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.
4.3.1
Default Threshold Values
Table 4.7 shows the default threshold values for the RAID subsystem. If any of these values are 
surpassed, the alarm will sound:
The thresholds in Table 4.7 are default threshold values and may be changed.
4.3.2
Failed Devices
If any of the following devices fail, the audible alarm will be triggered:
RAID controller module
Cooling modules
PSU modules
BBU
Hard drives
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.

NOTICE! 
When the temperature exceeds a preset threshold, the controller’s charger circuits will stop 
charging. You will then receive a message that says “Thermal Shutdown/Enter Sleep Mode.” 
When the temperature falls back within normal range, the battery will resume charging.
