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 threshold is
exceeded, an audible alarm will automatically be triggered. The
thresholds are default threshold values and can be adjusted. To see
how to change the values, please refer to the firmware Operation
Manual on the CD that came with your system.
The alarm will also be triggered when an active component within the
subsystem fails. If the subsystem manager is onsite and hears an
alarm, the manager must read the error message on the LCD keypad
panel, RAIDWatch session, or a PC terminal to determine what has
triggered the alarm. After determining what has occurred, the
manager must take appropriate actions to rectify the problem.
If an alarm is triggered it is necessary for you to determine the
cause of the problem. If the audible alarm is ignored and the
problem is not rectified, unexpected damages may ensue.
