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.
Caution
Step 2
Disconnect the cables from the pluggable transceiver module.

chassis.
Step 5
Carefully slide the network module 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.
