environments
according
to
ISO

and
are
reported
in
accordance
with
ISO

The
declared
sound

levels
indicate
an
upper
limit,
below
which
a
large
portion
of
machines
operate.
Sound
pressure
levels
in
your
location
might
exceed
the
average
1-meter

stated
because
of
room
reflections
and
other
nearby
noise.
Storage
server
components
The
following
sections
show
the
components
of
the
storage
server.
The
hot-swap
features
of
the
storage
server
enable
you
to
remove
and
replace
hard
disk
drives,
power
supplies,
RAID
controllers,
and
fans
without
turning
off
the
storage
server.
Therefore,
you
can
maintain
the
availability
of
your
system
while
a
hot-swap
device
is
removed,
installed,
or
replaced.
