2-6 Compaq ProLiant 6400R Setup and Installation Guide Table 2-1 Rack Internal Temperature Maximums Equipment Included Rack-Mountable ProLiant 6400R servers Compaq rack-mountable options Other manufacturers' options Maximum Internal Rack Temperature 50°C (122°F) 40°C (104°F) See other manufacturers' specifications CAUTION: To reduce the risk of damage to the equipment when installing thirdparty options, Ensure that the optional equipment does not impede airflow to the rack-mountable ProLiant 6400R server or increase the internal rack temperature beyond the maximum rating specified by Compaq. Ensure that the manufacturer's maximum recommended ambient operating temperature of the optional equipment is not exceeded when installed in the rack. Airflow Requirements The Compaq ProLiant 6400R server draws cool air in through the front door and exhausts warm air out the rear door. Therefore, the front door of the rack must be adequately ventilated to enable ambient room air to enter the cabinet, and the rear door must be ventilated adequately to enable the warm air to escape from the cabinet. Do not block the ventilation apertures. CAUTION: If a third-party rack is used, observe the following minimum requirements to ensure adequate airflow and prevent damage to the equipment: Front: The rack door should have 120 square inches of holes evenly distributed from top to bottom to permit adequate air flow. Side: The clearance between the installed module and the side panels of the rack should be a minimum of 2.75 inches. Rear: The clearance between the back of the rack and the wall should be a minimum of 30 inches, and the equipment should operate without a rear door. CAUTION: If all the vertical space in the rack is not filled by components, the gaps left change the airflow through the rack and across the components. Cover the gaps with blanking panels.

CAUTION:
To reduce the risk of damage to the equipment when installing third-
party options,
■
Ensure that the optional equipment does not impede airflow to the
rack-mountable ProLiant 6400R server or increase the internal rack
temperature beyond the maximum rating specified by Compaq.
■
Ensure that the manufacturer’s maximum recommended ambient
operating temperature of the optional equipment is not exceeded when
installed in the rack.
Airflow Requirements
The Compaq ProLiant 6400R server draws cool air in through the front door
and exhausts warm air out the rear door. Therefore, the front door of the rack
must be adequately ventilated to enable ambient room air to enter the cabinet,
and the rear door must be ventilated adequately to enable the warm air to
escape from the cabinet. Do not block the ventilation apertures.
CAUTION:
If a third-party rack is used, observe the following minimum
requirements to ensure adequate airflow and prevent damage to the equipment:
■
Front: The rack door should have 120 square inches of holes evenly
distributed from top to bottom to permit adequate air flow.
■
Side: The clearance between the installed module and the side panels of
the rack should be a minimum of 2.75 inches.
■
Rear: The clearance between the back of the rack and the wall should be a
minimum of 30 inches, and the equipment should operate without a rear
door.
CAUTION:
If all the vertical space in the rack is not filled by components, the
gaps left change the airflow through the rack and across the components. Cover
the gaps with blanking panels.
