Standard operating temperature

Table 13. Standard operating temperature specifications

Standard operating temperature Specifications

Continuous operation (for altitude less than 950 m or 3117

ft)

+5°C–45°C (41°F–113°F) with no direct sunlight on the equipment

NOTE: The 150W CPU support is only up to 35°C.

NOTE: GPU continuous operation is supported up to 30°C.

NOTE: GPU continuous operation is supported up to 45°C with

optional fan booster kit.

Expanded operating temperature

Table 14. Expanded operating temperature specifications

Expanded operating temperature Specifications

Continuous operation 5°C to 45°C at 5% to 85% RH with 29°C dew point.

NOTE: Outside the standard operating temperature (10°C to

35°C), the system can operate continuously in temperatures as

low as 5°C and as high as 45°C.

For temperatures between 35°C and 45°C, de-rate maximum allowable

temperature by 1°C per 175 m above 950 m (1°F per 319 ft).

≤ 1% of annual operating hours –5°C to 55°C at 5% to 90% RH with 29°C dew point.

NOTE: Outside the standard operating temperature (10°C to

35°C), the system can operate down to –5°C or up to 55°C for a

maximum of 1% of its annual operating hours.

NOTE: GPU expanded operating temperatures is up to 37°C for

selected configurations.

NOTE: GPU expanded operating temperatures is up to 50°C for

selected configurations with optional fan booster kit.

For temperatures between 45°C and 55°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 LCD

panel and in the System Event Log.

Expanded operating temperature restrictions

• Do not perform cold start below -15C Per IEC 60945.

• The operating temperature specified is for a maximum altitude of 950 m.

• Redundant power supplies are required.
