Replacing a system fan

Attention: Do not open your server or attempt any repair before reading and understanding “Safety information” on page iii and “Guidelines” on page 69.

This topic provides instructions on how to replace a system fan.

Your server supports six hot-swap system fans with redundancy, which means that five system fans can provide adequate cooling while the extra one serves as a redundant system fan. This design helps you to avoid significant cooling problems when a system fan fails and you can replace a hot-swap system fan without turning off the server.

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.
