Standard operating temperature Specications
Continuous operation (for altitude less than 950 m or 3117
ft)
10–35°C (50–95°F) with no direct sunlight on the equipment.
Expanded operating temperature
Table 29. Expanded operating temperature specications
Expanded operating temperature Specications
Continuous operation 5°C–40°C at 5% to 85% RH with 29°C dew point.
NOTE: Outside the standard operating temperature
(10°C–35°C), the system can operate continuously in
temperatures as low as 5°C and as high as 40°C.
For temperatures 35°C– 40°C, derate maximum allowable
temperature by 1°C per 175 m (1°F per 319 ft) above 950 m (3,1171
ft).
≤ 1% of annual operating hours -5°C–45°C at 5% to 90% RH with 29°C dew point.
NOTE: Outside the standard operating temperature
(10°C–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 40°C– 45°C, derate maximum allowable
temperature by 1°C per 125 m (1°F per 228 ft) above 950 m (3.117
ft).
NOTE: When operating in the expanded temperature range, the performance of the system may be impacted.
NOTE: When operating in the expanded temperature range, ambient temperature warnings may be reported on the System
Event Log.
Expanded operating temperature restrictions
• Do not perform a cold startup of the system below 5°C.
• The operating temperature specied is for a maximum altitude of 950 m for Fresh Air cooling.
• Two redundant power supply units are required.
• Cooling redundancy is not supported due to single fan only in system.
• Support up to 80 W processor.
• One system fan is required.
• Non-Dell qualied peripheral cards and/or peripheral cards greater than 25 W are not supported.
• GPU is not supported.
