Removing and replacing a blower module
Your BladeCenter might be equipped with standard blower modules (part number
44E5083), or it might be equipped with high-efficiency blower modules (part
number 68Y8205). The standard and high-efficiency blower modules are not
interchangeable and should not be mixed in the same BladeCenter unit.
Attention: Failed blower modules should only be replaced with the same type of
blower module.
Note: 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.
