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.

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.
