Installing
a
hot-swap
power
supply
The
following
notes
describe
the
type
of
power
supply
that
the
server
supports
and
other
information
that
you
must
consider
when
installing
a
power
supply:
v
The
server
comes
with
one
670-watt
hot-swap
12-volt
output
power
supply.
The
input
voltage
is
110
V
ac
or
220
V
ac
auto-sensing.
v
You
can
install
an
optional
670-watt
hot-swap
12-volt
output
power
supply
to
use
as
a
redundant
power
supply.
v
These
power
supplies
are
designed
for
parallel
operation.
In
the
event
of
a
power-supply
failure,
the
redundant
power
supply
continues
to
power
the
system.
The
server
supports
a
maximum
of
two
power
supplies.
Note:
If
you
are
using
a
Y
power
cable
between
two
servers
that
act
as
backup
power
units,
see
“Installing
a
Y
power
cable”
on
page

for
information
about
how
to
connect
a
Y
power
cable.
