Attention: v A startup (boot) processor must always be installed in socket J22 on the system board. v To ensure proper server operation when you install an additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical. Complete the following steps to install an additional microprocessor: 1. Read the safety information beginning on page v and "Installation guidelines" on page 7. 2. Turn off the server and peripheral devices, and disconnect the power cords and all external cables, if necessary; then, remove the top cover. 3. Remove the air baffle and the microprocessor baffle. 4. Install a VRM in the VRM connector (J72). 5. Install the microprocessor: a. Touch the static-protective package containing 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 present. 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 system board. c. Rotate the locking lever on the microprocessor socket from its closed and locked position until it stops or clicks in the fully open position (approximately 135° angle). Attention: v Do not use excessive force when pressing the microprocessor into the socket. v Make sure that the microprocessor is oriented and aligned with pin number 1 in the socket before you try to close the lever. d. Center the microprocessor over the microprocessor socket. Align the triangle on the corner of the microprocessor with the triangle on the corner of the socket and carefully press the microprocessor into the socket. 20 IBM xSeries 346 Type 8840: Installation Guide

Attention:
v
A
startup
(boot)
processor
must
always
be
installed
in
socket
J22
on
the
system
board.
v
To
ensure
proper
server
operation
when
you
install
an
additional
microprocessor,
use
microprocessors
that
have
the
same
cache
size
and
type,
and
the
same
clock
speed.
Microprocessor
internal
and
external
clock
frequencies
must
be
identical.
Complete
the
following
steps
to
install
an
additional
microprocessor:
1.
Read
the
safety
information
beginning
on
page
v
and
“Installation
guidelines”
on
page
7.
2.
Turn
off
the
server
and
peripheral
devices,
and
disconnect
the
power
cords
and
all
external
cables,
if
necessary;
then,
remove
the
top
cover.
3.
Remove
the
air
baffle
and
the
microprocessor
baffle.
4.
Install
a
VRM
in
the
VRM
connector
(J72).
5.
Install
the
microprocessor:
a.
Touch
the
static-protective
package
containing
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

socket,
and
system
board.
c.
Rotate
the

socket
from
its
closed
and
locked
position
until
it
