Chassis Maintenance

For warranty and safety considerations, SGI designates the following chassis components as
customer-replaceable units (CRUs):

•

Power supplies

•

Fans

•

Disk drives

These components are all hot-swappable; that is, you can replace them without powering down
the server. A trained service technician should install and replace all other components.

This chapter describes the following chassis maintenance activities:

•

“Removing and Installing the Front Fan Bezel” on page 23

•

“Removing the Rack Handles” on page 25
