish a metal-to-metal contact. Remove any paint or other non-conductive coatings on the surfaces between the mounting hardware and the enclosure or rack. Clean the surfaces and apply an antioxidant before installation.

Rack and Cabinet Requirements

Install these 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

To install the switch in a cabinet that is located in a hot-aisle and cold-aisle environment, 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 these requirements or see the Cisco Technical Assistance Center (TAC) for recommendations:

- Use a standard 19-inch (48.3-cm), 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 7.1-RU (12.4 inches or 31.6 cm) height of the switch and its bottom support bracket.

- 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 rails (for proper mounting of the bottom-support brackets or other mounting hardware).

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

- 4.5 inches (11.4 cm) between the front of the chassis and the front of the rack or interior of the cabinet (required for cabling and module handles).

- 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).

Also, you must consider these site requirements for the rack:

Also, you must have power receptacles that are located within reach of the power cords that are used with the switch.

Warning

Statement 1048—Rack Stabilization

The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before installation or servicing. Failure to stabilize the rack can cause bodily injury.

Clearance Requirements

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

- Environmental requirements for temperature, humidity, altitude, and air particulates.

- Cabinet or rack is installed and meets the requirements for the switch.

Note

Jumper power cords are available for use in a cabinet.

- The rack is positioned so that you can install the switch with its cold air intakes positioned in a cold aisle.

If the fan and power supply modules are burgundy or red colored, you must install the chassis with its port side in a cold aisle. If the modules are blue colored, you must be able install the chassis with the fan modules in a cold aisle.

- Earth ground connection is close to the switch. You must be able to easily connect the switch directly to an earth ground or indirectly through a grounded rack.

Caution

High leakage current. Earth connection essential before connecting to power supply.

- Site power meets the switch requirements. If you are using n+n redundancy, you must have two power sources within reach of the switch when it is installed in the cabinet or rack.

If available, you can use an uninterruptible power supply (UPS) to protect against power failures.

Caution

Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems such as the Cisco Nexus switches. These switches can have substantial current draw fluctuations because of fluctuating data traffic patterns.

Ensure that circuits are sized according to local and national codes. For North America, the power supply requires a 15-A or 20-A circuit.

Caution

To prevent loss of input power, ensure the total maximum loads on the circuits supplying power to the switch are within the current ratings for the wiring and breakers.

- There is adequate clearance around the rack to install the switch and to allow for unimpeded airflow.

- You have the following equipment in addition to the switch and the kits shipped with the switch:

- Eight customer-supplied 12-24 or 10-32 screws (required for attaching slider rails and mounting bracket to the mounting rails)

- Number 1 and number 2 Phillips screwdrivers with torque capability

- 3/16-inch flat-blade screwdriver

- Tape measure and level

- ESD wrist strap or other grounding device (wrist strap can be found in the accessory kit)

- Antistatic surface large enough to place the switch

- Grounding cable (6 AWG recommended), sized according to local and national installation requirements; the required length depends on the proximity of the switch to proper grounding facilities

- Crimping tool large enough to accommodate the girth of the grounding lug

- Wire stripping tool

- 10-32 screws— Use 20 in-lb (2.26 N·m) of torque.

If the rack requires another type of screw, use the appropriate torque setting for that type of screw.

Grounding the Chassis

The switch chassis is automatically grounded when you properly install the switch in a grounded rack with metal-to-metal connections between the switch and rack.

You can alternatively ground the chassis (this is required if the rack is not grounded) by attaching a customer-supplied grounding cable to the chassis grounding pad and the facility ground.

Note

The location of the grounding pad on each switch can be found in the Overview section.

Note

An electrical conducting path shall exist between the product chassis and the metal surface of the enclosure or rack in which it is mounted or to a grounding conductor. Electrical continuity shall be provided by using thread-forming type mounting screws that remove any paint or non-conductive coatings and establish a metal-to-metal contact. Any paint or other non-conductive coatings shall be removed on the surfaces between the mounting hardware and the enclosure or rack. The surfaces shall be cleaned and an antioxidant applied before installation.

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

- You connect the chassis (at its grounding pad) to the data center ground. If the rack is fully-bonded and grounded, you can ground the switch by connecting it to the rack.

Note

The chassis ground connection is active even when the power supply modules have not been grounded or connected to the switch.

