review
the
following
information:
v
During
normal
nonredundant
operation,
a
power
supply
must
be
installed
in
the
power
supply
1
position
and
a
filler
panel
in
the
power
supply
2
position.
v
During
normal
redundant
operation,
a
second
hot-swap
power
supply
and
the
two
rear
hot-swap
fans
must
be
installed
in
the
server.
Attention:
To
help
ensure
proper
cooling,
if
a
fan
fails,
replace
it
within
48
hours.
v
When
the
670-Watt
hot-swap
power
supply
option
is
installed
in
the
server,
the
addition
of
the
two
fans
enables
the
redundant
cooling
feature.
If
any
of
the
fans
fail
the
other
fans
will
speed
up
when
needed
to
help
keep
the
server
cool
and
working
properly.
v
Two
cable-restraint
brackets
are
on
the

install
the
670-Watt
hot-swap
power-supply
option
and
connect
the
cables
to
the
selected
devices,
you
can
use
these
cable-restraint
brackets
to
manage
the
cable
routing.
Route
the
power
cords
through
the
power-cord
restraint
bracket.
Route
the
remaining
cables
(for
example,
the
cables
that
are
connected
to
the
I/O
connectors)
through
the
I/O
cable-restraint
bracket.
