Installing
and
replacing
a
microprocessor
The
following
notes
describe
the
types
of
microprocessors
that
your
server
supports
and
other
information
that
you
must
consider
when
installing
a
microprocessor:
v
Read
the
documentation
that
comes
with
the
microprocessor
to
determine
whether
you
need
to
update
the
basic
input/output
system
(BIOS)
code
in
your
server.
To
download
the
most
current
level
of
BIOS
code
for
the
server,
go
to
http://www.ibm.com/pc/support/.
v
If
your
server
comes
with
Intel
Xeon
MP
microprocessors,
obtain
an
SMP-capable
operating
system.
For
a
list
of
supported
operating
systems,
go
to
http://www.ibm.com/pc/compat/.
v
To
order
additional
microprocessor
or
SMP
Expansion
Module
options,
contact
your
IBM
marketing
representative
or
authorized
reseller.
v
To
avoid
damage
and
ensure
proper
server
operation
after
you
install
a
replacement
or
an
additional
microprocessor,
use
a
microprocessor
that
has
the
same
cache
size,
cache
type,
clock
speed,
and
internal
and
external
clock
frequencies
as
the
microprocessors
already
installed
in
the
individual
SMP
Expansion
Module.
For
a
list
of
microprocessors
supported
by
your
server,
see
the
ServerProven
list
at
on
the
World
Wide
Web.
v
The
microprocessor
in
socket
1
of
the
bottom
SMP
Expansion
Module
is
the
startup
(boot)
microprocessor.
v
An
air
baffle
or
microprocessor
must
be
installed
in
microprocessor
socket
4,
depending
on
your
configuration.
v
If
you
are
adding
Intel
Xeon
MP
microprocessors,
populate
the
empty
microprocessor
sockets
in
numeric
order,
starting
with
socket
1.
If
you
install
the
microprocessors
in
the
wrong
order,
the
server
will
not
start.
Attention:
You
must
ensure
that
the
locking
lever
on
the
microprocessor
socket
is
in
the
fully
open
position
before
you
insert
the
microprocessor
in
the
socket.
Failure
to
do
so
might
result
in
permanent
damage
to
the
microprocessor,
microprocessor
socket,
and
SMP
expansion
board.
See
v
Always
install
the
heat
sink
that
comes
with
the
microprocessor.
v
Server
models
that
come
with
Intel
Xeon
DP
microprocessors
support
a
maximum
of
two
microprocessors
per
SMP
Expansion
Module,
installed
in
microprocessor
sockets
1
and
4.
v
Intel
Xeon
MP
microprocessors
are
supported
in
microprocessor
sockets
1,
2,
3,
and
4.
shows
the
location
of
the
startup
microprocessor
and
its
VRM
on
the
SMP
expansion
board.
It
also
shows
the
microprocessor
baffles
and
the
VRM
slots
for
the
other
microprocessor
sockets.
Note:
The
illustrations
in
this

might
differ
slightly
