Particulate contamination
Specifications
•
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.

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 specifications
Table 19. Standard operating temperature specifications
Standard operating temperature
Specifications
Continuous operation (altitudes under 950 m / 3,117 ft)
10°C to 35°C (50°F to 95°F), avoiding direct sunlight
NOTE:
The system supports a maximum 165 W TDP.
Expanded operating temperature specifications
Table 20. Expanded operating temperature specifications
Expanded operating temperature
Specifications
≤10% of annual operating hours
5°C to 40°C (41°F to 104°F), avoiding direct sunlight on the equipment
NOTE:
Outside the standard operating temperature (10°C to
35°C / 50°F to 95°F), the system can operate for a maximum of
10% of its annual operating hours in temperatures as low as 5°C
(41°F) and as high as 40°C (104°F).
For temperatures between 35°C and 40°C (95°F and 104°F), 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 (23°F to 113°F) at 5% to 90% RH with 29°C (84°F) dew
point
NOTE:
Outside the standard operating temperature (10°C to
35°C / 50°F to 95°F), the system can operate down to –5°C
(23°F) or up to 45°C (113°F) for a maximum of 1% of its annual
operating hours.
For temperatures between 40°C and 45°C (104°F and 113°F), de-rate
maximum allowable temperature by 1°C per 125 m above 950 m (1°F per 228
ft).
