Rack Precautions
The following guidelines help insure your rack systems proper operation:
• Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with
the full weight of the rack resting on them.
• In single rack installation, stabilizers should be attached to the rack.
• In multiple rack installations, the racks should be coupled together.
• Always make sure the rack is stable before extending a component from the rack.
• You should extend only one component at a time - extending two or more simultaneously
may cause the rack to become unstable.
• Always keep the rack's front door and all panels and components on the servers closed when
not servicing to maintain proper cooling.
Server Precautions
Review the electrical and general safety precautions in Chapter 1.
Determine the placement of each component in the rack before you install the rails.
Install the heaviest server components on the bottom of the rack first, and then work up.
For extra protection, use a regulating uninterruptible power supply (UPS) to protect the server
from power surges, voltage spikes and to keep your system operating in case of a power failure.
This is an optional device not provided by SGI with your system.
Allow the hot plug disk drives and power supply modules to cool before touching them. Always
keep the server closed when not servicing to maintain proper cooling.
Make sure all power and data cables are properly connected and not blocking the chassis airflow.
