6-4 Warnings and Precautions
Rack Precautions
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 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.
General Server Precautions
Review the electrical and general safety precautions that came with the com-
•
ponents you are adding to your chassis.
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 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.
Allow the hot-swappable hard drives and power supply modules to cool before
•
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.
