Temperature Requirements - HP ProLiant DL145 User Manual

HP servers draw in cool air through the front door and expel warm air through the rear door.
Therefore, the front and rear rack doors must be adequately ventilated to allow ambient room
air to enter the cabinet, and the rear door must be adequately ventilated to enable the warm air
to escape from the cabinet.
The 9000 and 10000 Series racks provide proper server cooling from flow-through
perforations in the front and rear doors that provide 64 percent open area for ventilation.

Temperature Requirements

To ensure continued safe and reliable equipment operation, install or locate the system in a
well-ventilated, climate-controlled environment.
The maximum recommended ambient operating temperature (TMRA) for most server
products is 35°C (95°F). The temperature in the room where the rack is located must not
exceed 35°C (95°F).

CAUTION: To prevent improper cooling and damage to the equipment, do not block the
ventilation openings.
CAUTION: When using a Compaq branded 7000 Series rack, you must install the high
airflow rack door insert [P/N 327281-B21 (42U) and P/N 157847-B21 (22U)] to provide proper
front-to-back airflow and cooling.
CAUTION: If a third-party rack is used, observe the following additional requirements to
ensure adequate airflow and to prevent damage to the equipment:
•
Front and rear doors: If the 42U server rack includes closing front and rear doors, you
must allow 5,350 sq cm (830 sq in) of holes evenly distributed from top to bottom to
permit adequate airflow (equivalent to the required 64 percent open area for ventilation).
•
Side: The clearance between the installed rack component and the side panels of the
rack must be a minimum of 7 cm (2.75 in).
CAUTION: To reduce the risk of damage to the equipment when installing third-party options:
•
Do not permit optional equipment to impede airflow around the server or to increase the
internal rack temperature beyond the server or to increase the internal rack temperature
beyond the maximum allowable limits.
•
Do not exceed the manufacturer's recommended ambient operating temperature (TMRA).
