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. Under certain environments, configurations, system settings, and workloads, fan speeds are increased that
result in higher noise levels.
5. 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.
