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.
