Dell EMC VxRail E series - Expanded operating temperature; Expanded operating temperature restrictions

Expanded operating temperature
When the appliance is in continuous operation, the expanded operating temperature ranges from
5°C to 40°C at 5% to 85% RH with 29°C dew point. Outside the standard operating temperature
(10°C to 35°C), the appliance 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 temperature by
1°C per 175 m above 950 m (1°F per 319 ft). When the appliance is operating at < 1% of annual
operating hours, the expanded operating temperature is –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
appliance 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).
