Removing a Network Module
Note
The switch complies with EMC, safety, and thermal specifications when a network module is present. If no
uplink ports are required, install a blank network module.
Note
To avoid authentication failure and non-detection of modules, wait for a minimum of 6-8 seconds between
the online insertion and removal (OIR) of network modules.
Procedure
Step 1
Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface
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.
Do not remove the network module with connected cables or installed pluggable transceiver modules.
Always remove any cables and modules before you remove the network module.
