Replacing
hot-swap
fans
The
server
comes
with
four
hot-swap
fans:
two
front
fans
(fans
1
and
2),
and
two
center
fans
(fans
3
and
4).
You
do
not
have
to
turn
off
the
power
to
the
server
to
replace
a
hot-swap
fan.
If
the
server
is
equipped
with
the
IBM
xSeries
670-Watt
Hot-swap
Power-Supply
option,
two
rear
fans
(fans
5
and
6)
must
also
be
installed
on
the
server.
For
information
on
replacing
these
fans
or
installing
this
option,
see
“Replacing
a
rear
fan
(5
or
6)”
on
page
21
or
“Installing
the
670-Watt
hot-swap
power-supply
option”
on
page
23.
Attention:
To
help
ensure
proper
cooling,
if
a
fan
fails,
replace
it
within
48
hours.
