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.
The Online LED goes out and the Offline LED lights. Figure 4 shows the location of the
Offline LED and Hot Swap button on a Switching Fabric Module.
