4.3
Audible Alarm
Different controller environmental and operational parameters (like temperature, etc.) have
been assigned a range of values between which they can fluctuate. If either the upper or lower
thresholds are exceeded, an audible alarm will automatically be triggered. The alarm will also
be triggered when an active component on the RAID subsystem fails. If the RAID subsystem
manager is onsite and hears an alarm, the manager must read the error message on the LCD
screen or PC terminal to determine what has triggered the alarm. After determining what has
occurred, the RAID subsystem manager must take appropriate actions to rectify the problem.
CAUTION!
If an alarm is triggered it is necessary for you to determine the problem. If the audible alarm is
ignored and the problem is not rectified, unexpected damages may occur.
