Chapter 6 Rack Installation
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating tempera-
ture 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 tempera-
ture (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 connec-
tions other than the direct connections to the branch circuit (i.e. the use of power
strips, etc.).
