      • ASHARE Class A3: 5°C to 40°C (41°F to 104°F); the maximum ambient temperature decreases by 1°C for every 175 m (574 ft) increase in altitude above 900 m (2,953 ft).
      • ASHARE Class A4: 5°C to 45°C (41°F to 113°F); the maximum ambient temperature decreases by 1°C for every 125 m (410 ft) increase in altitude above 900 m (2,953 ft).
    • Server off: 5°C to 45°C (41°F to 113°F)
    • Shipment/storage: -40°C to 60°C (-40°F to 140°F)
  • Maximum altitude: 3,050 m (10,000 ft)

    • Shipment/storage: 8% to 90%
  • Particulate contamination
    Attention
    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 server. For information about the limits for particulates and gases, see Particulate contamination.
Note
To maintain component reliability, system performance might vary at ambient temperature higher than 35°C while all the fans are functioning. With one fan failing, system performance might vary at ambient temperature higher than 27°C.
