Ambient temperature managementAdjust ambient temperature when specific components are installed:
  • Keep ambient temperature to 30°C or lower when one or more of the following processors are installed:
    • Processors with TDP (thermal design power) 165 watts or lower
  • Keep ambient temperature to 25°C or lower when one or more of the following processors are installed:
    • Processors with TDP (thermal design power) higher than 165 watts
    • Intel(R) Xeon(R) Gold 6334 (165 watts, 8 core)
EnvironmentThe ThinkSystem SD630 V2 Compute Node complies with ASHRAE Class A2 specifications.
The ThinkSystem SD630 V2 Compute Node is supported in the following environment:
  • Air temperature:

    • Operating: 10°C - 35°C (50°F - 95°F); the maximum ambient temperature decreases by 1°C for every 300 m (984 ft) increase in altitude above 900 m (2,953 ft)
    • Solution powered off: 5°C to 45°C (41°F to 113°F)
  • Maximum altitude: 3,050 m (10,000 ft)

  • Relative humidity (non-condensing):

    • Operating: 20% - 80%, maximum dew point: 21°C (70°F)
    • Solution powered off: 8% - 80%, maximum dew point: 27°C (81°F)
  • Particulate contamination:

    Airborne particulates and reactive gases acting alone or in combination with other environmental factors such as humidity or temperature might pose a risk to the solution. For information about the limits for particulates and gases, see Particulate contamination.
