Hot Swapping a Secondary Control Module Hot Swapping Line Cards and Control Modules
Warning You can only hot swap an inactive Control Module. You should never remove
the active Control Module from the RS. Doing so will crash the system.
The procedure for hot swapping a Control Module is similar to the procedure for hot swapping a line card. You must
deactivate the Control Module, remove it from the RS, and insert another Control Module or line card in the slot.
4.4.1 Deactivating the Control Module
To deactivate the Control Module:
1. Determine which is the secondary Control Module.
Control Modules can reside in slot CM or slot CM/1 on the RS. Usually slot CM contains the primary Control
Module, and slot CM/1 contains the secondary Control Module. On the primary Control Module, the Online LED
is lit, and on the secondary Control Module, the Offline LED is lit.
Note The Offline LED on the Control Module has a different function from the Offline
LED on a line card. On a line card, it means that the line card has been deactivated.
On a Control Module, a lit Offline LED means that it is standing by to take over
as the primary Control Module if necessary; it does not mean that the Control
Module has been deactivated.
2. Press the Hot Swap button on the secondary Control Module.
When you press the Hot Swap button, all the LEDs on the Control Module (including the Offline LED) are
deactivated.
Figure 4-2 shows the location of the Offline LED and Hot Swap button on a Control Module.

You can also use the
system hotswap out
command in the CLI to deactivate the Control Module. For example, to
deactivate the secondary Control Module in slot CM/1, enter the following command in Enable mode:
rs# system hotswap out slot 1
