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.
