Expanded operating temperature Specifications
5°C-45°C for a maximum of 1% of its annual operating
hours.
For temperatures between 40°C-45°C, derate 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 in the System
Event Log.
