Notes:
1. Government regulations (such as those prescribed by Occupational Safety and Health Administration or European Community
Directives) might govern noise level exposure in the workplace and might apply to you and your server installation. The actual
sound pressure levels in your installation depend on a variety of factors, including the number of racks in the installation; the
size, materials, and configuration of the room where you designate the racks to be installed; the noise levels from other
equipment; the room ambient temperature; and employees' location in relation to the equipment. Compliance with such
government regulations also depends on a variety of additional factors, including the duration of employees' exposure and
whether employees wear hearing protection. It is recommended that you consult qualified experts in this field to determine
whether you are in compliance with the applicable regulations.
