Environment ThinkSystem SR860 V2 complies with ASHRAE Class A2 specifications. Depending on 
the hardware configuration, some models comply with ASHRAE Class A3 and Class A4 
specifications. System performance may be impacted when operating temperature is 
outside AHSARE A2 specification. 
•  Air temperature: 
–  Operating 
–  ASHARE 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).
–  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)
•  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 
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” in ThinkSystem SR860 V2 Maintenance Manual.
Note: The server is designed for standard data center environment and recommended 
to be placed in industrial data center.
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.
