10° to 35°C (50° to 95°F) at sea level with an altitude derating of 1.0°C per every 305 m (1.8°F per every 1,000 ft) above sea level to a
maximum of 3,050 m (10,000 ft), no direct sustained sunlight. Maximum rate of change is 20°C/hr​ (36°F/hr). The upper limit and rate of
change may be limited by the type and number of options installed.
System performance during standard operating support might be reduced in the following conditions:
A fan failure occurs.
The server operates above 30°C (86°F).
Extended ambient operating support Extended ambient operating support
For approved hardware configurations, the supported system inlet range is extended to be:
5° to 10°C (41° to 50°F) and 35° to 40°C (95° to 104°F) at sea level with an altitude derating of 1.0°C per every 175 m (1.8°F per
every 574 ft) above 900 m (2,953 ft) to a maximum of 3050 m (10,000 ft).
40°C to 45°C (104°F to 113°F) at sea level with an altitude derating of 1.0°C per every 125 m (1.8°F per every 410 ft) above 900 m
(2953 ft) to a maximum of 3,050 m (10,000 ft).
The approved hardware configurations for this system are listed in the Extended Ambient Temperature Guidelines for Gen11 HPE
