Cooling Module LEDs
Each cooling module has two (2) red LEDs on the back. Each LED corresponds to a single fan
in the cooling module. (See Figure 4.7) When the LED is on, it indicates the fan has failed.
When the LED is off, it indicates the fan is functioning properly.
Fig. 4.7 Cooling Module LEDs and Cooling Fan Locations
The RAID subsystem has a novel approach to stabilizing the temperature within the subsys-
tem: When the intelligent sensors on the backplane detect higher temperature, such as high
ambient 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.
