Notes:
• 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, for example, with high-power NICs,
high-power processors and GPUs, such as ThinkSystem Mellanox ConnectX-6 HDR/200GbE QSFP56 1-port/2-
port PCIe Adapter, ThinkSystem Broadcom 57454 10GBASE-T 4-port OCP module.
• 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.
