Expanded operating temperatureTable 32. Expanded operating temperature specificationsExpanded operating temperature SpecificationsContinuous operation 5°C to 40°C at 5% to 85% RH with 29°C dew point.NOTE: Outside the standard operating temperature(10°C to 35°C), the system can operate continuouslyin temperatures as low as 5°C and as high as 40°C.For temperatures between 35°C and 40°C, de-ratemaximum allowable temperature by 1°C per 175 m above950 m (1°F per 319 ft).< 1% of annual operating hours –5°C to 45°C at 5% to 90% RH with 29°C dew point.NOTE: Outside the standard operating temperature(10°C to 35°C), the system can operate down to –5°Cor up to 45°C for a maximum of 1% of its annualoperating hours.For temperatures between 40°C and 45°C, de-ratemaximum allowable temperature by 1°C per 125 m above950 m (1°F per 228 ft).NOTE: When operating in the expanded temperature range, system performance may be impacted.NOTE: When operating in the expanded temperature range, ambient temperature warnings maybereported in the System Event Log.Expanded operating temperature restrictions• Do not perform a cold startup below 5°C.• The operating temperature specified is for a maximum altitude of 3050 m (10,000 ft).• 160 W or higher wattage processor is not supported.• Redundant power supply units are required.• Non-Dell qualified peripheral cards and/or peripheral cards greater than 25 W are not supported.• The 3.5-inch hard drive chassis supports a maximum of 120 W processor.• The 2.5-inch hard drive chassis supports a maximum of 145 W processor.• Only SSDs are allowed in the hard drive slots at the back of the 3.5-inch hard drive chassis.• Mid drive configurations, eight 3.5-inch and eighteen 1.8-inch SSD configurations are not supported.• GPU is not supported• Tape backup unit (TBU) is not supported.39
