frequencies
must
be
identical.
You
can
use
the
Configuration/Setup
Utility
program
to
determine
the
specific
type
of
microprocessor
that
is
installed
on
the
system
board.
v
Read
the
documentation
that
comes
with
the
microprocessor
to
determine
whether
you
must
update
the
basic
input/output
system
(BIOS)
code
in
the
server.
To
download
the
most
current
level
of
BIOS
code
for
the
server,
seehttp://www.ibm.com/support/.

Obtain
an
SMP-capable
operating
system.

To
install
a
microprocessor,
complete
the
following
steps:
1.
Read
the
safety
information
that
begins
on
page
v
and
“Installation
guidelines”
on
page
21.
2.
Turn
off
the
server
and
peripheral
devices;
then,
disconnect
the
power
cords
and
all
external
cables.
Remove
the
cover.
Attention:
The
microprocessor
retention
latch
is
spring-loaded
when
the
microprocessor
is
in
place.
Releasing
the
latch
too
quickly
or
allowing
it
to
spring
upward
can
damage
the
microprocessor
and
surrounding
components.
3.
Remove
the
microprocessor
air
duct
from
the
fan
cage:
a.
Grasp
the
two
pinch
points
on
the
top
of
the
air
duct
and
squeeze
them
together.
b.
Lift
the
air
duct
up
and
out
of
the
server
and
set
it
aside.
4.
Release
the
microprocessor
retention
latch
by
pressing
down
on
the
end,
moving
it
to
the
side,
and
slowly
releasing
it
to
the
open
(up)
position.

bracket frame
5.
Open
the
microprocessor
bracket
frame
by
lifting
up
the
tab
on
the
top
edge.
Attention:
Dropping
the
microprocessor
during
removal
or
installation
can
damage
the
contacts.
Also,
contaminants
on
the
microprocessor
contacts,
such
as
oil
from
your
skin,
can
cause
connection
failures
between
the
contacts
and
the
socket.
6.
Install
the
microprocessor:
a.
Touch
the
static-protective
package
that
contains
the
microprocessor
to
any
unpainted
metal
surface
on
the
server.
Then,
remove
the
microprocessor
from
the
package.
b.
Remove
the
protective
cover,
tape,
or
label
from
the
surface
of
the
microprocessor
socket,
if
any
is
present.
c.
Align
the
microprocessor
with
the
socket.
The
microprocessor
has
two
notches
that
are
keyed
to
two
tabs
on
the
sides
of
the
socket.
A
triangle-shaped
indicator
on
one
corner
of
the
microprocessor
points
to
a
45-degree
angle
on
one
corner
of
the
socket.
d.
Carefully
place
the
microprocessor
into
the
socket.
Do
not
use
excessive
force
when
pressing
the
microprocessor
into
the
socket.
