Online Insertion and Removal on a WS-4500X-32
Note Unscheduled uplink module removal is not supported because the C4KX-NM-8 module has hardware
communication lines to the baseboard that cannot be unplugged in an online state. Communication must
be stopped first.
Before removing the uplink module, you must press the OIR button for 5 seconds, and wait for the OIR LED to turn Green.
Removing a module without pressing the OIR button causes the system to reboot to ROMMON with the following console
error message:
Kernel panic - not syncing: Removing a module from switch causes instability.
Rebooting in 15 seconds...
Note No special steps are needed for insertion.
With Cisco Release IOS XE 3.3.0SG and IOS 15.1(1)SG, two CLI’s are introduced: hw-module module number start and
hw-module module number stop. For the number keyword, the only applicable value for WS-C4500 is 2. With Cisco Release
IOS XE 3.3.0SG and IOS 15.1(1)SG, the start and stop commands are only enabled on the uplink module of WS-4500X-32.
For details, please refer to the hardware portion of the documentation library:

Shutting down a Module
To shut down a module safely, either enter the hw-module module stop command or press the OIR button for 5 seconds.
Note The hw-module module stop command is enabled only on the uplink modules of the WS-C4500X-32.
The following example shows what happens if a module is up and you enter the hw-module module stop command:
Switch# hw-module module 2 stop
Proceed with module stop? [confirm]
