temperature
Specifications
For temperatures between 40°C and 45°C, derate maximum allowable temperature by 1°C per 125 m
(1°F per 228 ft) above 950 m (3.117 ft).
NOTE:
When operating in the expanded temperature range, the performance of the system may be impacted.
NOTE:
When operating in the expanded temperature range, ambient temperature warnings may be reported on the LCD
panel and in the System Event Log.
Expanded operating range
•
The operating temperature is specified for a maximum altitude of 950 m for expanded operating range.
•
Do not perform cold start at 5°C or lower, due to hard drive constraints.
•
Redundant power supplies are required.
