The following notes describe the type of microprocessor
that the server supports and other information that you must consider
when you install a microprocessor and heat sink.
Note: If your server comes with one Intel Pentium 1400 series
microprocessor, the second microprocessor socket is not used. The
server supports only one Intel Pentium microprocessor. If you plan
to install two Intel Xeon microprocessors in the server, you must
first remove the Intel Pentium microprocessor that came with the server.
To install an additional microprocessor and heat sink,
complete the following steps:
- Read the safety information that begins in Safety and Installation guidelines.
- Turn off the server (see Turning off the server) and all attached
peripheral devices. Disconnect all power cords; then, disconnect all
external cables from the server.
Attention: When you handle static-sensitive devices,
take precautions to avoid damage from static electricity. For details
about handling these devices, see
Handling static-sensitive devices.
- Remove the top cover (see Removing the server top cover).
- Remove the air baffle (see Removing the air baffle).
- Locate microprocessor socket 2 on the system board.
- Remove the heat-sink filler, if one is present.
- Open the microprocessor socket release lever and retainer.
- Press down and out on the release lever on microprocessor
socket 2 and lift up the microprocessor release lever until it stops
in the fully open position.
- Lift the hinged microprocessor bracket frame into an
open position.
Attention: When you handle static-sensitive devices,
take precautions to avoid damage from static electricity. For details
about handling these devices, see
Handling static-sensitive devices.
Figure 1. Lift the bracket frame into an open position
- Install the microprocessor:
- Remove the socket cover from the microprocessor socket.
Figure 2. Microprocessor Installation
- Touch the static-protective package that contains the
new microprocessor to any unpainted metal surface on the server.
- Remove the microprocessor installation tool assembly
from the package. The microprocessor installation tool assembly comes
with the microprocessor and microprocessor cover attached to the tool.
The microprocessor comes protected between the tool and the microprocessor
cover.
Attention:
- Do not rotate the handle on the tool until you are ready to install
the microprocessor into the microprocessor socket.
- Do not touch the microprocessor contacts; handle the microprocessor
by the edges only. Contaminants on the microprocessor contacts, such
as oil from your skin, can cause connection failures between the contacts
and the socket.
- Handle the microprocessor carefully. Dropping the microprocessor
during installation or removal can damage the contacts.
- Remove the cover from the bottom of the microprocessor
installation tool. Press both microprocessor cover release tabs outward
(in opposite directions as shown in the illustration) and remove the
microprocessor installation tool with the microprocessor attached.
Figure 3. Microprocessor removal with microprocessor installation tool
- Carefully align the microprocessor installation tool
over the microprocessor socket. .
Note: The microprocessor fits only one way in the socket.
Figure 4. Microprocessor installation alignment
- Twist the handle on the microprocessor tool counterclockwise
to insert the microprocessor into the socket.
Figure 5. Microprocessor insertion
- Take off the microprocessor installation tool from the
microprocessor socket and close the microprocessor bracket frame.
- Carefully close the microprocessor release lever to
the closed position to secure the microprocessor in the socket.
- Install the heat sink that came with the microprocessor:
- Remove the plastic protective cover from the bottom
of the heat sink.
Attention: Do not touch the thermal grease on the
bottom of the heat sink after you remove the plastic cover. Touching
the thermal grease will contaminate it. See
Thermal grease for more information.
- Align the screws on the heat sink with the screw holes
on the system board; then, place the heat sink on the microprocessor
with the thermal-grease side down.
Figure 6. Heat sink placement
- Press firmly on the captive screws and tighten them
with a screwdriver. The follow illustration shows the sequence in
tightening the screws, which is also shown on top of the heat sink.
Begin with the screw labeled as "1", then "2", "3" and finally "4".
If possible, each screw should be rotated two full rotations at a
time. Repeat until the screws are tight. Do not overtighten the screws
by using excessive force. If you are using a torque wrench, tighten
the screws to 8.5 Newton-meters (Nm) to 13 Nm (6.3 foot-pounds to
9.6 foot-pounds).
Figure 7. Sequence in tightening the screws
- If you installed the second microprocessor, install the
two fans on Fan connector 4 and Fan connector 6 of the system board
respectively (see Replacing a fan).
- Reinstall the air baffle, (see Replacing the air baffle).
- Reconnect any cables that you have disconnected from the
adapters or system board.
