Cooling Fans

Your system contains four cooling fans, single- or dual-motor depending on

your system configuration. These provide cooling for the processor, PCI cards,

and memory modules. Systems with redundant power supplies also contain

one single-motor fan to provide cooling for the power supplies.

NOTE:

Hot-swap removal or installation of the cooling fans is not supported.

NOTE:

In the event of a problem with a particular fan, the fan number is referenced

by the system’s management software, allowing you to easily identify and replace

the proper fan by noting the fan numbers on the fan assembly.

Removing a Cooling Fan

WARNING:

The cooling fan can continue to spin for some time after the system

has been powered down. Allow time for the fan to stop spinning before removing
it from the system.

WARNING:

Do not attempt to operate the system without the cooling fans.

CAUTION:

Many repairs may only be done by a certified service technician.

You should only perform troubleshooting and simple repairs as authorized in
your product documentation, or as directed by the online or telephone service and
