Note
  • These sound levels were measured in controlled acoustical environments according to procedures specified by ISO7779 and are reported in accordance with ISO 9296.
  • The declared acoustic sound levels are based on the following configurations, which may change depending on configuration/conditions:

    • Minimum configuration: 1x 125W CPU, 4x 16GB RDIMM, 4x 3.5” SAS HDD, SW RAID, 2x onboard 10GB LAN ports, 1x 750W PSU

    • Typical configuration: 2x 150W CPU, 4x 32GB RDIMM, 8x 3.5” SAS HDD, RAID 940-8i, 2x onboard 10GB LAN ports, 2x 750W PSU

    • GPU rich configuration: 2x 150W CPU, 32x 64GB RDIMM, 8x 3.5” SAS HDD, 1xRAID 940-8i, 2x onboard 10GB LAN ports, 8x NVDIA A2 GPU, 2x 1800W PSU

    • Storage rich configuration: 2x 195W CPU, 32x 64GB RDIMM, 32x 2.5” SAS HDD, 2x RAID 940-16i, 2x onboard 10GB LAN ports, 2x 1800W PSU

  • 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.
