Chapter 3 Installing a Network Module

Removing a Network Module

Note

The switch meets the applicable compliance and thermal specifications when a network module is
present. If no uplink ports are required, install a blank network module.

Step 1

Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.

Caution

Do not remove the network module with installed SFP cables or modules. Always remove any cables
and modules before removing the network module from the slot.

Caution

A module interface might become error-disabled when a network module with connected fiber-optic
cables is installed or removed. If an interface is error-disabled, you can reenable the interface by using
the shutdown and no shutdown interface configuration commands.

Step 2

Disconnect the cables from the SFP modules.

Step 3

Remove the SFP modules from the network module.

Step 4

Loosen the captive screws that hold the network module in place.

Step 5

Carefully press the tab on the right side of the network module to release it. Grasp the edges of the
module, and carefully slide it out of the slot.

Step 6

Install a replacement network module or a blank module in the slot.

Step 7

Place the module that you removed in an antistatic bag or other protective environment.
