Rack Precautions
•
Ensure that the leveling jacks on the bottom of the rack are extended to the floor so that
the full weight of the rack rests on them.
•
In single rack installations, stabilizers should be attached to the rack. In multiple rack in-
stallations, the racks should be coupled together.
•
Always make sure the rack is stable before extending a server or other component from
the rack.
•
You should extend only one server or component at a time - extending two or more simul-
taneously may cause the rack to become unstable.
Server Precautions

Review the electrical and general safety precautions in
•
Determine the placement of each component in the rack before you install the rails.
•
Install the heaviest server components at the bottom of the rack first and then work your

•
Use a regulating uninterruptible power supply (UPS) to protect the server from power
surges and voltage spikes and to keep your system operating in case of a power failure.

When not servicing, always keep the front door of the rack and all covers/panels on the
servers closed to maintain proper cooling.
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating temperature of
the rack environment may be greater than the room's ambient temperature. Therefore,
consideration should be given to installing the equipment in an environment compatible with
the manufacturer’s maximum rated ambient temperature (TMRA).
