Replacing and troubleshooting fans Your xSeries 445 server has four hot-swap fan assemblies, two 150 mm x 38 mm, and two 150 mm x 51 mm fans. The two 150 mm x 38 mm fans (fan 3 and fan 4) are located in front of the PCI-X planar and are used to cool the power supplies, PCI-X slots, and the I/O board. The two 150 mm x 51 mm fans (fan 1 and fan 2) are located toward the front of the server and are used to cool the SMP Expansion Modules. See the following illustration. Note: The illustrations in this document might differ slightly from your hardware. Fan 4 Latch release Fan 3 Fan NOTE: FOR PROPER FRONT OF BOX AIRFLOW, REPLACE FAN WITHIN 2 MINUTES 2 NOTE: FOR PROPER FRONT OF BOX AIRFLOW, REPLACE FAN WITHIN 2 MINUTES Fan 1 Figure 71. Fans Each fan has an LED located on the top left side. When the fan is operating correctly, this LED is off. If a fan stops working, the Light Path Diagnostics feature will light a system-error light on the front of the server, indicating that there is a problem and guide you to the defective fan. When this occurs, first identify the defective fan; then, using the appropriate procedure, remove and replace the fan. Replacing fans 1 and 2 As shown in the following illustration, fans 1 and 2 are located on the right side of the server, and cool the SMP Expansion Modules. These fans are redundant, meaning that if one fails, the remaining fan will temporarily speed up to properly cool the SMP Expansion Modules. In the event of a failure, replace the malfunctioning fan within 48 hours. Complete the following steps to replace fans 1 and 2: 1. Read the safety information in "Installation guidelines" on page 79 and "Safety information" on page 257. Attention: All fans must be replaced within 48 hours of failing. 2. Pull out on the quick release latches on each side of the server; then, pull the server out of its rack enclosure until it stops. 122 xSeries 445 Type 8870: Hardware Maintenance Manual and Troubleshooting Guide

Replacing
and
troubleshooting
fans
Your
xSeries
445
server
has
four
hot-swap
fan
assemblies,
two
150
mm
x
38
mm,
and
two
150
mm
x
51
mm
fans.
The
two
150
mm
x
38
mm
fans
(fan
3
and
fan
4)
are
located
in
front
of
the
PCI-X
planar
and
are
used
to
cool
the
power
supplies,
PCI-X
slots,
and
the
I/O
board.
The
two
150
mm
x
51
mm
fans
(fan
1
and
fan
2)
are
located
toward
the
front
of
the
server
and
are
used
to
cool
the
SMP
Expansion
Modules.
See
the
following
illustration.
Note:
The
illustrations
in
this
document
might
differ
slightly
from
your
hardware.
Each
fan
has
an
LED
located
on
the
top
left
side.
When
the
fan
is
operating
correctly,
this
LED
is
off.
If
a
fan
stops
working,
the
Light
Path
Diagnostics
feature
will
light
a
system-error
light
on
the
front
of
the
server,
indicating
that
there
is
a
problem
and
guide
you
to
the
defective
fan.
When
this
occurs,
first
identify
the
defective
fan;
then,
using
the
appropriate
procedure,
remove
and
replace
the
fan.
Replacing
fans
1
and
2
As
shown
in
the
following
illustration,
fans
1
and
2
are
located
on
the
right
side
of
the
server,
and
cool
the
SMP
Expansion
Modules.
These
fans
are
redundant,
meaning
that
if
one
fails,
the
remaining
fan
will
temporarily
speed
up
to
properly
cool
the
SMP
Expansion
Modules.
In
the
event
of
a
failure,
replace
the
malfunctioning
fan
within
48
hours.
Complete
the
following
steps
to
replace
fans
1
and
2:
1.
Read
the
safety
information
in
“Installation
guidelines”
on
page
79
and
“Safety
information”
on
page
257.
Attention:
All
fans
must
be
replaced
within
48
hours
of
failing.
2.
Pull
out
on
the
quick
release
latches
on
each
side
of
the
server;
then,
pull
the
server
out
of
its
rack
enclosure
until
it
stops.
