Installing an additional microprocessor The following notes describe the type of microprocessor that your server supports and other information that you must consider when you install a microprocessor: v For a list of microprocessors that the server supports, see the ServerProven list at http://www.ibm.com/servers/eserver/serverproven/compat/us/. v The server comes with one microprocessor. The server supports a maximum of two microprocessors. The following illustration shows the two microprocessor sockets on the system board. Microprocessor 2 socket (CPU2) Microprocessor 1 socket (CPU1) v If only one microprocessor is installed, make sure that it is installed in microprocessor socket 1 (system-board identifier CPU1). Microprocessor 1 supports both the startup and application processes. v If you install a second microprocessor in the server, the server operates as a symmetric multiprocessing (SMP) server, and operating-system application programs can distribute the processing load between the microprocessors. This enhances performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications. Microprocessor 2 is installed in socket 2 (system-board identifier CPU2). v Read the documentation that comes with the microprocessor to determine whether you must update the BIOS code in the server. To download the most current level of BIOS code for your server, go to http://www.ibm.com/servers/ eserver/support/xseries/index.html and follow the instructions. Chapter 2.

Installing
an
additional
microprocessor
The
following
notes
describe
the
type
of
microprocessor
that
your
server
supports
and
other
information
that
you
must
consider
when
you
install
a
microprocessor:
v
For
a
list
of
microprocessors
that
the
server
supports,
see
the
ServerProven
list
at
v
The
server
comes
with
one
microprocessor.
The
server
supports
a
maximum
of
two
microprocessors.
The
following
illustration
shows
the
two
microprocessor
sockets
on
the
system
board.
Microprocessor 2
socket (CPU2)
Microprocessor 1
socket (CPU1)
v
If
only
one
microprocessor
is
installed,
make
sure
that
it
is
installed
in
microprocessor
socket
1
(system-board
identifier
CPU1).
Microprocessor
1
supports
both
the
startup
and
application
processes.
v
If
you
install
a
second
microprocessor
in
the
server,
the
server
operates
as
a
symmetric
multiprocessing
(SMP)
server,
and
operating-system
application
programs
can
distribute
the
processing
load
between
the
microprocessors.
This
enhances
performance
for
database
and
point-of-sale
applications,
integrated
manufacturing
solutions,
and
other
applications.
Microprocessor
2
is
installed
in
socket
2
(system-board
identifier
CPU2).
v
Read
the
documentation
that
comes
with
the
microprocessor
to
determine
whether
you
must
update
the
BIOS
code
in
the
server.
To
download
the
most
current
level
of
BIOS
code
for
your
server,
go
to
eserver/support/xseries/index.html
and
follow
the
instructions.
