Installing the Fan Module
NOTE: Note the direction of airflow on the fan modules and ensure that the fan
modules are oriented in the correct direction while installing.
Align the slots on the fan module with the slots on the fan assembly such that
the labelled side faces the back of the system. Secure the fan module to the
fan assembly using the screws. See Figure 3-23.
Backplane
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 support team. Damage due to servicing that is not authorized by Dell is not
covered by your warranty. Read and follow the safety instructions that came
with the product.
Removing the Backplane
1 Turn off the system, including any attached peripherals, and disconnect
the system from its electrical outlet.
2 Open the system. See "Opening the System" on page 58.

CAUTION: To prevent damage to the drives and backplane, you must remove the
hard drives from the system before removing the backplane.
CAUTION: You must note the number of each hard drive and temporarily label
them before removal so that you can replace them in the same locations.

page 54.
