For additional information aboutenvironmental measurements for specific system configurations, seeDell.com/environmental_datasheets.Table 26. Environmental specificationsFresh Air: temperature, humidity, altitude de-ratingContinuousoperation10°C to 35°C (50°F to 95°F) at 10% to 80% relative humidity with 26°C (78.8°F) maximumdew point (maximum wet bulb temperature). De-rate maximum allowable dry bulbtemperature at 1°C per 300m above 950m (1°F per 547 ft above 3117 ft).ExpandedoperationWhen operating in the expanded temperature range, system performance may be impacted,and ambient temperature warnings may be reported on the LCD and in the System EventLog.≤ 10% of annual operating hours: 5°C to 10°C and 35°C to 40°C (with no direct sunlight onthe equipment) at 5% to 85% relative humidity with 26°C dew point (maximum wet bulbtemperature). Outside the standard operating temperature (10°C to 35°C), the system canoperate down to 5°C or up to 40°C for a maximum of 10% of its annual operating hours. Fortemperatures between 35°C and 40°C (95°F to 104°F), de-rate maximum allowable dry bulbtemperature by 1°C per 175m above 950m (1°F per 319 ft above 3117 ft).≤ 1% of annual operating hours: –5°C to 5°C and 40°C to 45°C (with no direct sunlight onthe equipment) at 5% to 90% relative humidity with 26°C dew point (maximum wet bulbtemperature). Outside the standard operating temperature (10°C to 35°C), the system canoperate down to –5°C or up to 45°C for a maximum of 1% of its annual operating hours. Fortemperatures between 40°C and 45°C (104°F to 113°F), de-rate maximum allowable dry bulbtemperature by 1°C per 125m above 950m (1°F per 228 ft above 3117 ft).Expanded operation restrictions: No cold startup below 5°C Maximum altitude for the operating temperature must be 3050m (10,000ft) Not supported:— Peripheral cards not qualified by Dell— Peripheral cards greater than 25W— PCIe SSD drives— GPU cards— Express flash— LRDIMM— Non-redundant PSU configurationsTemperatureOperating See Fresh Air for temperature informationStorage –40°C to 65°C (–40°F to 149°F) with a maximum temperature gradation of 20°C per hourRelative humidityOperating See Dell Fresh Air for relative humidity informationStorage 5% to 95% at a maximum wet bulb temperature of 33°C (91°F); atmosphere must be non-condensing at all timesMaximum vibrationOperating 0.26 Grms at 5Hz to 350Hz in all orientations
