Environment:
Server on
• Maximum altitude: 3,050 m (10,000 ft), 5°C to 28°C (41°F to 82°F)
Attention:
– Design to ASHRAE Class A3, Temperature: 36°C - 40°C (96.8°F - 104°F) with relaxed support:
– Support cloud like workload with no performance degradation acceptable (Turbo-Off).
– Under no circumstance, can any combination of worst case workload and configuration result
in system shutdown or design exposure at 40°C.
– The worst case workload (such as Linpack, Turbo-On) may have performance degradation.
• Temperature:
– 5°C to 40°C (41°F to 104°F)
– Altitude: 0 to 950 m (3,117 ft); decrease the maximum system temperature by 1°C for every
175-m increase in altitude.
• Humidity:
– Non-condensing: -12°C dew point (10.4°F)
– Relative humidity: 8% to 85%
• Maximum dew point: 24°C (75°F)
• Maximum rate of temperature change:
– Hard disk drives: 20°C/hr (68°F/hr)
Environment:
Server off :
• Temperature: 5°C to 45°C (41°F to 113°F)
• Relative humidity: 8% to 85%
• Maximum dew point: 27°C (80.6°F)
Storage (non-operating):
• Temperature: 1°C to 60°C (33.8°F to 140.0°F)
• Maximum altitude: 3,050 m (10,000 ft)
• Relative humidity: 5% to 80%
• Maximum dew point: 29°C (84.2°F)
Shipment (non-operating):
• Temperature: -40°C to 60°C (-40°F to 140.0°F)
• Maximum altitude: 10,700 m (35,105 ft)
• Relative humidity: 5% to 100%
• Maximum dew point: 29°C (84.2°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 server. For
information about the limits for particulates and gases, see “Particulate contamination” on page 1141.
