Airflow Requirements

The Compaq RA4100 draws cool air in through the front door and exhausts
warm air out through the rear of the server. Therefore, the front door of the
rack must be adequately ventilated to allow ambient room air to enter the
cabinet, and the rear door must be adequately ventilated to allow the warm air
to escape from the cabinet. Do not block the ventilation apertures.
Rack Internal Temperature Maximums
CAUTION: To reduce the risk of damage to the equipment when installing third-
party options:
I
Make sure that the options equipment does not impede airflow to the
Compaq RA4100 or increase the internal rack temperature beyond the
Compaq specified maximum rating.
I
Make sure that the Manufacturer's Maximum Recommended Ambient
Operating Temperature of the option equipment is not exceeded when
installed in the rack.
CAUTION: If a third-party rack is used, the following minimum requirements
should be observed to ensure adequate airflow and to prevent damage to the
equipment:
I
Front: The front door must have a minimum of 120 square inches of
unrestricted ventilation openings distributed evenly over the surface of the
