Note

  • These sound power levels are measured in controlled acoustical environments according to procedures specified by ISO 7779 and are reported in accordance with ISO 9296.

  • The declared sound levels may change depending on configuration/conditions.

  • 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.

Ambient temperature management​

Ambient temperature management
The server is supported in the following environment:

  • Air temperature:

    • Operating:

      • ASHRAE class H1: 5–25°C (41–77°F); when the altitude exceeds 900 m (2953 ft), the maximum ambient temperature value decreases by 1°C (1.8°F) with every 500 m (1640 ft) of altitude increase.

      • 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.

      • ASHRAE class A3: 5–40°C (41–104°F); when the altitude exceeds 900 m (2953 ft), the maximum ambient temperature value decreases by 1°C (1.8°F) with every 175 m (574 ft) of altitude increase.

      • ASHRAE class A4: 5–45°C (41–113°F); when the altitude exceeds 900 m (2953 ft), the maximum ambient temperature value decreases by 1°C (1.8°F) with every 125 m (410 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 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 or storage: 8%–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.

Environment​

Environment
HS350X V3 complies with ASHRAE Class A2 specifications. System performance may be affected when operating temperature is outside of 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.
Note

The server is designed for standard data center environment and recommended to be placed in industrial data centers.

When the ambient temperature is greater than the supported max temperature (ASHARE A4 45°C), the server will shut down. The server will not power on again until the ambient temperature falls within the supported temperature range.

Depending on hardware configurations, the server complies with ASHRAE Class H1, A2, A3, or A4 specifications with certain thermal restrictions. System performance may be impacted when operating temperature is out of permitted conditions.

  • 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.
