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

Procedure

Step 1

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).

Step 2

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.

Step 3

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.

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.

Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when

servicing.

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or

view directly with optical instruments.
