Replacing a system fan
Your server supports up to six system fans. This design helps you to avoid significant cooling problems
when a system fan fails.
CAUTION:
Hazardous moving parts. Keep fingers and other body parts away.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Note: Depending on the model, your server might look slightly different from the illustrations in this topic.
To replace a system fan, do the following:
1. Remove all external 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. Prepare your server. See

“Removing the server cover” on page 57.
4. Remove the cooling shroud. See
