This procedure describes how to identify a faulty fan module.
Fan Module (FAN) Fault LED on the front of the server (refer to Front Components).
Fan Fault LED on or adjacent to the faulty fan module (refer to the following illustration). Each fan module contains an LED. When the amber Service Required LED is lit, a fault has occurred on that fan module.
The following table describes the status LEDs located on the fan modules.
Note - The front and rear panel Service Action Required LEDs are also lit when the system detects a fan module fault. The system Overtemp LED might also light if a fan fault causes an increase in system operating temperature.
