EnvironmentThinkSystem SR665 V3 is designed for standard data center environment and is recommended to be placed inindustrial data center. Depending on hardware configurations, the server complies with ASHRAE Class H1, A2, A3, orA4 specifications with certain thermal restrictions. For detailed thermal information, see “Thermal rules” on page 47.System performance may be impacted when operating temperature is outside permitted conditions.• Air temperature:– Operating– ASHRAE class H1: 5°C to 25°C (41°F to 77°F)The maximum ambient temperature decreases by 1°C for every 500 m (1640 ft) increase in altitude above 900m (2,953 ft)– 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 900m (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 900m (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 900m (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 H1: 8%–80%; maximum dew point: 17°C (62.6°F)– ASHRAE class A2: 8%–80%; maximum dew point: 21°C (70°F)– ASHRAE class A3: 8%–85%; maximum dew point: 24°C (75°F)– ASHRAE class A4: 8%–90%; maximum dew point: 24°C (75°F)– Shipment/storage: 8% to 90%Particulate contaminationAttention: Airborne particulates (including metal flakes or particles) and reactive gases acting alone or incombination with other environmental factors such as humidity or temperature might pose a risk to thedevice that is described in this document.Risks that are posed by the presence of excessive particulate levels or concentrations of harmful gasesinclude damage that might cause the device to malfunction or cease functioning altogether. Thisspecification sets forth limits for particulates and gases that are intended to avoid such damage. The limitsmust not be viewed or used as definitive limits, because numerous other factors, such as temperature ormoisture content of the air, can influence the impact of particulates or environmental corrosives and gaseouscontaminant transfer. In the absence of specific limits that are set forth in this document, you mustimplement practices that maintain particulate and gas levels that are consistent with the protection of humanhealth and safety. If Lenovo determines that the levels of particulates or gases in your environment havecaused damage to the device, Lenovo may condition provision of repair or replacement of devices or partson implementation of appropriate remedial measures to mitigate such environmental contamination.Implementation of such remedial measures is a customer responsibility.Chapter 1.
