Replacing a system fan
The system has five high-performance PWM fans to provide the
cooling for the system. Fan speed may be controlled by a setting in
BIOS (see Chapter 4).
To replace a fan module:
1 Perform the pre-installation instructions described on page 22.
Warning! The system fans become very hot when the system is on.
Allow it to cool off first before handling.
2 Remove the top chassis cover while the system is still running to
determine which of the fans has failed.
3 Remove the fan module.
(1) Disconnect the fan cable.
(2) Pull the fan up and away from the chassis.
4 Install the new fan module.
(1) To install a new fan module into FAN2, rotate the fan module
90 degrees.
