L
WAd
is
the
upper-limit
A-weighted
sound
level;
LpAm
is
the
mean
A-weighted
sound
pressure
level
measured
at
the
1-meter
bystander
positions;
1
B
=
10

All
measurements
made
in

and

Attention:
Your
server
installation
may
be
subject
to
government
regulations
(such
as
those
prescribed
by
OSHA
or
European
Community
Directives)
that
cover
noise-level
exposure
in
the
workplace.
The
pSeries
655
is
available
with
an
optional
acoustical
door
feature
that
can
reduce
the
likelihood
of
exceeding
noise-level
exposure
limits.
The
actual
sound-pressure
levels
in
your
installation
will
depend
on
a
variety
of
factors,
including
the
number
of
servers
in
the
installation;
the
size,
materials,
and
configuration
of
the
room
where
the
server(s)
is(are)
installed;
the
noise
levels
from
other
equipment;
the
room
ambient
temperature,
and
employees’
location
in
relation
to
the
equipment.
It
is
recommended
that
a
qualified
person,
such
as
an
industrial
hygienist,
be
consulted
to
determine
whether
the
sound-pressure
levels
to
which
employees
may
be
exposed
exceed
regulatory
limits.

These
numbers
are
based
on
preliminary
data
and
are
subject
to
change.
