Temperature Requirements
For safe and reliable operation of equipment, locate the system in a well-ventilated,
climate-controlled environment.
The HP Maximum Recommended Ambient Operating Temperature (T
MRA
) for most
server products is 95°F (35°C). Therefore, the temperature in the room where the
rack is located should not exceed 95°F (35°C).
The operating temperature inside the rack is always higher than the room
temperature, and is dependent on the configuration of equipment in your rack. Check
the T
MRA
for each piece of equipment before installation.
The maximum internal rack temperature for your configuration should not exceed the
values in the following table.

CAUTION:
To reduce the risk of damage to the equipment when installing
third-party options:
•
Make sure that the option equipment does not impede airflow to the
rack-mountable products already installed in the rack, nor increase the internal
rack temperature beyond the maximum rating specified by HP.
•
Make sure that the manufacturer’s Maximum Recommended Ambient Operating
Temperature for the option equipment is not exceeded when the option
equipment is installed in a HP rack.
