For additional information about environmental measurements for specific system configurations, see Dell.com/environmental_datasheets. Table 26. Environmental specifications Fresh Air: temperature, humidity, altitude de-rating Continuous operation 10°C to 35°C (50°F to 95°F) at 10% to 80% relative humidity with 26°C (78.8°F) maximum dew point (maximum wet bulb temperature). De- rate maximum allowable dry bulb temperature at 1°C per 300m above 950m (1°F per 547 ft above 3117 ft). Expanded operation When 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 Event Log. ≤ 10% of annual operating hours: 5°C to 10°C and 35°C to 40°C (with no direct sunlight on the equipment) at 5% to 85% relative humidity with 26°C dew point (maximum wet bulb temperature). 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 (95°F to 104°F), de- rate maximum allowable dry bulb temperature 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 on the equipment) at 5% to 90% relative humidity with 26°C dew point (maximum wet bulb temperature). 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 (104°F to 113°F), de- rate maximum allowable dry bulb temperature 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 Temperature Operating Storage See Fresh Air for temperature information - 40oC to 65oC (- 40oF to 149oF) with a maximum temperature gradation of 20oC per hour Relative humidity Operating See Fresh Air for relative humidity information Storage 5% to 95% at a maximum wet bulb temperature of 33°C (91°F); atmosphere must be condensing at all times Maximum vibration Operating 0.26 Grms at 5Hz to 350Hz in all orientations Storage 1.87 Grms at 10Hz to 500Hz for 15 minutes (all six sides tested) 45 PowerEdge R320 Technical Guide
