Unpack and Install the Chassis

Mount Chassis Into the Rack

What to do next
After moving the chassis to the room or area where you will install it, begin the procedure to mount the chassis into the rack.
Mount Chassis Into the Rack
To accommodate equipment racks with different mounting hole patterns, the chassis mounting brackets have groups of screw holes on either side. The mounting holes in the chassis mounting brackets are spaced so that one mounting hole in each hole group aligns with a corresponding hole in the equipment rack. By using the corresponding mounting hole (in the same hole group) on the opposite side of the chassis, you can level the chassis in the rack.

Note To lift the chassis, use a mechanical lift. Do not use the handles on the side of the chassis. Use the side handles for only repositioning the chassis after it is already on the mechanical lift or in the rack or cabinet.

Step 1 Step 2 Step 3

Powering on the Switch

This chapter describes how to connect the power modules in the chassis and to power on the switch. · Power Module Overview, on page 29 · Connect HVAC Power Supply to Power Source, on page 30 · Power Supply Power Cord Specifications, on page 32
Power Module Overview
You can install an AC power module in the chassis. Ensure all power connection wiring conforms to the rules and regulations in the National Electrical Code (NEC) as well as local codes. The chassis has a power assembly shelf that supports the following number of power trays:
· Cisco 9804 chassis contains two power trays Each power tray supports up to three AC power modules.
Note Use only one kind of power tray and power module in the chassis.
Note Use only the same capacity power module in the chassis. Do not mix different capacity power modules.
High-Voltage AC Power Supplies HVAC power modules operate in the input range of 180 VAC to 305 VAC (nominal input level of 200 to 240 VAC, 277 VAC).
· NXK-HV-6.3KW20A-A: Each 6.3 KW, 20A power module can supply up to 6.3 KW to the power tray when it’s supplied by two feeds (A and B). It can supply up to 3.15 KW with only one feed.
· NXK-HV-6.3KW30A-A: Each 6.3 KW, 30A power module can supply up to 6.3 KW to the power tray when it’s supplied by two feeds (A and B). It can supply up to 4.8 KW with only one feed.
Cisco Nexus 9804 NX-OS Mode Switch Hardware Installation Guide 29

Connect HVAC Power Supply to Power Source

Powering on the Switch

Connect HVAC Power Supply to Power Source
The HVAC power supply has 2 redundant input power lines. It can provide a power output of 6.3 kW from each input power line with 2 inputs operating, or provide 4.8 kW (30A) or 3.15 kW (20A) output from either input with one input operating. The HVAC power supply provides n+n or n+x line redundancy mode in a single power supply for the switch.
The HVAC power supply accepts a maximum of 305VAC or 400VDC input power.
If you are not using power redundancy or are using n+1 power redundancy, you can connect all the power supplies in the chassis to the same power grid on the rear end of each power tray. If you are using n+n power redundancy, connect one redundant grid to one of the power supply inputs and the other redundant grid to the other power supply input on the back of the power tray as shown for each power supply. To enable grid redundancy, you must connect the corresponding inlet of power supplies to the correct power grids. For example, first inlet of all PS slots correspond to Grid-A and second inlet of all PS slots correspond to Grid-B.
Before you begin
· Turn off the power source at its circuit breaker.
· Check that the power switch is set to the STANDBY (0) position on the power tray.
· NXK-HV-6.3KW30A-A: The HVAC power sources are rated for 30A maximum input current.
· NXK-HV-6.3KW20A-A: The HVAC power sources are rated for 20A maximum input current.

Step 1 Step 2

Choose your power supply (HVAC) and use a Saf-D-Grid power cable to connect to the power supply tray. For HVAC input, connect a Saf-D-Grid AC power cable to the Saf-D-Grid receptacle.

