Both
fan
units
must
always
be
in
place,
even
if
one
is
not
functioning
properly,
to
maintain
proper
cooling.
Use
the
following
procedure
to
replace
a
hot-swap
fan:
1.
Check
the
LEDs
on
the
back
of
the

Working
with
power
supplies
The
power
supply
CRUs
provide
power
to
the
internal
components
by
converting
incoming
ac
voltage
to
dc
voltage.
The
DS4100
base
storage
server
power
system
operates
with
two
power
supply
CRUs
that
can
be
hot-swapped.
In
the
DS4100
base
storage
server,
one
power
supply
CRU
can
maintain
electrical
power
to
the
unit
if
the
other
power
supply
is
turned
off
or
malfunctions.
The
power
supply
CRUs
are
interchangeable
(by
reversing
the
locking
levers).
The
DS4100
single-controller
storage
server
has
only
one
power
supply
CRU.
You
cannot
remove
or
replace
a
working
(non-failed)
power
supply
in
the
DS4100
single-controller
storage
server
without
first
powering
down
the
storage
subsystem.
Before
you
replace
the
power
supply
in
the
DS4100
single-controller
storage
server,
all
I/O
activity
must
be
stopped
and
the
storage
server
must
be
powered
down.
