Dell EMC PowerEdge R440 - Standard Operating Temperature; Expanded Operating Temperature

Particulate contamination Specications
Corrosive dust
• Air must be free of corrosive dust.
• Residual dust present in the air must have a deliquescent point less than
60% relative humidity.
NOTE: This condition applies to data center and non-data center
environments.
Table 28. Gaseous contamination specications
Gaseous contamination Specications
Copper coupon corrosion rate <300 Å/month per Class G1 as dened by ANSI/ISA71.04-1985.
Silver coupon corrosion rate <200 Å/month as dened by AHSRAE TC9.9.
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
Standard operating temperature

Standard operating temperature Specications
Continuous operation (for altitude less than 950 m or 3117
ft)
10°C to 35°C (50°F to 95°F) with no direct sunlight on the equipment.
Expanded operating temperature

specications
Expanded operating temperature Specications
Continuous operation 5°C to 40°C at 5% to 85% RH with 29°C dew point.
NOTE: Outside the standard operating temperature (10°C to
40°C), the system can operate continuously in temperatures as low
as 5°C and as high as 40°C.
For temperatures between 35°C and 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 to 45°C at 5% to 90% RH with 29°C dew point.
NOTE: Outside the standard operating temperature (10°C to
40°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.
