Deactivating the Control Module

Chapter 13: Hot Swapping Line Cards and Control Modules

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 SSR, and insert another Control Module or line card in the slot.

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 SSR. 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 15 shows the location of the Offline LED and Hot Swap button on a Control Module.

Removing the Control Module

To remove a Control Module from the SSR:

1.Make sure that none of the LEDs on the Control Module are lit.

2.Loosen the captive screws on each side of the Control Module.

3.Carefully remove the Control Module from its slot in the SSR chassis.
