Notes:
1. Declared level L
WAd
is the upper-limit A-weighted sound power level. Declared level L
pAm
is the mean A-
weighted sound pressure level that is measured at the 1-meter bystander positions.
2. All measurements are made in conformance with ISO 7779 and declared in conformance with ISO 9296.
3. "B" and "dB" are abbreviations for bels and decibels. 1 B = 10 dB.
Important: Government regulations (such as those prescribed by OSHA or European Community Directives)
might govern noise level exposure in the workplace and might apply to you and your server installation. This
system is available with an optional acoustical door feature that can help reduce the noise that is emitted from
this system. 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 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. Further, compliance with such government regulations also
depends upon a variety of additional factors, including the duration of employees' exposure and whether
employees wear hearing protection. IBM recommends that you consult with qualified experts in this field to
determine whether you are in compliance with the applicable regulations.
