Chapter 4. Customer replaceable units This chapter provides instructions for adding options to your server. Some option-removal instructions are provided in case you need to remove one option to install another. Installation guidelines Before you begin to install options in your server, read the following information: v Become familiar with the safety and handling guidelines specified under "Handling static-sensitive devices" on page 46 and read the safety statements in "Safety information" on page 169. v You do not need to turn off the server to install or replace hot-swap power supplies, hot-swap drives, hot-swap fans, Active PCI (hot-plug) adapters, or hot-plug Universal Serial Bus (USB) devices. v The orange color on components and labels in your server identifies hot-swap or hot-plug component. You can install or remove hot-swap and hot-plug components while the system is running, provided that your system is configured to support this function. For complete details about installing or removing a hot-swap or hot-plug component, see the detailed information in this chapter. v The blue color on components and labels identifies touch points where you can grip a component, move a latch, and so on. v Make sure that you have an adequate number of properly grounded electrical outlets for your server, monitor, and any other options that you intend to install. v Back up all important data before you make changes to disk drives. v For a list of supported options for your server, go to http://www.ibm.com/pc/us/compat/ on the World Wide Web. System reliability considerations To help ensure proper cooling and system reliability, make sure that: v Each of the drive bays has either a drive or a filler panel installed. v Each of the power-supply bays has a power supply installed. v For tower models, make sure that there is at least 50 mm (2 inches) of ventilated space at the sides of the server and 100 mm (4 inches) at the front and rear of the server. For rack configurations, make sure that space is available around the server to enable the server cooling system to work properly. See the documentation that comes with the rack for additional information. v The server cover is in place during normal operation. v The air-baffle cover over the microprocessors remains closed during normal operation. v A removed hot-swap drive is replaced within 2 minutes of removal. v Cables for optional adapters are routed according to the instructions provided with the adapters. v A failed fan is replaced within 48 hours. v The server is turned off and the power cords are disconnected before you open the air-baffle cover. v The air-baffle assembly is always installed in the server except when you are installing or removing the components that are located under the air-baffle cover. © Copyright IBM Corp. 2002 45

to
install
another.
Installation
guidelines
Before
you
begin
to
install
options

your
server,
read
the
following
information:
v
Become
familiar
with
the
safety
and
handling
guidelines
specified
under
“Handling
static-sensitive
devices”
on
page
46
and
read
the
safety
statements
in
“Safety
information”
on
page
169.
v
You
do
not
need
to
turn
off
the

to
install
or
replace
hot-swap
power
supplies,
hot-swap
drives,
hot-swap
fans,
Active
PCI
(hot-plug)
adapters,
or
hot-plug
Universal
Serial
Bus
(USB)
devices.
v
The
orange
color
on
components
and
labels
in
your
server
identifies
hot-swap
or
hot-plug
component.
You
can
install
or
remove
hot-swap
and
hot-plug
components
while
the
system
is
running,
provided
that
your
system
is
configured
to
support
this
function.
For

System
reliability
considerations
To
help
ensure
proper
cooling
and
system
reliability,
make
sure
that:
v
Each
of
the
drive
bays
has
either
a
drive
or
a
filler
panel
installed.
v
Each
of
the
power-supply
bays
has
a
power
supply
installed.
v
For
tower
models,
make
sure
that
there
is
at
least
50
mm
(2
inches)
of
ventilated
space
at
the
sides
of
the
server
and
100
mm
(4
inches)
at
the
front
and
rear
of
the
server.
For
rack
configurations,
make
sure
that
space
is
available
around
the
server
to
enable
the
server
cooling
system
to
work
properly.
See
the
documentation
that
comes
with
the
rack
for
additional
information.
v
The
server
cover
is
in
place
during
normal
operation.
v
The
air-baffle
cover
over
the
microprocessors
remains
closed
during
normal
operation.
v
A
removed
hot-swap
drive
is
replaced
within
2
minutes
of
removal.
v
Cables
for
optional
adapters
are
routed
according
to
the
instructions
provided
with
the
adapters.
v
A
failed
fan
is
replaced
within
48
hours.
v
The
server
is
turned
off
and
the
power
cords
are
disconnected
before
you
open
the
air-baffle
cover.
v
The
air-baffle
assembly
is
always
installed
in
the
server
except
when
you
are
installing
or
removing
the
components
that
are
located
under
the
air-baffle
cover.
