Detecting a Fan Module Failure
The following LEDs are lit when a fan module fault is detected:
■
Front and rear Service Required LEDs located on each server node
■

The system over-temperature LED for a server node might light if a fan fault causes an increase
in server node operating temperature. See “Server Node Status Indicators” on page 17 for more
information about server node LEDs.
