Operating temperature
derating Specifications
Up to 35°C (95°F) Maximum temperature is reduced by 1°C/300 m
(1°F/547 ft), above 950 m (3,117 ft).
35–40 °C (95–104 °F) Maximum temperature is reduced by 1°C/175 m
(1°F/319 ft), above 950 m (3,117 ft).
40–45 °C (104 °F–113 °F) Maximum temperature is reduced by 1°C/125 m
(1°F/228 ft), above 950 m (3,117 ft).
Standard operating temperature
The standard operating temperature for altitude less than 950 m or 3117 ft ranges
10 °C–35°C with no direct sunlight on the equipment.
Note
The 2.5-inch hard drive chassis supports a maximum of 145 W processors.
Table 31 Standard operating temperature specifications
Standard operating temperature Specifications
Continuous operation (for altitude less
than 950 m or 3117 ft) 10 °C–35°C (50 °F–95°F) with no direct sunlight
on the equipment.
Expanded operating temperature
When the system is in continuous operation, the expanded operating temperature
ranges 5 °C–40°C at 5% to 85% RH with 29°C dew point. NOTE: Outside the
standard operating temperature (10 °C–35°C), the system can operate continuously
in temperatures as low as 5°C and as high as 40°C. For temperatures 35 °C – 40°C,
derate maximum allowable temperature by 1°C per 175 m above 950 m (1°F per 319
ft). When the system is operating at < 1% of annual operating hours, the expanded
operating temperature is –5 °C–45°C at 5% to 90% RH with 29°C dew point. NOTE:
Outside the standard operating temperature (10 °C–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 40 °C–45°C, derate maximum allowable temperature by 1°C per 125 m
above 950 m (1°F per 228 ft).