Warning

Statement 1024—Ground Conductor

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Warning

Statement 1046—Installing or Replacing the Unit

When installing or replacing the unit, the ground connection must always be made first and disconnected last

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 installing it into the rack. Otherwise, you must connect the chassis grounding pad directly to the data center ground.

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 grounding lug, and use a crimping tool to crimp the lug to the wire (see Callout 2 in the following figure). Verify that the ground wire is securely attached to the grounding lug by attempting to pull the wire out of the crimped lug.

To power up the switch, follow these steps:

Before you begin

- Verify that the switch is fully installed and secured to a rack.

- Verify that the switch is adequately grounded to the facility earth ground or to a grounded rack.

- Verify that all of the fan and power supply modules are installed in the chassis. If the chassis has less than 4 power supplies, there must be a blank module (NXA-PS-BLANK) in the open power supply slot to maintain the designed airflow.

Procedure

Step 1

If the switch has AC power supplies, connect those power supplies to an AC power source as follows:

1. Verify that the AC power source is turned off at the circuit breaker.

2. Plug the power cable into the power receptacle on the power supply.

3. Attach the other end of the power cable to the AC power source.

4. Turn on the power at the circuit breaker.

5. Verify that the power supply is functioning by making sure that the OK LED turns green and the FAULT LED is off.

Step 2

Listen for the fans; they should begin operating when the power cable is plugged in.

Step 3

After the switch boots, verify that the following LEDs are on:

- Power supply LED—lit and green

If not green, try removing the module part way from its slot and reinstalling it.

- Fan LED—lit and green

If not green, try removing the module part way from its slot and reinstalling it.

- System Status LED—lit and green (if this LED is orange or red, then one or more environmental monitors is reporting a problem.)

- Link LEDs for the Ethernet connector—Off

- Connecting to a Console

- Connecting the Management Interface

- Connecting Interface Ports to Other Devices

- Maintaining Transceivers and Optical Cables

- Creating the Initial Switch Configuration

Preparing for Network Connections

When preparing your site for network connections to your switch, consider the following for each type of interface and gather all the required equipment before connecting the ports:

- Cabling required for each interface type

- Distance limitations for each signal type

- Additional interface equipment required

Connecting to a Console

You can connect the switch to a console to perform the following functions:

- Configuring the switch using the CLI

- Monitoring network statistics and errors

- Configuring SNMP agent parameters

- Downloading software updates

Note

We recommend that you use this port to create a local management connection to set the IP address and other initial configuration settings before connecting the switch to the network for the first time.

The console port on the switch is an RS-232 port with an RJ-45 interface. This is an asynchronous (async) serial port; any device connected to this port must be capable of asynchronous transmission.

Caution

The console port can be used to connect to a modem. If you do not connect it to a modem, connect it either before powering the switch on or after the switch has completed the boot process.

Before you begin

Before you connect the switch to a console, ensure that you have the following:

- Computer terminal that supports VT100 terminal emulation. The terminal emulation software (such as HyperTerminal or Procomm Plus) makes communication between the switch and a computer possible during setup and configuration.

Procedure

Step 1

Configure the terminal emulator program to match each of the following default port characteristics:

- 9600 baud

- 8 data bits

- 1 stop bit

- No parity

Step 2

Connect the DB-9 connector on the other end of the cable to the computer serial port.

What to do next

You are ready to configure the switch.

Connecting the Management Interface

Before you begin

To prevent an IP address conflict, you must complete the initial configuration and establish an IP address for the switch.

Procedure

Step 1

Connect the appropriate modular cable to on the switch.

Step 2

Connect the other end of the cable to the switch, hub, or router.

Connecting Interface Ports to Other Devices

After you perform the initial configuration for the switch and create a management connection, you are ready to connect the interface ports on the switch to other devices. Depending on the types of interface ports on the switch, you will need to use interface cables with QSFP+, SFP+, or SFP transceivers or RJ-45 connectors to connect the switch to other devices.

The transceivers used with many fiber-optic cables come separated from their cables. To prevent damage to the fiber-optic cables and their transceivers, we recommend that you keep these transceivers disconnected from their fiber-optic cables when installing the transceiver in the interface port. Before removing a transceiver for a fiber-optic cable, you must 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.