Connect Switch to the Network

Note The images in this chapter are only for representation purposes, unless specified otherwise. The chassis’ actual appearance and size may vary.
· Connecting a Console to the Switch, on page 37 · Connect the Management Interface, on page 38 · Transceivers, Connectors, and Cables, on page 39 · Install and Remove QSFP Transceiver Modules, on page 40 · Connect Interface Ports, on page 44 · Maintain Transceivers and Optical Cables, on page 45 · Create the Initial Switch Configuration, on page 45
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. The switch can be accessed using remote management protocols, such as SSH and Telnet. By default, SSH is included in the software image. But telnet is not part of the software image. You must manually install the telnet optional package to use it. You also can use the console to perform the following functions, each of which can be performed through the management interface after you make that connection:
· configure the switch using the command-line interface (CLI) · monitor network statistics and errors · configure Simple Network Management Protocol (SNMP) agent parameters · initiate software download updates via console
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 module, you use the console serial port.
Cisco Nexus 9804 NX-OS Mode Switch Hardware Installation Guide 37

Connect the Management Interface

Connect Switch to the Network

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. The switch must be connected to a power source and grounded. · The necessary cabling for the console, management, and network connections must be available. · An RJ45 rollover cable and a DB9F/RJ45 adapter. · Network cabling should already be routed to the location of the installed switch.

Step 1
Step 2 Step 3

Configure the console device to match the following default port characteristics: · 115200 baud · 8 data bits · 1 stop bit · No parity
Connect and RJ45 rollover cable to a terminal, PC terminal emulator, or terminal server. The RJ45 rollover cable is not part of the accessory kit. Route the RJ45 rollover cable as appropriate and connect the cable to the console port on the chassis. If the console or modem cannot use an RJ45 connection, use the DB9F/RJ45F PC terminal adapter. Alternatively, you can use an RJ45/DSUB F/F or RJ45/DSUB R/P adapter, but you must provide those adapters.

What to do next You are ready to create the initial switch configuration.
Connect the Management Interface
The Supervisor Module’s management port (MGMT ETH) provides out-of-band management, which lets you to use the command-line interface (CLI) to manage the switch by its IP address. This port uses a 10/100/1000 Ethernet connection with an RJ-45 interface.

Cisco Nexus 9804 NX-OS Mode Switch Hardware Installation Guide 38

Connect Switch to the Network

Transceivers, Connectors, and Cables

Note In a dual Supervisor Module switch, you can ensure that the active Supervisor Module is always connected to the network by connecting the management interface on both Supervisor Module to the network. That is, you can perform this task for each Supervisor Module. When the 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 100/1000 Ethernet port until the initial configuration is complete.
Before you begin You must have completed the initial switch configuration.

Step 1 Step 2 Step 3

Connect a modular, RJ-45, UTP cable to the MGMT ETH port on the Supervisor Module. Route the cable through the central slot in the cable management system. Connect the other end of the cable to a 100/1000 Ethernet port on a network device.

What to do next You are ready to connect the interface ports on each of the line cards to the network.

Required Tools and Equipment

Required Tools and Equipment
You need these tools to install the transceiver modules: · Wrist strap or other personal grounding device to prevent ESD occurrences. · Antistatic mat or antistatic foam to set the transceiver on. · Fiber-optic end-face cleaning tools and inspection equipment.
Installing the Transceiver Module
Caution The transceiver module is a static-sensitive device. Always use an ESD wrist strap or similar individual grounding device when handling transceiver modules or coming into contact with system modules.

Caution

Protect the transceiver ports by inserting clean dust caps (NXA-ACC-QDD-DC) into any ports not in use. Be sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another module. Use dust caps for all the open ports on the chassis.
The switch ships with dust caps plugged in. We highly recommend you to keep the dust caps plugged in until you are ready to plug an optic.
The dust caps protect the ports from possible EMI interference and also avoid contamination due to dust collection. To meet the EMI interference requirements, you must use the metal dust caps when the ports are not in use by optical modules.

