Installing an additional microprocessor Your server comes with one microprocessor installed on the system board. Your server supports up to two microprocessors. With two microprocessors, your server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load among the microprocessors. Before you begin: v Thoroughly review the documentation that comes with the microprocessor to determine the required BIOS update. The latest level of BIOS code for your server is available from the World Wide Web. See the User's Guide on the IBM xSeries Documentation CD for the World Wide Web addresses. v (Optional) Obtain an SMP-capable operating system. For a list of supported operating systems and other options, go to http://www.ibm.com/us/compat/ on the World Wide Web. Attention: To ensure proper server operation when you install an additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical. You can use the Configuration/Setup Utility program in your server to determine the specific type of microprocessor on your system board. Important: A microprocessor must always be installed in socket CPU1 of the system board. Notes: 1. To order additional microprocessor options, contact your IBM marketing representative or authorized reseller. 2. Terminator cards are not required for empty microprocessor sockets. However, for airflow, an empty microprocessor socket must contain a microprocessor baffle. 3. The microprocessor speeds are automatically set for this server; therefore, you do not need to set any microprocessor frequency-selection jumpers or switches. 4. If you need to replace a microprocessor, call for service. 5. For additional illustrations of the system-board components, see "System-board option connectors" on page 91. Configuring the operating system Some operating systems need to be configured to support an additional microprocessor. See your operating-system documentation for information. If Windows® 2000 is installed in the server, complete the following steps to configure the operating system. Check the Microsoft® web page at http://www.microsoft.com for updates to these instructions. In the Microsoft Web page, type multiprocessor support in the Search field and press Enter. 1. Back up the hard disk. 2. From the desktop, click Start → Settings → Control Panel. 3. In the Control Panel window, double-click the System icon. 4. In the System Properties window, click the Hardware tab; then, click Device Manager. 5. In the Device Manager window, click on the plus sign (+) beside Computer to expand the list; then, double-click ACPI Uniprocessor PC. Chapter 4. Installing options 57

Installing
an
additional
microprocessor
Your
server
comes
with
one
microprocessor
installed
on
the
system
board.
Your
server
supports
up
to
two
microprocessors.
With
two
microprocessors,
your
server
can
operate
as
a
symmetric
multiprocessing
(SMP)
server.
With
SMP,
certain
operating
systems
and
application
programs
can
distribute
the
processing
load
among
the
microprocessors.
Before
you
begin:
v
Thoroughly
review
the
documentation
that
comes
with
the
microprocessor
to
determine
the
required
BIOS
update.
The
latest
level
of
BIOS
code
for
your
server
is
available
from
the
World
Wide
Web.
See
the
User’s
Guide
on
the
IBM
xSeries
Documentation
CD
for
the
World
Wide
Web
addresses.
v
(Optional)
Obtain
an
SMP-capable
operating
system.
For
a
list
of
supported
operating
systems
and
other
options,
go
to
on
the
World
Wide
Web.
Attention:
To
ensure
proper
server
operation
when
you
install
an
additional
microprocessor,
use
microprocessors
that
have
the
same
cache
size
and
type,
and
the
same
clock
speed.
Microprocessor
internal
and
external
clock
frequencies
must
be
identical.
You
can
use
the
Configuration/Setup
Utility
program
in
your
server
to
determine
the
specific
type
of
microprocessor
on
your
system
board.
Important:
A
microprocessor
must
always
be
installed
in
socket
CPU1
of
the
system
board.
Notes:
1.
To
order
additional
microprocessor
options,
contact
your
IBM
marketing
representative
or
authorized
reseller.
2.
Terminator
cards
are
not
required
for
empty
microprocessor
sockets.
However,
for
airflow,
an
empty
microprocessor
socket
must
contain
a
microprocessor
baffle.
3.
The
microprocessor
speeds
are
automatically
set
for
this
server;
therefore,
you
do
not
need
to
set
any
microprocessor
frequency-selection
jumpers
or
switches.
4.
If
you
need
to
replace
a
microprocessor,
call
for
service.
5.

the
system-board
components,

Configuring
the
operating
system
Some
operating
systems
need
to
be