Warning

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

- Installing SFP+ and SFP Transceivers

- Installing QSFP+ Transceivers

- Installing SFP+ and SFP Optical Cables

Installing SFP+ and SFP Transceivers

Note

Excessively removing and installing an SFP or SFP+ transceiver can shorten its life. Unless it is absolutely necessary, do not remove and insert SFP or SFP+ transceivers. To prevent damage to an optical cable and transceiver, we recommend that you disconnect cables before installing or removing transceivers.

Note

If you cannot install the cable into the transceiver, insert or leave the dust plug in the cable end of the transceiver.

Procedure

Step 1

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

Step 2

Remove the dust cover from the port cage.

Step 3

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

Step 4

Insert the transceiver into the port as follows:

- If the transceiver has a Mylar tab latch, position the transceiver with the tab on the bottom, and then gently insert the transceiver into the port until it clicks into place.

- If the transceiver has a bale clasp latch, position the transceiver with the clasp on the bottom, close the clasp by pushing it up over the transceiver, and then gently insert the transceiver into the port until it clicks into place.

Caution

If the transceiver does not install easily, ensure that it is correctly positioned and the tab or clasp are in the correct position before continuing.

Installing QSFP+ Transceivers

The QSFP+ transceiver module can have either a bail-clasp latch or a pull-tab latch.

Caution

The QSFP+ transceiver module is a static-sensitive device. Always use an ESD wrist strap or similar individual grounding device when handling QSFP+ transceiver modules or coming into contact with system modules.

Procedure

Step 1

Attach an ESD wrist strap to yourself and a properly grounded point on the chassis or the rack. Follow its instructions for use.

Step 2

Remove the QSFP+ transceiver module from its protective packaging.

Step 3

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

Step 4

Check the label on the QSFP+ transceiver module body to verify that you have the correct model for your network.

Step 5

For optical QSFP+ transceivers, remove the optical bore dust plug and set it aside.

Step 6

For transceivers equipped with a bail-clasp latch, do the following:

1. Keep the bail-clasp aligned in a vertical position.

2. Align the QSFP+ transceiver in front of the module's transceiver socket opening and carefully slide the QSFP+ transceiver into the socket until the transceiver makes contact with the socket electrical connector.

Step 7

For QSFP+ transceivers equipped with a pull-tab, do the following:

1. Hold the transceiver so that the identifier label is on the top.

2. Align the QSFP+ transceiver in front of the module's transceiver socket opening and carefully slide the QSFP+ transceiver into the socket until the transceiver makes contact with the socket electrical connector.

Installing SFP+ and SFP Optical Cables

Note

To prevent damage to an optical cable and transceiver, disconnect cables before installing or removing transceivers.

Procedure

Step 1

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

Step 2

Remove the dust cover from the 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.

Caution

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

Note

If you cannot install the cable into the transceiver, insert or leave the dust plug in the cable end of the transceiver.

For instructions on verifying connectivity, see the appropriate Cisco Nexus Series configuration guide.

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. Contamination increases attenuation (loss of light) 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 the fiber-optic connection cleaning procedures for your site.

- 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.

Creating the Initial Switch Configuration

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 connect the switch to the network, use the default choices for each configuration except the IP address, which you must provide. You can perform the other configurations later as described in the Cisco Nexus 9000 Series NX-OS Fundamentals Configuration Guide.

Note

Know the unique name that is needed to identify the switch among the devices in the network.

Guidelines for the N9K-9400-16W

Be aware of these limitations:

- For ports 1-16, every pair of ports (1,2 | 3,4 | 5,6 | 7,8 | 9,10 | 11,12 | 13,14 | 15,16) is referred to as a QUAD group. They all must operate at the same speed.

- All the ports in a QUAD operate in 10G with QSA, or 40G, 100G, or 200G.

- Mixed speed is not supported within the same QUAD with these exceptions:

- Mixed speeds of 40G and 100G can be supported in a QUAD.

- 100G-CR2 cannot be mixed with either 40G or other types of 100G optics in a QUAD.

Note

Do not remove or insert optics when the LEM is powered off or offline. If you do, the software cannot detect the optics and this may lead to an inconsistent port state.

