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
Step 4
Using your mechanical lift, raise the chassis so that it is in level with or
not more than 1/4 inch [0.635cm] above the rails.
Push the chassis all the way onto the rack so that the vertical mounting
brackets on the front of the chassis come in contact with the vertical
mounting rails on the rack.
Use screws provided with the rack to secure the chassis with the vertical
mounting rails on the rack.
Note
You should remove the power shelf to facilitate attaching chassis to the rack.
Use the screws provided with the rack to attach the chassis rear rails.

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.

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.

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

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

characters (such as “abcd”) · minimizes or avoids repeating characters (such
as “aaa”) · 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
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 rejects that password.
Passwords are case sensitive.
When you enter a strong password, the software asks you to confirm the password.
Reenter the password. When you enter the same password, the software accepts the password.
Enter the configuration mode. Enter the IP address for the management interface. Enter a network mask for the management interface. The software asks whether you want to edit the configuration. Enter ‘no’ to decline.
Verify Chassis Installation
After installing the chassis, use the following show commands to verify the installation and configuration in the EXEC mode. Any issue if detected, take corrective action before making further configurations.

show environment temperature
Description
Displays temperature readings for card temperature sensors. Each Supervisor
Module, line card, and fabric cards have temperature sensors with two
thresholds:
· Minor temperature threshold When a minor threshold is exceeded, minor
alarm occurs and the following actions occur for all four sensors: · Displays
system messages
· Sends SNMP notifications (if configured)
· Log environmental alarm event that can be reviewed by running the show alarm
command.
· 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.

Replace Chassis Components
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

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.

Replace Chassis Components
Replace a Line Card
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).

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.

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.
Install Fan Tray
Before you begin · Fan tray slot is open in the chassis. · If you are
replacing a fabric card behind the open fan tray slot, ensure that the fabric
card replacement operation is completed.

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.

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.
