Cabletron Systems SmartSwitch manual Hot Swapping a Switching Fabric Module SSR 8600 only

Chapter 2: Hot Swapping Line Cards and Control Modules

Installing the Control Module

To install a new Control Module or line card into the slot:

Note: You can install either a line card or a Control Module in slot CM/1, but you can install only a Control Module in slot CM.

1.Slide the Control Module or line card all the way into the slot, firmly but gently pressing it fully in place to ensure that the pins on the back of the card are completely seated in the backplane.

Note: Make sure the circuit card (and not the metal plate) is between the card guides. Check both the upper and lower tracks.

2.Tighten the captive screws on each side of the Control Module or line card to secure it to the chassis.

On a line card, the Online LED lights, indicating it is now active.

On a secondary Control Module, the Offline LED lights, indicating it is standing by to take over as the primary Control Module if necessary.

Hot Swapping a Switching Fabric Module (SSR 8600 only)

The SSR 8600 has slots for two Switching Fabric Modules. While the SSR 8600 is operating, you can install a second Switching Fabric Module. If two Switching Fabric Modules are installed, you can hot swap one of them.

When you remove one of the Switching Fabric Modules, the other goes online and stays online until it is removed or the SSR 8600 is powered off. When the SSR 8600 is powered on again, the Switching Fabric Module in slot “Fabric 1”, if one is installed there, becomes the active Switching Fabric Module.

Warning: You can only hot swap a Switching Fabric Module if two are installed on the SSR 8600. If only one Switching Fabric Module is installed, and you remove it, the SSR 8600 will crash.

The procedure for hot swapping a Switching Fabric Module is similar to the procedure for hot swapping a line card or Control Module. You deactivate the Switching Fabric Module, remove it from the SSR, and insert another Switching Fabric Module in the slot.

Note: You cannot deactivate the Switching Fabric Module with the system hotswap command.

To deactivate the Switching Fabric Module:

1.Press the Hot Swap button on the Switching Fabric Module you want to deactivate.
