Dell EMC VxRail P470 - Standard Operating Temperature; Expanded Operating Temperature

Particulate contamination Specifications
NOTE: Air entering the data center must have MERV11 or
MERV13 filtration.
Conductive dust Air must be free of conductive dust, zinc whiskers, or other
conductive particles.
NOTE: This condition applies to data center and non-data
center environments.
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 22. Gaseous contamination specifications
Gaseous contamination Specifications
Copper coupon corrosion rate <300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.
Silver coupon corrosion rate <200 Å/month as defined by AHSRAE TC9.9.
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
Standard operating temperature
The standard operating temperature for altitude less than 950 meters or 3117 feet ranges from 10°C to 35°C (50°F to 95°F) with no
direct sunlight on the equipment.
Expanded operating temperature
Table 23. Expanded operating temperature specifications
Expanded operating temperature Specifications
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 35°C), the appliance 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 35°C), the appliance can operate down to –5°C or up
to 45°C for a maximum of 1% of its annual operating
hours.
