Environmental specifications

Summary of the environmental specifications of server. Depending on the model, some features might not be available, or some specifications might not apply.

Acoustical noise emissions
The server has the following acoustic noise emissions declaration:
  • Sound power level (LWAd)
    • Idling:
      • 1U3N: 5.6 Bel
      • 1U2N: 4.5 Bel
    • Operating profile 1:
      • 1U3N: 5.6 Bel
      • 1U2N: 5.6 Bel
    • Operating profile 2:
      • 1U3N: 6.3 Bel
      • 1U2N: 6.3 Bel
  • Sound pressure level (LpAm):
    • Idling:
      • 1U3N: 39.7 dBA
      • 1U2N: 28.4 dBA
    • Operating profile 1:
      • 1U3N: 39.8 dBA
      • 1U2N: 39.4 dBA
    • Operating profile 2:
      • 1U3N: 46.1 dBA
      • 1U2N: 46.6 dBA
Note
  • These sound levels were measured in controlled acoustical environments according to procedures specified by ISO7779 and are reported in accordance with ISO 9296. Operating profile 1 is represented by 50% CPU TDP. Operating profile 2 is represented by 100% CPU TDP or 70%/30% storage write/read or 100% GPU. Testing was conducted at 23°C ± 2°C to align with ISO7779.
  • The declared acoustic sound levels are based on the specified configurations, which may change depending on configuration/conditions.
    • 1U3N configuration (3 nodes installed in enclosure with same configuration as following) :
      • Intel Ultra7 processors, 2x 32GB DDR5 CSODIMMs, 1x 480GB NVMe M.2 boot drive, 2X 1.92TB NVMe M.2 storage drive.
    • 1U2N configuration (1 node installed in enclosure with configuration as following) :
      • Intel Ultra7 processors, 2x 32GB DDR5 CSODIMMs, 1x 480GB NVMe M.2 boot drives, 1x 960GB NVMe storage M.2 drives, 1x Nvida RTX2000E ada GPU.
  • 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
ThinkEdge SE100 1U2N and 1U3N Enclosure (Type 7DGV) supports most of the configurations operating at temperature of 35°C or lower. Adjust ambient temperature when specific components are installed:

  • The following components can operate at temperature of 35°C or lower and require proper ambient temperature and redundant cooling by the fans to prevent performance degradation:

    • When one of the following components is installed, keep ambient temperature lower than 30°C for proper operation. When the ambient temperature is over 30°C, performance degradation might occur.
      • NVMe M.2 boot drives
  • The following components can operate at temperature of 35°C or lower and require proper system cooling with N+1 fan redundancy.
    • GPU adapter
Environment
ThinkEdge SE100 1U2N and 1U3N Enclosure complies with ASHRAE Class A2 specifications. System performance may be impacted when operating temperature is outside AHSARE A2 specification or fan failed condition. ThinkEdge SE100 1U2N and 1U3N Enclosure are supported in the following environment:
  • 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 35°C (41°F to 95°F)
  • Maximum altitude: 3,050 m (10,000 ft)
  • Relative Humidity (non-condensing):
    • Operating: Operating: 8% to 90%, maximum dew point: 24°C (75.2°F)
    • Shipment/storage: 8% to 90%, maximum dew point: 27°C (80.6°F)
    • Non-operating (unpacked) storage can pass the following condition: 5% to 95% at 38.7°C (101.7°F) maximum dry-bulb temperature for 48 hrs.
  • 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.
  • Shock and vibration specifications
    The following information is a summary of the shock and vibration specifications of the server. Depending on the model, some features might not be available, or some specifications might not apply.
  • 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.