The QSFP transceiver module has a pull-tab latch. To install a transceiver module, follow these steps:

Step 1 Step 2 Step 3
Step 4 Step 5

Attach an ESD wrist strap to yourself and a properly grounded point on the chassis or the rack.
Remove the transceiver module from its protective packaging.
Check the label on the transceiver module body to verify that you have the correct model for your network. Do not remove the dust plug until you’re ready to attach the network interface cable. Dust plug is not shown in the images.
Hold the transceiver by the pull-tab so that the identifier label is on the top.
Align the transceiver module in front of the module’s transceiver socket opening and carefully slide the transceiver into the socket until the transceiver contact with the socket electrical connector.

Before you begin Before you remove the dust plugs and make any optical connections, follow these guidelines:
· Keep the protective dust plugs installed in the unplugged fiber-optic cable connectors and in the transceiver optical bores until you are ready to make a connection.
· Inspect and clean the optical connector end faces just before you make any connections.
Cisco Nexus 9804 NX-OS Mode Switch Hardware Installation Guide 42

Connect Switch to the Network

Attach the Optical Network Cable

· Grasp the optical connector only by the housing to plug or unplug a fiber- optic cable.

Note The transceiver modules and fiber connectors are keyed to prevent incorrect insertion.

Note The multiple-fiber push-on (MPO) connectors on the optical transceivers support network interface cables with either physical contact (PC) or ultra- physical contact (UPC) flat polished face types. The MPO connectors on the optical transceivers do not support network interface cables with an angle- polished contact (APC) face type.

Note Inspect the MPO connector for the correct cable type, cleanliness, and any damage. For complete information on inspecting and cleaning fiber-optic connections, see the Inspection and Cleaning Procedures for Fiber-Optic Connections document.

Step 1 Step 2

Remove the dust plugs from the optical network interface cable MPO connectors and from the transceiver module optical bores. Save the dust plugs for future use. Attach the network interface cable MPO connectors immediately to the transceiver module.

Cisco Nexus 9804 NX-OS Mode Switch Hardware Installation Guide 44

Connect Switch to the Network

Disconnect Optical Ports from the Network

Caution Removing and installing a transceiver can shorten its useful life. Do not remove and insert transceivers any more than is absolutely necessary. We recommend that you disconnect cables before installing or removing transceivers to prevent damage to the cable or transceiver.
Disconnect Optical Ports from the Network
When you need to remove fiber-optic transceivers, you must first remove the fiber-optic cables from the transceiver before you remove the transceiver from the port.
Maintain Transceivers and Optical Cables
Refer to Inspection and Cleaning Procedures for Fiber-Optic Connections document for inspection and cleaning processes for fiber optic connections.
Create the Initial Switch Configuration
You must assign an IP address to the switch management interface to connect the switch to the network. When you initially power up the switch, it boots up and asks a series of configuration-related questions. You can use the default choices for each configuration except for the IP address, which you must provide. When the system is powered on and the console port is connected to the terminal, the RP CPU messages are seen. You can see RP CPU messages by pressing the hot-key sequence Ctrl-O.
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 that is needed for the Management interfaces: MgmtEth0/RP0/CPU0/0 :

Step 1 Step 2

Power up the switch.
The 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.
When the system is booted up for the first time, a new username and a password is to be created. The following prompt appears:

· 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 on board sensors), the following actions occur: · Displays system messages.
· Sends SNMP notifications (if configured).
· Logs environmental alarm event that can be reviewed by running the show alarm command.
· For sensor 2 (intake sensor), the following actions occur: · If the threshold is exceeded in a switching card, only that card is shut down.
· If the threshold exceeds 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.

Note

Cisco recommends that you install dual Supervisor Module.

