Expanded operating temperature
Continuous operation
Less than or equal to 1% of annual operating hours
NOTE:
When operating in the expanded temperature range, system performance may be impacted.
NOTE:
When operating in the expanded temperature range, ambient temperature warnings maybe reported on the LCD
panel and in the System Event Log.
Specifications
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.
•
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.
Specifications
<300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.
<200 Å/month as defined by AHSRAE TC9.9.
Specifications
10°C to 35°C (50°F to 95°F) with no direct sunlight on the equipment.
10% to 80% Relative Humidity with 26°C (78.8°F) maximum dew point.
Specifications
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 dry
bulb temperature by 1°C per 175 m above 950 m (1°F per 319 ft).
–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 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).
