Specification
Description
installation depend upon a variety of factors, including the number of racks in the 
installation; the size, materials, and configuration of the room; the noise levels 
from other equipment; the room ambient temperature, and employee's location in 
relation to the equipment. Further, compliance with such government regulations 
depends on a variety of additional factors, including the duration of employees' 
exposure and whether employees wear hearing protection. Lenovo recommends 
that you consult with qualified experts in this field to determine whether you are in 
compliance with the applicable regulations.
Environment
ThinkSystem SR670 V2 complies with ASHRAE Class A2 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).
–  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)
–  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” on page 8.
Note: The server is designed for standard data center environment and 
recommended to be placed in industrial data center.
