Fan Module Status LEDs
Each fan module contains a pair of LEDs, which are visible when you open the fan
compartment access door. The following table describes the status LEDs located on
the fan modules.
The front and rear panel Service Required LEDs are also lit if the system detects a fan
module fault.
If the fan fault causes an over temperature condition to occur, the system Overtemp
LED will turn on and an error message will be logged as well as displayed on the
system console.
