  • These sound levels were measured in controlled acoustical environments according to procedures specified by ISO7779 and are reported in accordance with ISO 9296.

  • Government regulations (such as those prescribed by OSHA or European Community Directives) may govern noise level exposure in the workplace and may apply to you and your server installation. The actual sound pressure levels in your 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.

The server is supported in the following environment:
This server is designed for standard data center environment and recommended to be placed in industrial data center.
  • Air temperature:

    • Operating: ASHRAE class A2: 10–35°C (50–95°F); when the altitude exceeds 900 m (2953 ft), the maximum ambient temperature value decreases by 1°C (1.8°F) with every 300 m (984 ft) of altitude increase.

    • Server off: 5–45°C (41–113°F)

    • Shipping or storage: -40–60°C (-40–140°F)

  • Maximum altitude: 3050 m (10 000 ft)

  • Relative humidity (non-condensing):

    • Operating: ASHRAE class A2: 8%–80%; maximum dew point: 21°C (70°F)

    • Shipping or storage: 8%–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.

Your server complies with ASHRAE class A2 specifications.

Depending on the hardware configuration, some server models comply with ASHRAE class A3 and class A4 specifications, see ASHRAE class compliance information.