Guidelines for the N9K-9400-22L

Be aware of these limitations:

- For ports 1-22, every group of consecutive four ports (i.e., 1-4, 5-8, 11-14,15-18, 19-22) and two ports 9-10 are referred to as a QUAD group. They all must operate at the same speed.

- All the ports in a QUAD operate in 10G, or 25G, or 50G.

- Mixed speed is not supported within the same QUAD with these exceptions:

- A mixed speed of 10G and 25G can be supported in a QUAD.

Note

Do not remove or insert optics when the LEM is powered off or offline. If you do, the software cannot detect the optics and this may lead to an inconsistent port state.

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 the netmask that is needed for the Management (Mgmt0) interface.

Procedure

Step 1

Power up the switch by connecting each installed power supply to an AC circuit.

If you are using the input-source (n+n) power mode, connect half of the power supplies to one AC circuit. Connect the other half of the power supplies to another AC circuit.

The Input and Output LEDs on each power supply light up (green) when the power supply units are sending power to the switch. The software asks you to specify a password to use with the switch.

Step 2

Enter a new password for this switch.

The software checks the security strength of your password. It rejects your password if it does not meet these 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 and letters.

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. Configure a strong password as explained in this step. Passwords are case-sensitive.

When 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, 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

Set up the management interface for each supervisor module on the switch.

Chapter 5. Replacing Modules

- Replacing a 4 (RU) Fan Module

- Replacing an AC Power Supply

- Replacing a Supervisor Module

- Installing or Replacing a Line-Card Expansion Module (LEM)

- Replacing a Switch Card

- Fiber Optic Removal Using the Optics Extraction Tool

Replacing a 4 (RU) Fan Module

The fan module is designed to be removed and replaced while the system is operating without causing an electrical hazard or damage to the system if the replacement is performed within one minute.

If you do not have the appropriate replacement fan module, leave the original fan module in its slot to preserve the designed airflow for the switch until you have the replacement fan module. The module number can be found on the chassis.

Caution

The fans might be turning when you remove the fan assembly from the chassis. Keep fingers, screwdrivers, and other objects away from the openings in the fan assembly's housing.

Before you begin

- Verify that you have an ESD wrist strap or other device to prevent ESD damage for components that you touch.

- Verify that you have an antistatic surface or bag for placing the fan module that you remove from the chassis.

- Verify that the replacement fan module has the correct direction of airflow (it has the same coloring as the other fan and power supply modules in the same chassis).

Procedure

Step 1

Attach an ESD wrist strap or other ESD device to your body and an earth ground to prevent ESD damage.

You can attach the ESD device to any earth ground or grounded object, such as a grounded rack or ground connection on a chassis.

Step 2

Remove the fan module that you are replacing as follows:

1. On the fan module that you are removing, unscrew the two captive screws on the front of the fan module until each screw is free of the chassis.

2. Holding the handle, pull the module out of the chassis and set it on an antistatic surface or in a antistatic bag.

Caution

Do not touch the electrical connectors on the back side of the module and prevent anything else from coming into contact with and damaging the connectors.

Step 3

Install the replacement fan module as follows:

1. Hold the fan module with two hands. One hand holding its handle, and one hand supporting the weight of the fan module. Align the back of the fan module (the side with the electrical connectors) to the open fan slot in the chassis.

2. Slide the fan module into the slot until it clicks in place.

3. Tighten the fan module captive screws.

4. Verify that the Status (STS) LED turns on and becomes green.

Replacing an AC Power Supply

You can replace an AC power supply during operations so long as there is another power supply installed and operating during the replacement. The switch requires two power supplies for operations, so you can hot swap the redundant power supply during operations. If there are only two power supplies installed in the chassis, you can replace one by installing the new power supply in the open power supply slot before removing the other power supply. The module number can be found on the chassis.

Note

This switch supports port-side intake power supplies only (NXA-PAC-2KW-PI)

Before you begin

- Verify that you have an ESD wrist strap or other device to prevent ESD damage to the components that you touch.

- Verify that you have an antistatic surface or bag for placing the power supply module that you remove from the chassis.

- Verify that the replacement power supply module has the correct direction of airflow (it has the same coloring as the other fan and power supply modules in the same chassis). Otherwise the switch can overheat and shut down.

Procedure

Step 1

Attach an ESD wrist strap or other ESD device to your body and an earth ground to prevent ESD damage.

