Expanded operating temperature Specications
NOTE: Outside the standard operating temperature (10°C to
40°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 may be reported on the bezel's LCD
panel and in the System Event Log.
