• 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.
