following
illustration
shows
the
microprocessor
connectors
and
the
microprocessor
voltage
regulator
module
(VRM)
connectors
on
the
microprocessor
board.
Note:
The
voltage
regulators
for
microprocessors
1
and
2
are
integrated
on
the
microprocessor
board;
the
VRMs
for
microprocessors
3
and
4
come
with
the
microprocessor
options
and
must
be
installed
on
the
microprocessor
board.

v
If
one
microprocessor
is
installed:
–
The
microprocessor
is
installed
in
microprocessor
connector
1
(U22).
–
The
microprocessor
supports
both
the
startup
and
application
processes.
v
If
you
install
additional
microprocessors
in
the
server,
microprocessor
2
is
installed
in
microprocessor
connector
2
(U23);
microprocessor
3
is
installed
in
connector
3
(U24);
microprocessor
4
is
installed
in
connector
4
(U25).
v
A
new
microprocessor
comes
in
a
kit
with
a
VRM
and
a
heat
sink.
The
VRM
is
used
only
with
microprocessor
3
or
4.
v
Read
the
documentation
that
comes
with
the
microprocessor
to
determine
whether
you
need
to
update
the
server
basic
input/output
system
(BIOS)
code.
The
most
current
level
of
BIOS
code
for
the
server
is
available
from
http://www.ibm.com/pc/support.
v
To
use
SMP,
obtain
an
SMP-capable
operating
system.
