When installing your Compaq RA4000 in a rack, certain temperature
standards and power requirements must be met.
The following requirements must be considered when deciding where to install
your rack:
■ Clearance in the front of the rack should be a minimum of 25 inches for
the front door to open all the way and for adequate airflow.
■ Clearance in the back of the rack should be a minimum of 30 inches to
allow for servicing and for adequate airflow.
■ Clearance on each side should be a minimum of 15 inches to allow for
servicing the power supply.
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.
■ The power load needs to 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 power strips are used, the load should not exceed 80 percent of the
power strips marked electrical current rating.
