Replacing the Primary Controller
If a primary controller fails, you are notified by:
■ A console message
■ An event log message
■ The following error message that displays in the Switch
controller field on the Switch Status dialog box:

If the switch is installed with a redundant controller that has been
enabled, the redundant controller automatically takes over the
operation of the failed primary controller.
To replace the primary controller:

group on the web agent window. The Switch Fabric Status
dialog box opens (Figure7-3).
2. Select No from the Configure Redundant Hardware field
pull-down menu.
3. Click APPLY to disable the primary controller.
4. Power off the switch power supplies.
WARNING

off the switch before you remove switch controllers or elements.
5. Remove the failed primary controller from the switch.
6. Replace with a good primary controller.
7. Power on the switch power supplies and login.
8. Refer to the "Enabling Redundant Hardware" section and
complete the procedure.

group on the web agent window. The Switch Fabric Status
dialog box re-displays with the Switch Controller field