Note The images in this chapter are only for representation purposes, unless specified otherwise. The chassis’ actual appearance and size may vary.
Caution Whenever you replace any card, you must always ensure to secure the ejector thumbscrews properly. · Replace Chassis Door Foam Air Filters, on page 63 · Replace a Supervisor Module, on page 64 · Replace a Line Card, on page 69 · Replace a Fan Tray, on page 70 · Replace Fabric Module, on page 73 · Replace Power Supply Components, on page 80
Replace Chassis Door Foam Air Filters
Note In general, we recommend that you inspect the air filter every 3 months and replace. The front doors come with pre-installed air filters (N9K-9804-DF- KIT). If air filters need a replacement, follow this procedure.
Step 1 Remove the two quarter turn fasteners from the front door as shown.
Cisco Nexus 9804 NX-OS Mode Switch Hardware Installation Guide 63

Replace a Supervisor Module Figure 38: Replace Air Filter

Replace Chassis Components

Step 2 Step 3

Install the new door filters on both the front doors. Tighten the two quarter turn fasteners back on the doors.

Replace a Supervisor Module
The switch supports up to two redundant Supervisor Modules (N9K-C9800-SUP-A). When two Supervisor Modules are installed in the switch, one acts as an active module and the other as the standby module. When the active Supervisor Module is removed, the switch automatically makes the standby Supervisor module active. If the switch has only one Supervisor Module that is installed, a new Supervisor can be installed in the empty Supervisor slot during operation.
Note Single Sup is supported for this switch.

Warning

Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and fire, they contain electromagnetic interference (EMI) that might disrupt other equipment, and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Caution

Unlatching the right ejector lever, so that it disengages from the latch lock (Callout 1 in above figure) triggers graceful shutdown of the Supervisor if the module is up. If the module shuts down then wait for the Supervisor status LED to turn off before proceeding.
Moving the latch to the side does not disengage the latch from the lock. This is a safeguard mechanism if an operator initiated shutdown of the supervisor has not been performed before opening the levers. The ejector open will be logged.

Step 1
Step 2 Step 3

Open the packaging for the new Supervisor Module, inspect the module for damage, and verify that the module is the same type as the other Supervisor Module installed in the chassis.
If the module is damaged, alert the Technical Assistance Center (TAC).
If you are installing the module in an empty slot, remove the blank that is already in that slot by unscrewing its captive screw and pulling it out of the slot. Go to Step 4. If you are replacing a module that is currently in the chassis, remove the existing module from the chassis by following these steps: a) Run the poweroff module (x)location command, in EXEC mode, which gracefully shuts down Supervisor module
to prevent any of the file systems from being corrupted. b) Verify that the Supervisor Status LED for the slot that you specified turns to Amber. Also, you can use the show
module command to verify that the status of the module is SHUT DOWN. c) Disconnect the cables from the module. d) If there are any external drives attached to the module through its USB ports, detach those drives. e) Loosen the two captive screws (one on each side of the RP) until the screws are no longer in contact with the chassis. f) Slide the latch on each of the ejector lever outwards from the lever center (see Callout 1 in the below figure).
This action disengages the ejector levers from the faceplate.

Cisco Nexus 9804 NX-OS Mode Switch Hardware Installation Guide 66

Replace Chassis Components Figure 40: Remove Supervisor Module from Chassis

Replace a Supervisor Module

g) Pull to rotate the levers away from the front of the module (see Callout 2 in the above figure)

The module unseats its connectors from the midplane and moves slightly out of the chassis.

h) Use one hand to hold the front of the module, place your other hand under the module to support its weight, pull the module out of the chassis, and set it on an antistatic surface or inside an antistatic bag.

Note

While performing OIR of the module, wait for 30 seconds before inserting the same or new module in

the same slot. This will allow the module to boot properly and reach operational state.

Step 4

To install a new module, follow these steps: a) If any of the ejector levers are in closed position slide the latch on the ejector lever outwards from the lever center
and pull to rotate the lever away from the front of the module.
This action opens the lever so that the module can be fully inserted into the slot.
b) Hold the front of the module with one hand and place your other hand under the module to support its weight. c) Align the back of the module to the guides in the open Supervisor slot and slide the module all the way into the slot.

Cisco Nexus 9804 NX-OS Mode Switch Hardware Installation Guide 67

Replace a Supervisor Module

Replace Chassis Components

The module stops when its front is about 0.25 inches (0.6 cm) outside the front of the chassis.

d) Rotate the levers firmly all the way to the front of the chassis. Then firmly push the tip of the levers towards the faceplate till the latch hook locks in place behind the faceplate. You may hear a click or see the latch engage. (See Callout 1 in the below figure.)

Make sure that the other end of both levers engages behind the latching slot on the faceplate so that the module fully seats onto the connectors on the midplane.

Note

To confirm that the module is installed properly, pull the black tip of each ejector lever lightly, and make

sure the lever does not pop out.

e) Screw in the two captive screws to secure the module to the chassis. Tighten the screws to 8 in-lb (0.9 N·m) of torque. f) Attach the cables to the module. g) Verify that the Supervisor module status LEDs turn on and appear green.

Replace a Line Card
The switch can operate with one or more line cards that are installed in the chassis. If there is at least one line card that is installed and operating in the chassis, you can replace another line card or install a new line card in an empty line card slot.
The Cisco Nexus 9800 series switches support OIR of line cards.

Warning

Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and fire, they contain electromagnetic interference (EMI) that might disrupt other equipment, and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

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

Step 1 Step 2
Step 3

Open the packaging for the new line card and inspect the module for damage.
If the module is damaged, contact the Technical Assistance Center (TAC).
If you are replacing a module that is currently in the chassis, remove the existing module from the chassis by following these steps:
a) Run the poweroff module (x) location command, which gracefully shuts down the line card. b) Verify that the Line Card LED for the slot that you specified turns off. Also, you can use the show module command
to verify that the status of the card is SHUT DOWN. c) Disconnect and label each of the interface cables from the module. d) Loosen the two captive screws. e) Press the ejector buttons and use the levers to pull the module a couple of inches (about 5 cm) from the chassis. Rotate
each of the two ejector levers away from the center of the chassis. The levers unlock themselves from the brackets on the side of the chassis. f) Close the ejector levers. g) Use one hand to hold the front of the module, place your other hand under the module to support its weight, pull it out of the chassis, and set it on an antistatic surface or inside an antistatic bag.
To install the new module, follow these steps:
a) Hold the front of the module with one hand and place your other hand under the module to support its weight. b) Align the back of the module to the guides in the open line card slot and slide the module all the way into the slot
(see the following figure).

1 Rotate the ejector handle on each end of the module 3 Slide the module all the way into the slot. away from the center of the chassis.
2 Align the bottom of the back of the module with tracks on either side of the slot.
c) Rotate the ends of the two levers toward the center of the chassis. When the levers point straight out from the chassis, their other ends should be locked onto the brackets on the side of the chassis. As you rotate the levers, the front of the module moves all the way to the front of the chassis and the module fully seats on the chassis.
d) Tighten the two captive screws to 8 in-lb (0.9 Nm) torque. e) Attach each interface cable to the appropriate port on the line card. Use the label on each cable to determine which
port each cable attaches to. f) Verify that the line card LEDs turn on and appear green.
Replace a Fan Tray
You can remove a fan tray, to either replace it with another fan tray, or to replace a fabric card located behind it. The switch uses four fan trays but it can operate with three fan trays while you replace one or remove one, to replace one of the fabric cards behind the fan tray. When you remove one fan tray, the other fan trays speed up their fans to maintain the designed airflow.
Cisco Nexus 9804 NX-OS Mode Switch Hardware Installation Guide 70

Replace Chassis Components

Remove Fan Tray

Note If you cannot replace a fan tray within three minutes, we recommend that you leave it in the chassis until you are ready to replace it.

Note Never remove two fan trays at a time during operation, the switch allows up to two minutes of operations before shutting down unless you replace the missing fan tray within that time. If the switch senses an over temperature condition when multiple fan trays are removed, the shutdown can occur in less than two minutes.
To replace a fan tray, you must perform the following functions: 1. Remove the fan tray.
2. Install a fan tray.

