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
7040
Model
W42
rack
is
available
with
an
optional
acoustical
door
feature
that
can
reduce
the
likelihood
of
exceeding
noise-level
exposure
limits
for
racks
densely
populated
with
pSeries
655
processor
subassemblies.
The
actual
sound-pressure
levels
in
your
installation
will
depend
on
a
variety
of
factors,
including
the
number
of
racks
in
the
installation;
the
size,
materials,
and
configuration
of
the
room
where
the
racks
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.
