120Ra-1 Pentium III Processor Installation 3
Introduction
This Intel®Pentium®III Installation Insert provides information for installing
the Pentium III processor upgrade into your 120Ra-1 system. Read this
procedure in its entirety before performing the installation to become familiar
with the items in this upgrade and the sequence of steps you will perform.
Unpacking the Upgrade
When you receive your Pentium III processor upgrade, inspect the shipping
container prior to unpacking. If the shipping box is damaged, note the damage,
and if possible, photograph it for reference. After removing the contents of the
container, keep the carton and the packing materials. If the contents appear
damaged when you unpack the box, file a damage claim with the carrier
immediately.
Installing the Upgrade
!
CAUTION
Observe static precautions. Use an antistatic wrist strap.
Hold the processor only by its edges. Do not touch the pins
of the processor board.
!
CAUTION
Installing a second processor that is of a different type than
the first processor will result in system damage. Do not
touch or bend the processor's exposed pins.
Note: When adding a second processor to your system,
you must remove the terminator from the secondary
processor socket.

Removing the Front Bezel
Refer to the Figure 1 and remove the front bezel of the server as follows:
1. Terminate all applications.
2. Open the front door of the system rack.
3. If the front server bezel is locked, unlock it.
4. Grasp the right edge of the front bezel and pull the bezel towards you to
open it.
5. Slide the front bezel left to disengage the mounting tabs and remove the
front bezel from the chassis.
6. Press the power ON/OFF button (Figure 1, A) to power down the server.
7. Remove the two screws securing the server to the front of the system rack.
!
WARNING
To reduce the risk of personal injury, be careful when
pressing the component rail release latches and sliding the
component in or out of the rack. The slide rails could pinch
your fingertips.
8. Pull the server out of the rack until the component rail release latches
engage. The component rail release latches on either side of the server lock
the server onto the slide rails.

Top Covers
The server includes front and rear top covers. To install a processor into the
system board of the server, you must remove the rear top cover.
!
CAUTION
For proper cooling and airflow, do not operate the system
with the top covers removed. Always replace the covers
before powering on the system.
!
WARNING
If you are removing the top covers after the system is set up,
you must first power off the system and all external devices
and then Unplug the system power cord
Removing the Rear Top Cover
To remove the rear top cover:
1. Loosen the captive thumbscrew securing the top cover to the rear panel.
See Figure 2. Slide the top cover towards the rear of the server chassis until
its tab fasteners unlock.
2. Lift the top cover up and away from the chassis.

Installing a Processor
!
CAUTION
Observe static precautions. Use an antistatic wrist strap.
Hold the processor only by its edges.
!
CAUTION
Installing a second processor that is of a different type than
the first processor will result in system damage. Do not
touch or bend the processor's exposed pins.
Note: When adding a second processor to your system,
you must remove the terminator from the secondary
processor socket.
1. Raise the ZIF socket lever to the up position. See Figure 3.
Figure 3. Raising the ZIF Socket Lever
2. Remove the terminator from the secondary processor socket.
3. Position the processor over its ZIF socket so the processor pins align with
the socket holes. Note that one corner of the processor has three pins that
should be positioned over the corner of the socket that has the three
matching pin holes. See Figure 4, A.

4. Insert the processor pins into the socket. Apply pressure equally over the top
surface of the processor until it seats in the socket. The processor should
easily fit, do not force the processor into the socket.
5. Lower the ZIF socket lever into the locked position. See Figure 5.

CAUTION
The thermal pad is very delicate and tears easily. Handle
with extreme care. Perform the next two steps exactly as
described to ensure proper heat transfer from the processor
to the heat sink.
6. One side of the thermal pad is shiny metallic foil. The other side of the
thermal pad is covered with a clear plastic liner. Carefully peel the liner
away from the pad. The clear liner is not used and may be discarded.
7. Position the thermal pad on top of the processor with the shiny side facing
down and the yellow sticky side of the pad facing up. Ensure the pad is
positioned over the center of the processor as shown in Figure 6.
Figure 6. Installing Thermal Pad
8. Ensure the small end of the heat sink clip is positioned into the heat sink as
far as it will go.
Note: The heat sink included with this upgrade may not
resemble the heat sink on the processor in your system.
Several types of heat sinks are used with the Pentium III
processor.
!
CAUTION
When performing the next three steps, be sure the heat sink
is held firmly in position. If the heat sink should slide across
the top of the processor, the thermal pad may be damaged.

9. Attach the small end of the heat sink clip to the tab located on the base of the
ZIF socket. See Figure 7, A. Gently lower the heat sink onto the processor,
being careful not to move the heat sink from side to side.

10.Using a small flat blade screwdriver, press down on the heat sink clip
retention latch and hook it under the fastener tab on the base of the ZIF
socket, as shown in Figure 8, A. The heat sink clip is now secured to the
fastener tab of the ZIF socket.

1. Position the top cover above the server and slide the cover towards the front
of the server chassis until its tab fasteners lock into the chassis.
See Figure 9
2. Tighten the captive thumbscrew securing the top cover to the chassis.
3. Slide the server into the system rack and secure it to the rack.
4. Plug in the server power cord, and power on the server.
