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. The BladeCenter modules The BladeCenter unit contains the following hot-swap modules: v Advanced management modules v I/O modules v Power modules v Blower modules Chapter 1. Introduction 3
