Audible

Alarm

The subsystem has a novel approach to stabilizing the temperature within

the chassis:

When temperature sensors detect an elevated temperature reading

or the failure of any cooling fan/power supply, firmware will

instruct the remaining cooling fans to operate at a high speed. Once

the ambient temperature falls back within the safe range or the fault

condition is corrected, cooling fans will resume the low rotation

speed.

4.5 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.

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.

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.

4.5.1 Failed Devices

If any of the following devices fail, the audible alarm will be triggered:

•

RAID controller module

•

Cooling module

•

PSU

•

BBU

•

Hard drive

•

Sensors and presence detection circuits
