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 (TMRA) 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 TMRA
for each piece of equipment before installation.
The maximum internal rack temperature for your configuration should not exceed the
values in the following table.
Table 2-1: Rack Internal Temperature Maximums
Equipment Included Maximum Internal Rack
Temperature
HP rack-mountable servers 95°F/35°C
HP rack-mountable options 104°F/40°C
HP PDUs 122°F/50°C

specifications
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 or increase the internal
rack temperature beyond the HP specified maximum rating.
• 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.
