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 between 35°C-40°C, de-rate maximum allowable temperature by 1°C per 175 m above 950 m (1°F per 319 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 between 40°C and 45°C, de-rate maximum allowable temperature by 1°C per 125 m above 950 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 may be reported on the LCD panel and 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). • 150 W/8 C, 165 W/12 C and higher wattage processor(TDP>165 W) are not supported. • Redundant power supply unit is required. • Non-Dell qualified peripheral cards and/or peripheral cards greater than 25 W are not supported. • NVDIMM-Ns are not supported. 12 Technical specifications
