Notes:
1. Declared level L
Wad
is the upper-limit A-weighted sound power level. Declared level L
pAm
is the mean
A-weighted emission sound pressure level that is measured at the 1-meter bystander positions.
2. All measurements made in conformance with ISO 7779 and declared in conformance with ISO 9296.
3. 10 dB (decibel) equals 1 B (bel).
4. Notice: 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 IBM
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 various 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
various extra 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.
