Caution: If a fan has failed, replace the fan as soon as possible to avoid
over-heating and damaging the server.
Procedure
1. Remove the front fascia (and the fan guard plate), see Bezel removal on
page 50 for more information. The fan assemblies will then be visible.
2. Identify the fan to be replaced. Fans are labeled on the chassis, and are
numbered 1 to 3, with fan 1 on the left and fan 3 on the right.
3. Disconnect the fan lead from its connector by pressing down on the small
retaining clip, as shown next.

4. Remove the upper fan retention bracket and place it in a safe location.
Note that the upper fan retention bracket helps to hold all three fan
assemblies in position.

5. For each fan assembly you are replacing, remove the lower fan retention
bracket and place it in a safe location.
6. Remove the faulty fan assembly, and put the new fan assembly into
place. Make sure to:
• Fit the new fan assembly in the same orientation as the old fan
assembly (the arrow indicating the direction of airflow must point into
the server).
• Align the fan lead and its protective sleeve in the space allotted for it
on the bottom right side of the fan assembly mounting area.
• Fit the fan assembly between the left and right mounting guides.
