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).

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.).
To prevent bodily injury when mounting or servicing this unit in a rack, you must take
special precautions to ensure that the system remains stable. The following guidelines
are provided to ensure your safety:
•
This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
•
When mounting this unit in a partially filled rack, load the rack from the bottom to the top
with the heaviest component at the bottom of the rack.
•
If the rack is provided with stabilizing devices, install the stabilizers before mounting or
servicing the unit in the rack.
•
Slide rail mounted equipment is not to be used as a shelf or a work space.
