Standard operating temperature
Table 18. 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.
Humidity percentage range
10% to 80% Relative Humidity with 26°C (78.8°F) maximum dew point.
Expanded operating temperature
Table 19. 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 dry
bulb temperature by 1°C per 175 m above 950 m (1°F per 319 ft).
Less than or equal to 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 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).
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.
