Audible Alarm
An 80db audible alarm, which is controlled by the RAID firmware, is mounted on the
RAID controller to indicate any of the following events:
•
State of controller upon boot-up
•
Change in the normal state of the array
•
Change of controller environmental status (during normal operation)
•
Failure of hardware that the controller manages
If the cause of the event is resolved and/or removed, the audible alarm will cease. You can
also turn off the audible alarm manually through ICPCON or ICP RAID Navigator. If you
use these management tools to silence the alarm, it will only be disabled for the current
event and will be ready to sound again at the next event.

Silencing the Audible Alarm in ICPCON
