The Avaya Multiservice switches are equipped with diagnostics to:
■
Monitor the status of the Primary switch controller.
■
Monitor the status of a Active element.
■
Monitoring of Health Check status messages sent between
the Active and Standby supervisors.
If the Active supervisor fails, the Standby supervisor assumes
supervisor operation. Information about a failed Supervisor (CPU)
displays in the CPU Redundancy Status Dialog Box window.
