Installing
a
microprocessor
This
section
describes
the
type
of
microprocessor
that
the
server
supports
and
other
information
that
you
must
consider
when
installing
a
microprocessor,
as
well
as
how
to
install
a
microprocessor
in
the
server.
Before
you
install
a
microprocessor,
read
the
following
information:
v
The
server
comes
with
one
microprocessor
installed.
The
following
illustration
shows
the
two
microprocessor
sockets
on
the
system
board.
The
voltage
regulator
modules
(VRMs)
for
microprocessors
1
and
2
are
integrated
on
the
system
board.
Microprocessor 2 (U2)
Microprocessor 2 error
LED (DLED14)
Microprocessor 1 (U1)
Microprocessor 1 error
LED (DLED13)
v
If
one
microprocessor
is
installed,
it
is
installed
in
microprocessor
socket
1
(U1)
and
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
(U2).
Notes:
1.
Read
the
documentation
that
comes
with
the
microprocessor
to
determine
if
you
need
to
update
the
BIOS
code.
The
most
current
level
of
BIOS
code
for
the
server
is
available
at
http://www.ibm.com/pc/support/.
For
additional
information,
see
the
User’s
Guide
on
the
IBM
Eserver
Documentation
CD.
2.
To
use
SMP,
obtain
an
SMP-capable
operating
system.
For
a
list
of
supported
operating
systems,
go
