Particulate contamination
Specifications
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.

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
Table 26. Standard operating temperature specifications
Standard operating temperature
Specifications
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.
NOTE: The 2.5-inch hard drive chassis supports a
maximum of 145 W processors.
Expanded operating temperature
Table 27. 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 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.
