Optimum Environment

Specific requirements for space, power, temperature, and airflow must be met to
provide optimum performance with minimum maintenance for your rack
environment.

Space Requirements

When deciding where to place your rack:
•
At least 122 cm (48 inches) of clearance is needed all the way around the pallet
and above the rack to allow the removal of packing materials.
•
At least 86 cm (34 inches) of clearance is needed in front of the rack to allow the
door to open all the way.
•
At least 75 cm (30 inches) of clearance is needed in the rear of the rack to
provide access to components.
•
At least 38 cm (15 inches) of clearance is needed around a power supply to
facilitate servicing.

Power Requirements

WARNING: To reduce the risk of personal injury, fire, or damage to the
equipment, do not overload the AC supply branch circuit that provides power
to the rack. Consult the electrical authority having jurisdiction over your
facility wiring and installation requirements.
When planning for power distribution requirements for your rack configuration:
•
The power load must be balanced between available AC supply branch circuits.
•
The overall system AC current load must not exceed 80 percent of the branch
circuit AC current rating.
•
If a UPS is used, the load should not exceed 80 percent of the marked electrical
current rating of the UPS.
