Temperature
Continuous
operation
10°C to 35°C at 10% to 80% relative humidity (RH), with 26°C max dew point. De-rate
maximum allowable dry bulb temperature at 1°C per 300m above 900m (1°F per 550 ft).
Expanded
operation
When operating in the expanded temperature range, system performance may be
impacted. When operating in the expanded temperature range, ambient temperature
warnings may be reported on the LCD and in the System Event Log.
≤ 10% of annual operating hours: 5°C to 40°C at 5% to 85% RH with 26°C dew point.
Outside the standard operating temperature (10°C to 35°C), the system can operate down
to 5°C or up to 40°C for a maximum of 10% of its annual operating hours. For
temperatures between 35°C and 40°C, de-rate maximum allowable dry bulb temperature
by 1°C per 175m above 950m (1°F per 319 ft).
≤ 1% of annual operating hours: –5°C to 45°C at 5% to 90% RH with 26°C dew point.
Outside the standard operating temperature (10°C to 35°C), the system can operate down
to –5°C or up to 45°C for a maximum of 1% of its annual operating hours. For
temperatures between 40°C and 45°C, de-rate maximum allowable dry bulb temperature
by 1°C per 125m above 950m (1 °F per 22 ft).
Expanded operation restrictions:
 No cold startup below 5°C
 Maximum altitude for the operating temperature must be 3050m (10,000 ft)
 Express Flash PCIe SSD, GPU, and LRDIMM not supported
 130W (4 core) and 135W processor not supported
 Redundant power supplies required
 Non Dell qualified peripheral cards and peripheral cards greater than 25W not
supported
