3.3 Audible
Alarm
3.3.1 Overview
Different controller environmental and operational parameters (such
as temperature and voltage) 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 product 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, he/she must read the error message on the LCD keypad panel,
SANWatch Enclosure View, 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.
WARNING!
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.
