Installing an additional microprocessor The blade server comes with at least one microprocessor. If the blade server comes with one microprocessor, you can install an additional microprocessor in the second microprocessor socket. If an MPE is installed, the blade server must have two microprocessors installed before the microprocessors on the MPE will become active. Additional microprocessors can be installed in the MPE. The blade server operates as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between the microprocessors. Note: If you install an additional microprocessor, you must install the same microprocessor type, speed, and power specifications as the first microprocessor. To use SMP, obtain an SMP-capable operating system. For a list of supported operating systems and other options, go to http://www.ibm.com/servers/eserver/ serverproven/compat/us/. The following notes describe the type of microprocessor that the server supports and other information that you must consider when installing a microprocessor: v Always install microprocessors that have the same cache size and type, the same clock speed, electrical specifications, and identical internal and external clock frequencies (including system bus speed). v Make sure that the microprocessor with the lowest feature set is the startup (bootstrap) microprocessor, which is installed in the microprocessor 1 socket (J244). v For a list of microprocessors that the blade server supports, go to the ServerProven list at http://www.ibm.com/servers/eserver/serverproven/compat/us/. v Before installing a new microprocessor, download and install the most current level of BIOS code, from http://www.ibm.com/bladecenter/. v The microprocessors terminate themselves; therefore, no terminator card is required if microprocessor socket 2 is empty on the blade server or on the MPE. However, for proper airflow, this socket must contain a microprocessor heat-sink filler, sometimes called a microprocessor baffle. v The microprocessor speeds are automatically set for this server; therefore, you do not have to set any microprocessor frequency-selection jumpers or switches. The following illustration shows how to install the second microprocessor on the system board for the blade server and also applies to the MPE. Chapter 3. Installing options 27

Installing
an
additional
microprocessor
The
blade
server
comes
with
at
least
one
microprocessor.
If
the
blade
server
comes
with
one
microprocessor,
you
can
install
an
additional
microprocessor
in
the
second
microprocessor
socket.
If
an
MPE
is
installed,
the
blade
server
must
have
two
microprocessors
installed
before
the
microprocessors
on
the
MPE
will
become
active.
Additional
microprocessors
can
be
installed
in
the
MPE.
The
blade
server
operates
as
a
symmetric
multiprocessing
(SMP)
server.
With
SMP,
certain
operating
systems
and
application
programs
can
distribute
the
processing
load
between
the
microprocessors.
Note:
If
you
install
an
additional
microprocessor,
you
must
install
the
same
microprocessor
type,
speed,
and
power
specifications
as
the
first
microprocessor.
To
use
SMP,
obtain
an
SMP-capable
operating
system.
For
a
list
of
supported
operating
systems
and
other
options,
go
to
serverproven/compat/us/.
The
following
notes
describe
the
type
of
microprocessor
that
the
server
supports
and
other
information
that
you
must
consider
when
installing
a
microprocessor:
v
Always
install
microprocessors
that
have
the
same
cache
size
and
type,
the
same
clock
speed,
electrical
specifications,
and
identical
internal
and
external
clock
frequencies
(including
system
bus
speed).
v
Make
sure
that
the
microprocessor
with
the
lowest
feature
set
is
the
startup
(bootstrap)
microprocessor,
which
is
installed
in
the
microprocessor
1
socket
(J244).
v
For
a
list
of
microprocessors
that
the
blade
server
supports,
go

ServerProven
list
at

Before
installing
a
new
microprocessor,
download
and
install
the
most
current
level
of
BIOS
code,
from
v
The
microprocessors
terminate
themselves;
therefore,
no
terminator
card
is
required
if
microprocessor
socket
2
is
empty
on
the
blade
server
or
on
the
MPE.
However,
for
proper
airflow,
this
socket
must
contain
a
microprocessor
heat-sink
filler,
sometimes
called
a
microprocessor
baffle.
v
The
microprocessor
speeds
are
automatically
set
for
this
server;
therefore,
you
do
not
have
to
set
any
microprocessor
frequency-selection
jumpers
or
switches.
The
following
illustration
shows
how
to
install
the
second
microprocessor
on
the
system
board
for
the
blade
server
and
also
applies
to
the
MPE.
