6.1 System Buzzer
The system buzzer features are listed below:
1. The system buzzer alarms 1 second when system boots up successfully.
2. The system buzzer alarms continuously when there is error occurred. The alarm will
be stopped after error resolved or be muted.
3. The alarm will be muted automatically when the error is resolved. E.g., when RAID
5 is degraded and alarm rings immediately, user changes / adds one physical disk
for rebuilding. When the rebuilding is done, the alarm will be muted automatically.
