Replacing the Primary Controller

If a Primary controller fails, notification is provided by:

• An event log message
• An error message that displays in the Switch controller field.

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.

WARNING: To avoid bodily harm and equipment damage, you must power off the switch before you remove switch controllers or elements.

7. Enable the redundant hardware (see “Enabling Redundant Hardware” earlier in this chapter).
8. Re-select Switch Fabric from the System > Configuration group on the Web Agent window. The Switch Fabric Status dialog box re-displays with the Switch Controller field displaying:
