Replacing the front fan assembly
Attention: Do not open your server or attempt any repair before reading and understanding “Safety information”
on page iii and “Guidelines” on page 39.
Depending on the model type, your server might have a front fan assembly installed. This topic provides
instructions on how to replace the front fan assembly.
To replace the front fan assembly, do the following:
1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all
power cords from electrical outlets and disconnect all cables that are connected to the server.
2. Remove the server cover. See “Removing the server cover” on page 41.
3. Remove the front bezel. See “Removing and reinstalling the front bezel” on page 42.
4. Disconnect the front fan assembly cable from the power fan connector on the system board. See
“Locating parts on the system board” on page 17.
5. The front fan assembly is attached to the chassis by four rubber mounts. Remove the front fan assembly
by breaking or cutting the rubber mounts and gently pulling the front fan assembly out of the chassis.
Note: The new front fan assembly will have four new rubber mounts attached.
