Table 1. Specifications (7X69 and 7X70) (continued)
Environment
ThinkSystem SR860 complies with ASHRAE class A2 specifications. Depending on the
hardware configuration, some solution models comply with ASHRAE Class A3 or Class
A4 specifications. System performance may be impacted when operating temperature
is outside ASHRAE A2 specification or fan failed condition.
Note: the GPU cards are not supported with ASHRAE Class A3 and Class A4
specifications.
The ThinkSystem SR860 is supported in the following environment:
• Air temperature:
– Operating
– ASHRAE Class A2: 10°C to 35°C (50°F to 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).
– ASHRAE 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).
– ASHRAE 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)
• Relative Humidity (non-condensing):
– Operating
– ASHRAE Class A2: 8% to 80%; maximum dew point: 21°C (70°F)
– ASHRAE Class A3: 8% to 85%; maximum dew point: 24°C (75°F)
– ASHRAE Class A4: 8% to 90%; maximum dew point: 24°C (75°F)
– Shipment/storage: 8% to 90%
• 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” in ThinkSystem SR860 Maintenance Manual.
