enhances
performance
for
database
and
point-of-sale
applications,
integrated
manufacturing
solutions,
and
other
applications.
Microprocessor
2
is
installed
in
socket
2
(U2).
v
If
one
microprocessor
and
four
DIMMs
are
installed
in
the
server
and
you
add
a
second
microprocessor
without
adding
more
DIMMs,
move
the
pair
of
DIMMs
in
memory
slots
3
and
4
to
memory
slots
7
and
8.
v
Read
the
documentation
that
comes
with
the
microprocessor
to
determine
whether
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

Documentation
CD.

Attention:
To
avoid
damage
and
to
ensure
proper
server
operation,
review
the
following
information
before
you
install
a
microprocessor:
v
Make
sure
that
the
microprocessors
are
the
same
type,
have
the
same
cache
size,
and
have
the
same
clock
speed.
v
See
the
ServerProven
list
at
http://www.ibm.com/pc/us/compat/
for
a
list
of
microprocessors
that
are
supported
by
the
server.
Complete
the
following
steps
to
install
a
microprocessor:
1.
Read
the
safety
information
beginning
on
page
v,
and
“Installation
guidelines”
on
page
9.
2.
Turn
off
the
server
and
all
attached
peripheral
devices.
Disconnect
all
power
cords;
then,
disconnect
all
external
signal
cables
from
the
server.
3.
Remove
the
server
from
the
rack;
then,
remove
the
server
cover
(see
“Removing
the
cover
and
bezel”
on
page
11).
Determine
the
socket
where
the
microprocessor
is
to
be
installed.
Attention:
v
Avoid
touching
the
components
and
gold-edge
connectors
on
the
microprocessor.
Make
sure
that
the
microprocessor
is
completely
and
correctly
seated
in
the
socket.
Incomplete
insertion
might
cause
damage
to
the
system
board
or
to
the
microprocessor.
v
When
you
handle
static-sensitive
devices,
take
precautions
to
avoid
damage
from
static
electricity.
For
information
about
handling
these
devices,
see
“Handling
static-sensitive
devices”
on
page
9.
4.
If
you
are
installing
a
microprocessor
in
the
microprocessor
2
socket,
lift
the
microprocessor-locking
lever
to
the
open
position.
