The status of each fan module is displayed by a bi-color LED. These six status LEDs are located on the chassis frame to the right of the fan module bay. The LEDs are labeled with numbers that correspond to fan module labels on the midwall. When the fault manager reports a failed fan module, use the status LEDs to learn the number of the faulty fan module and use the fan locating label on the midwall to identify the fan module.

When a fan module fault is detected, the front and rear panel Service Required LEDs also turn on.
If the fan fault produces an over temperature condition, the system Overtemp LED will turn on and an error message will be logged and displayed on the system console.
