Dell20PowerEdge R210 II Technical Guide5.4 Environmental SpecificationsThe airborne contaminant level is class G2 or lower as defined by ISA-S71.04-1985.Table 4 lists the environmental specifications for the R210 II.Table 4. Environmental SpecificationsSpecification Operating Requirements Non-Operating RequirementsTemperature Ranges(for altitude ≤ 900m or 2952.75ft)10°C to 35°C(50°F to 95°F) -40°C to 65°C(-40°F to 149°F)Temperature Ranges(for altitude > 900m or 2952.75ft)10°C to T1°C(50°F to T2°F)Temperature Gradient(maximum per 60 minutes) 10°C 20°CHumidity Percent Ranges(noncondensing)20% to 80%(maximum wet bulbtemperature = 29°C)5% to 95%(maximum wet bulbtemperature = 38°C)Humidity Gradient(maximum per 60 minutes) 10% 10%Altitude RangesLow Limits -50ft(-15.2m)-50ft(-15.2m)High Limits 10,000ft(3048m)35,000ft(10,668m)1Use the formulas in Figure 9 to calculate the maximum operating temperature (in °C) for a given altitude. Usethe first formula if the altitude is stated in meters; use the second formula if the altitude is stated in feet.2Use the formulas in Figure 10 to calculate the maximum operating temperature (in °F) for a given altitude.Use the first formula if the altitude is stated in meters; use the second formula if the altitude is stated in feet.Figure 9.
