5-4 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.
•
You should extend only one component at a time - extending two or more si-
multaneously 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 upwards.
•
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 plug hard drives and power supply modules to cool before touch-
ing them.
•
Always keep the rack's front door and all panels and components on the servers
closed when not servicing to maintain proper cooling.
