starts so that you can save the new configuration information. See the User's Guide on the IBM xSeries Documentation CD for more information about the Configuration/Setup Utility program. Some options have device drivers that you need to install. See the documentation that comes with your option for information about installing any required device drivers. Your server comes with one or two microprocessors installed on the system board. If your server comes with two microprocessors, or if your server comes with one microprocessor and you have installed an additional microprocessor, your server can now operate as an SMP server. Therefore, you might need to upgrade your operating system to support SMP. See the ServerGuide information in the User's Guide on the IBM xSeries Documentation CD and to your operating-system documentation for additional information. If your server has a RAID configuration using the integrated SCSI controller with RAID capabilities or has a ServeRAID controller installed and you have installed or removed a hard disk drive, see the ServeRAID documentation on the IBM ServeRAID Support CD for information about configuring your disk arrays. Connecting external options If you install an optional SCSI adapter, or use channel B on the integrated SCSI controller for external devices, you can attach external SCSI devices, such as a SCSI storage expansion enclosure, to your server. To use channel B for external SCSI devices, remove the SCSI knockout from the rear of the server and secure the free end of the channel B cable in the new opening. You can attach additional external options to the input/output (I/O) connectors on the front and rear of your server. (See "System-board option connectors" on page 91 for more information.) Complete the following steps to attach an external device: 1. Review the safety information beginning on page 129 "Installation guidelines" on page 33, and the documentation that comes with your options. 2. Turn off the server and all attached devices. 3. Follow the instructions that come with the option to prepare it for installation and to connect it to the server. Note: If you are attaching an external SCSI device, see "Ultra320 SCSI connector" on page 71 for information about SCSI cabling and SCSI IDs. Installing the server in a rack An optional Tower-to-Rack Kit is needed to convert your server from a tower model to a rack model. You can then install the server in a rack cabinet. To order a Tower-to-Rack Kit for your server, contact your IBM marketing representative or authorized reseller. 68 IBM xSeries 225 Types 8649: Hardware Maintenance Manual and Troubleshooting Guide

that
you
can
save
the
new
configuration
information.
See
the
User’s
Guide
on
the
IBM
xSeries
Documentation
CD
for
more
information
about
the
Configuration/Setup
Utility
program.
Some
options
have
device
drivers
that
you
need
to
install.
See
the
documentation
that
comes
with
your
option
for
information
about
installing
any
required
device
drivers.
Your
server
comes
with
one
or
two
microprocessors
installed
on
the
system
board.
If
your
server
comes
with
two
microprocessors,
or
if
your
server
comes
with
one
microprocessor
and
you
have
installed
an
additional
microprocessor,
your
server
can
now
operate
as
an
SMP
server.
Therefore,
you
might
need
to
upgrade
your
operating
system
to
support
SMP.
See
the
ServerGuide
information
in
the
User’s
Guide
on
the
IBM
xSeries
Documentation
CD
and
to
your
operating-system
documentation
for
additional
information.
If
your
server
has
a
RAID
configuration
using
the
integrated
SCSI
controller
with
RAID
capabilities
or
has
a
ServeRAID
controller
installed
and
you
have
installed
or
removed
a
hard
disk
drive,
see
the
ServeRAID
documentation
on
the
IBM
ServeRAID
Support
CD
for
information
about
configuring
your
disk
arrays.
Connecting
external
options
If
you
install
an
optional
SCSI
adapter,
or
use
channel
B
on
the
integrated
SCSI
controller
for
external
devices,
you
can
attach
external
SCSI
devices,
such
as
a
SCSI
storage
expansion
enclosure,
to
your
server.
To
use
channel
B
for
external
SCSI
devices,
remove
the
SCSI
knockout
from
the
rear
of
the
server
and
secure
the
free
end
of
the
channel
B
cable
in
the
new
opening.
You
can
attach
additional
external
options
to
the
input/output
(I/O)
connectors
on
the
front
and
rear
of
your
server.
(See
“System-board
option
connectors”
on
page
91
for
more
information.)
Complete
the
following
steps
to
attach
an
external
device:
1.
Review
the
safety
information
beginning
on
page
129
“Installation
guidelines”
on
page
33,
and
the
documentation
that
comes
with
your
options.
2.
Turn
off
the
server
and
all
attached
devices.
3.
Follow
the
instructions
that
come
with
the
option
to
prepare
it
for
installation
and
to
connect
it
to
the
server.
Note:
If
you
are
attaching
an
external
SCSI
device,
see
“Ultra320
SCSI
connector”
on
page
71
for
information
about
SCSI
cabling
and
SCSI
IDs.
Installing
the
server
in
a
rack
An
optional
Tower-to-Rack
Kit
is
needed
to
convert
your
server
from
a
tower
model
to
a
rack
model.
You
can
then
install
the
server
in
a
rack
cabinet.
To
order
a
Tower-to-Rack
Kit
for
your
server,
contact
your
IBM
marketing
representative
or
authorized
reseller.
