Unpacking the System and Choosing an Operating Location

Rack Mounting Considerations

Use the guidelines in the following subsections to properly install, use and maintain a server in a

rack.

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 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).

Reduced Airflow

Equipment should be mounted into a rack so that the amount of airflow required for safe operation

is not compromised.

Mechanical Loading

Equipment should be mounted into a rack so that a hazardous condition does not arise due to

uneven mechanical loading.

Circuit Overloading

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 overcurrent protection and

power supply wiring. Appropriate consideration of equipment nameplate ratings should be used

when addressing this concern.

Reliable Ground

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.).
