4.2.7Cooling Module LEDs

Each cooling module has one (1) red LED on the back. The LED corresponds to the single fan in the cooling module. (See Figure 4.6) When the LED is on, it indicates the fan has failed. When the LED is off, it indicates the fan is functioning properly.

The subsystem has a novel approach to stabilizing the temperature within the subsystem:

 

When the intelligent sensors on the backplane detect higher temperature, such as high ambi-

 

ent temperature or the failure of any cooling or PSU module, the system will turn the cooling

 

fans to high speed to extract more heat. Once the ambient temperature cools down to normal

 

or the cooling or PSU modules have been replaced, the cooling fans will return to low speed.

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 PC

 

terminal or RAIDWatch screen 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.

Default Threshold Values

 

Table 4.6 shows the default threshold values for the RAID subsystem. If any of these values are

 

surpassed, the alarm will sound:
