Compaq ProLiant DL580 Setup And Installation Manual page 79

Temperature Requirements
To ensure safe and reliable operation of your equipment, install the system in a
well-ventilated, climate-controlled environment.
The Compaq Maximum Recommended Ambient Operating Temperature
(TMRA) for most server products is 95°F (35°C). This means the temperature
in the room where a rack server is located should not exceed this maximum
level.
The operating temperature inside the rack will always be higher than in the
surrounding room. Heat levels depend on the configuration of equipment.
Check the Maximum Internal Rack Temperature for each component before
installation. Temperatures should not exceed those listed in Table 4-1.

CAUTION: To reduce the risk of equipment damage when installing third-party
options:
I
Make sure that optional equipment does not impede airflow to the server
and does not increase the internal rack temperature beyond the
Compaq-specified maximum rating.
I
Make sure the optional equipment does not exceed its Manufacturer's
Maximum Recommended Ambient Operating Temperature when installed
in the rack.
Airflow Requirements
The Compaq ProLiant DL580 server draws cool air in through the front door
and exhausts warm air out the rear. 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 ventilated adequately to allow the warm air to escape from
the cabinet. In both cases, do not block the ventilation apertures.
