Rack Precautions
• Ensure that the leveling jacks on the bottom of the rack are fully extended to
• In single rack installations, stabilizers should be attached to the rack.
• In multiple rack installations, the racks should be coupled together.
• Always make sure that the rack is stable before extending a component from
the rack.
• Only one chassis should be extended from the rack at a time. Extending two or
more chassis simultaneously may cause the rack to become unstable.
• When initially installing the server to a rack, test that the rail locking tabs engage
to prevent the server from being overextended. Have a rack lift in place as a
precaution in case the test fails.
• In any instance of pulling the system from the rack, always use a rack lift and
follow all associated safety precautions.
General Server Precautions

work upward.
• 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.

touching them.
• Always keep the rack's front door and all panels and components on the servers
closed when not servicing to maintain proper cooling.