Remove Fan Tray
Remove only one fan tray at a time during switch operations. If you remove more than one fan tray at a time, the switch shuts down within two minutes unless you replace the extra fan trays that you removed within that time.

Step 1 Step 2 Step 3

Unscrew the four captive screws on the front of the fan tray until each screw is free of the chassis. Hold both handles on the front of the fan tray with both of your hands and pull the fan tray out of the slot. Set the fan tray on antistatic material or inside an antistatic bag.

Position the fan tray with its rear (the side with the electrical connectors) at the opening for the fan tray slot in the chassis. Align the two tracks on the top of the fan tray with the two sets of rails at the top of the open fan tray slot in the chassis. Slide the fan tray all the way into the slot until the front of the fan tray touches the chassis. Make sure that the four captive screws on the front of the fan tray align with the four screw holes in the chassis.
Screw in the four captive screws to secure the fan tray to the chassis. Tighten the screws to 8 in-lb (0.9 N·m) of torque. Verify that the fan tray STATUS LED turns on and becomes green, approximately within 20 seconds.

Replace Fabric Module
The switch supports replacement of a fabric module while others are operating. To replace a fabric module, you must do each of the following:
· Shut down the fabric module being replaced. · Remove the fan tray covering the fabric module in the chassis. · Remove the fabric module. · Install the new fabric module.
Note We recommend that you insert the fabric modules in the sequence starting with FM1, FM2, and so on (from left to right). Use the adjacent module as a guide to retain the modules in vertical position.
· Reinstall the fan tray over the fabric module. · Activate the fabric module.
The Cisco 9800 series switches support OIR of fabric module. To maintain the designed airflow while you remove the fan tray, the fans in the other fan trays increase their speed. During operations, it is required that you remove only one fan tray at a time and reinstall that fan tray within three minutes to avoid the possibility of having the switch overheat and shut down. If you remove more than one fan tray at a time, the switch shuts down if you do not reinstall the extra missing fan trays within two minutes (the shutdown can occur earlier if the switch over heats).
Remove a Fabric Module
Before you begin · You must wear an electrostatic discharge (ESD) wrist strap or other ESD protective device while handling modules. · Prepare an antistatic surface or packing materials for each module that you remove from the chassis.

Step 2 Step 3

Unscrew the two captive screws (one on each ejector handle) and rotate the ejector handles at least 30 degrees. Ensure that the locking posts on the top and bottom of the chassis rotate into the module so that the module can slide fully into the slot.
Place one hand on the front of the module and turn the module 90 degrees so that the electrical connectors are on the bottom.
Align the guide bar on the bottom of the fabric module into the guide slot at the bottom of the fabric module slot, and make sure that the guide rails on the top of the fabric module align with the track on the top of the slot.

Note

The lower guide rail extends to the back of the chassis. The upper guide rail does not connect until the

module is halfway into the chassis.

Since the Fan trays are blocking the view, fabric module LEDs might not be visible. Therefore, you can verify the fabric module LEDs status using show module command.

Replace Power Supply Components
The Cisco Nexus 9800 series switches support OIR of power modules. If you are replacing a redundant power module, you can replace the power module while the system remains powered on without any electrical hazard or damage to the system. This feature enables you to replace a power module while the system maintains all routing information and ensures session preservation. However, to maintain operational redundancy and proper cooling, and to meet EMI compliance standards, you must have at least one working redundant power module that is installed. When you remove a failed power module with the switch in operation, perform the replacement as quickly as possible. Make sure you have the replacement power module ready before beginning the removal and installation procedure.
Note For the RP to communicate properly to a power module in a power tray, input power to at least one of the power modules in the power tray should be present.
This section contains procedures on how to replace the power modules.
Caution Do not turn off the switch on the power tray to remove individual power modules. Power modules support OIR, so they can be removed and replaced with the power on and the system operating.
