WARNING:
Figure 10-5. Switch Fabric Status Dialog Box
If a redundant controller is installed in the switch and enabled, the switch
resets and the redundant controller automatically takes over the operation of
the failed Primary controller.
To replace the failed Primary controller:
1. Disable redundant hardware.
2. Copy the running config to the startup config.
3. Synchronize if you have redundant supervisor modules.
4. Power off the switch power supplies.
To avoid bodily harm and equipment damage, you must power off the
switch before you remove switch controllers or elements.
5. Replace the failed controller.
6. Power on the switch power supplies and login.
