Fan Modules

The Fan Modules and Fan Module LEDs of the storage controller are shown in the following
figure. The following LEDs are lit when a fan module fault is detected:

■

Front and rear Service Action Required LEDs

■

Fan Module Service Action Required (TOP) LED on the front of the server

■

Fan Fault LED on or adjacent to the faulty fan module

The system Overtemp LED might light if a fan fault causes an increase in system operating
temperature.
