Determine Which Fan Module Is Faulty
View the following LEDs, which are lit when a fan fault is detected.
■
Fan (FAN) Fault LED on the front of the server. See “Front Panel Components” on page 11.
■
Fan Fault LED on or adjacent to the faulty fan. See “Fan Module LEDs” on page 70.
Each fan contains an LED. When the Service Required LED is lit, a fault has occurred on
that fan module.
Note - The front and rear panel Service Required LEDs are also lit when the server detects a
fan fault. The Server Overtemp LED might also light if a fan fault causes an increase in server
operating temperature.

Remove a Fan Module
Caution - While the fans provide some cooling redundancy, if a fan module fails, replace it as
soon as possible to maintain server availability. When you remove one of the fan modules, you
must replace it within 30 seconds to prevent overheating of the server.
Caution - The fan module contains hazardous moving parts. Unless the power to the server
is completely shut down, replacing the fan module is the only service permitted in the fan
compartment.
You can perform this procedure while the server is running. See “Component Service
Categories” on page 43 for more information about hot-service procedures.
