Installing the Server in a Rack
Temperature Requirements
To be sure of continued safe and reliable operation of the equipment, install the
system in a well-ventilated, climate-controlled environment.
The HP 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 should not exceed 35° C (95° F).
The operating temperature inside the rack will always be higher than the room
temperature and is dependent on the configuration of equipment in the rack. The
TMRA for each piece of equipment should be checked before installation. The
maximum internal rack temperature for the configuration should not exceed the
values shown in Table 2-1.

rack-mountable ProLiant DL740 servers or increase the internal rack
temperature beyond the HP specified maximum rating.
•
Be sure that the Manufacturer’s TMRA for the optional equipment is not
exceeded when the equipment is installed in the rack.