You can attach the ESD device to any earth ground or grounded object, such as a grounded rack or ground connection on a chassis.

Step 2

Remove the power supply as follows:

1. Pull the power cord out from the power receptacle on the power supply to be removed and verify that the OK LED turns off.

2. Remove the power supply from the chassis by pushing and holding its thumb latch to the left and pulling the power supply part way out of the chassis.

3. Place your other hand under the power supply to support it while you slide it out of the chassis.

Either place the power supply on an antistatic surface or pack it in its packing materials.

4. If the power supply slot is to remain empty, install a blank power supply filler panel (part number NXA-PS-BLANK).

Step 3

Install the replacement power supply as follows:

1. Holding the replacement power supply with one hand underneath the module and the other hand holding the handle, align the back end of the power supply (the end with the electrical connections) to the open power supply slot and slide the power supply all the way into the slot until it clicks into place.

2. Test the installation by trying to pull the power supply out of the slot without using the release latch.

If the power supply does not move out of place, it is secured in the slot. If the power supply moves, press it all the way into the slot until it clicks in place.

Step 4

Connect the new power supply to an AC power source as follows:

1. Attach the power cable to the electrical outlet on the front of the power supply.

2. Connect the other end of the power cable to an AC power source.

- For no power redundancy, connect one power supply to one power source.

- For n+1 redundancy, connect two power supplies to one or two power sources.

- For n+n redundancy, connect each of two power supplies to a different power source.

Note

Depending on the outlet receptacle on your power distribution unit, you might need the optional jumper cable to connect the switch to your outlet receptacle.

3. Verify that the power supply is operational by checking that the power supply OK LED is green.

Rack Specifications

- General Requirements and Guidelines for Cabinets and Racks

- About Requirements for Perforated Cabinets

- About Requirements for Open Racks

General Requirements and Guidelines for Cabinets and Racks

The cabinet or rack must have all of the following characteristics:

- Standard 19-inch (48.3 cm) four-post EIA cabinet or rack.

- Mounting rails that conform to English universal hole spacing per section 1 of ANSI/EIA-310-D-1992). See below.

The cabinet or rack must also meet the following requirements:

- The minimum vertical rack space per Cisco Nexus switch chassis must be one RU (rack units), equal to 1.75 inches (4.4 cm).

- The width between the rack-mounting rails must be at least 17.75 inches (45.0 cm) if the rear of the device is not attached to the rack. For four-post EIA racks, this measurement is the distance between the two front rails.

Four-post EIA cabinets (perforated or solid-walled) must meet the following requirements:

- The minimum spacing for the bend radius for fiber-optic cables should have the front-mounting rails of the cabinet offset from the front door by a minimum of 3 inches (7.6 cm).

- The distance between the outside face of the front mounting rail and the outside face of the back mounting rail should be 23.0 to 30.0 inches (58.4 to 76.2 cm) to allow for rear-bracket installation.

- A minimum of 2.5 inches (6.4 cm) of clear space should exist between the side edge of the chassis and the side wall of the cabinet. No sizeable flow obstructions should be immediately in the way of chassis air intake or exhaust vents.

Note

To help with cable management, consider planning additional space in the rack or cabinet above and below the chassis to make it easier to route all of the fiber optic or copper cables through the rack.

About Requirements for Perforated Cabinets

A perforated cabinet has perforations in its front and rear doors and side walls. In addition to the requirements listed in the “General Requirements for Cabinets and Racks” section, perforated cabinets must meet the following requirements:

- The front and rear doors must have at least a 60-percent open area perforation pattern, with at least 15 square inches (96.8 square cm) of open area per rack unit of door height.

- The roof should be perforated with at least a 20-percent open area.

- The cabinet floor should be open or perforated to enhance cooling.

The Cisco R Series rack conforms to these requirements.

About Requirements for Open Racks

In addition to the requirements listed in the “General Requirements for Cabinets and Racks” section on page A-1, if you are mounting the chassis in an open rack (no side panels or doors), ensure that the rack meets the following requirements:

- The minimum vertical rack space per chassis must be two rack units (RU), equal to 3.47 inches (8.8 cm).

- The horizontal distance between the chassis and any adjacent chassis should be 6 inches (15.2 cm), and the distance between the chassis air vents and any walls should be 2.5 inches (6.4 cm).
