Electrical input
This server comes with three types of power supply units:
750-watt platinum power supply
input power 115V or 230V ac
1100-watt platinum power supply
input power 115V or 230V ac
1600-watt platinum power supply

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.
Particulate contamination Attention: Airborne particulates (including metal flakes or particles) and reactive gases acting alone or in combination with other environmental factors such as humidity or temperature might pose a risk to the device that is described in this document.
