For additional information about environmental measurements for specific system configurations,see Dell.com/environmental_datasheets.Table 24 details the environmental specifications for the M620.Fresh 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: Maximum 95W processor is supported. Dell PERC H710 and H710P cards are not supported in dual-processor configurations. When populating the blade slots in the enclosure with only PowerEdge M620 blades:- Dual-processor blade servers with PERC H310 cards cannot be mixed with single-processor blades.- To support a PERC H310 card in a dual-processor configuration, the blade slots inthe M1000e enclosure must be installed with M620 blades or a combination ofblade blanks and M620 blades.The PowerEdge M620 blades must be installed with 97 mm wide heat sinks. Non Dell qualified peripheral cards and/or peripheral cards greater than 25W are notsupported.TemperatureOperating See Fresh Air for temperature informationStorage –40oC to 65oC (-40oF to 149oF) with a maximum temperature gradation of 20oC per hourRelative humidityOperating See Fresh Air for relative humidity informationStorage 5% to 95% at a maximum wet bulb temperature of 33°C (91°F); atmosphere must becondensing at all times
