Notes:
1. Declared level L
WA,m
is the upper-limit A-weighted sound power level. Declared level L
PA,m
is the
mean A-weighted emission sound pressure level that is measured at the 1-meter bystander
positions.
2. The statistical adder for verication, K
v
, is a quantity to be added to the declared mean A-weighted
sound power level, L
WA,m
, such that there is a 95% probability of acceptance, when using the
verication procedures of ISO 9296, if no more than 6.5% of the batch of new equipment has A-
weighted sound power levels greater than (L
WA,m
+ K
v
).
3. The quantity L
WA,c
(formerly called L
WAd
), can be computed from the sum of L
WA,m
and K
v
.
4. All measurements made in conformance with ISO 7779 and declared in conformance with ISO 9296.
5. 10 dB (decibel) equals 1 B (bel).
6. 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 in racks with optional acoustical door features 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 conguration 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 qualied experts in this eld to determine
whether you are in compliance with the applicable regulations.

Special Hardware Management Console considerations
When the server is managed by an HMC, the console must be provided within the same room and within 8
m (26 ft) of the server. For more considerations, see Installing and conguring the HMC.
Note: As an alternative to the local HMC requirement, you can provide a supported device, such as a PC,
with connectivity and authority to operate through a remotely attached HMC. This local device must be in
the same room and within 8 m (26 ft) of your server. This local device must provide functional capabilities
