Use the guidelines in the following subsections to properly install, use and maintain a server in a
rack.
If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack
environment may be greater than the ambient temperature of the room. Therefore, consideration
should be given to installing the equipment in an environment compatible with the manufacturer's
maximum rated ambient temperature (Tmra).
Equipment should be mounted into a rack so that the amount of airflow required for safe operation
is not compromised.
Equipment should be mounted into a rack so that a hazardous condition does not arise due to
uneven mechanical loading.
Consideration should be given to the connection of the equipment to the power supply circuitry
and the effect that any possible overloading of circuits might have on over-current protection and
power supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
A reliable ground must be maintained at all times. To ensure this, the rack itself should be
grounded. Particular attention should be given to power supply connections other than the direct
connections to the branch circuit (i.e. the use of power strips, etc.).
