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.
