120Le Pentium III Processor Installation 3
Introduction
This Intel® Pentium® III Processor Installation Insert provides information for
installing the Pentium III processor upgrade into your 120Le 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. Also, you must install a VRM into the VRM
socket on the system board.

Opening and Removing the Front Door (Tower Version)
You must open the front door to remove the left side panel on your system.
Perform this procedure to open and remove the front door.
1. Power off the system and ensure the power cord is unplugged from the AC
wall outlet.
2. If the front door is locked, unlock it.
3. Grasp the indentation located on the right edge of the front door and pull the
door towards you to open it (Figure 1).
Figure 1. Opening the Front Door
4. To remove the front door, open it and lift the door and pull it towards you
(see Figure 2). The mounting pins of the front door are disengaged from the
mounting holes on the front of the system.
Figure 2. Removing the Front Door

120Le Pentium III Processor Installation 5
Removing Side Panel
To install options in your system, you must remove the side panel on the left
side of the system (as viewed from the front).
!
CAUTION
For proper cooling and airflow, do not operate the system
with the side panels removed. Always replace the panels
before powering on the system.
!
WARNING
If you are removing the side panel after the system is set up,
you must first power off the system and all external devices
and then Unplug the system power cord
To remove the left side panel:
1. The left side panel is secured to the chassis with one thumbscrew
(Figure 3, A). Remove the screw securing the side panel. Save the screw for
reattaching the side panel.
2. Using the indentation on the side of the panel, slide the side panel toward the
front of the system. This unlocks the locking fingers behind the side panel.
3. Pull the side panel out and away from the chassis (Figure 3).

Removing the Air Duct
To install processor upgrade into your system, you must remove the system air
duct. See Figure 4.
!
CAUTION
For proper cooling and airflow, do not operate the system
with the air duct removed. Always replace the air duct and
the side panels before powering on the system.
To remove the air duct:
1. Pull the air duct plunger (Figure 4, B) to release the air duct from the system
chassis.
2. Pull the air duct out and away from the chassis (Figure 4, A).

Figure 4. Removing the Air Duct
Installing the Processor Upgrade
1. Raise the secondary processor socket ZIF lever to the up position. See
Figure 5.
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 5, 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 6.

!
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 7.
Figure 7. 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 positioned as shown and is held firmly in place. If the heat
sink should slide across the top of the processor, the thermal
pad may be damaged. In the next step, the heat sink must
be gently lowered onto the processor, being careful not to
move the heat sink from side to side.

120Le Pentium III Processor Installation 9
9. The bottom of the heat sink is not completely flat, and instead has an L-
shaped groove along two sides of the bottom. Position the heat sink over the
processor so that the long side of the groove covers the rear plastic edge of
the socket and the adjacent side of the groove covers the socket lever. See
Figure 8. Gently lower the heat sink onto the processor, being careful not to
move the heat sink from side to side.

Installing the Air Duct
1. Position the air duct covering the front and rear system fans.
2. Position the air duct tabs (Figure 4, C) into the slots in the chassis rear panel.
3. Position the air duct plunger (Figure 4, B) over the locking hole in the
chassis and push the plunger inwards to secure the air duct to the system
chassis.
Installing the Side Panel
1. Before replacing the side panel, make sure no tools or loose parts have been
left inside the system chassis.
2. Make sure all option boards are firmly seated in their respective slots and
that all interior cables are properly connected.
3. Insert the metal tabs on the top and bottom of the side panel into their slots
on the chassis. Slide the side panel rearward as far as it will go.
4. Replace the side panel retaining screw (see Figure 3, A).
Installing the Front Door
1. Position the front door so the mounting pins of the front door are aligned
with their mounting holes on the front of the system. See Figure 2. Slide the
lower mounting pin into its mounting hole and then slide in the upper pin.
2. Close and lock the front door.
3. Plug in the system power cord, and turn on the system.

Checking the CPU Temperature
The EXPRESSBUILDER CD-ROM, shipped with your system, includes the
Iciser Lite Diagnostic Program. Perform this procedure to run Iciser Lite and
verify the CPU you installed is operating at the correct temperature.
1 Insert the EXPRESSBUILDER CD-ROM into the CD-ROM drive and
power up the system.
2 Select and execute the Iciser Lite Diagnostic Program.
3 View the CPU temperature indication display (Figure 12) and ensure the
following temperature indications are within range:
!CPU2 Temp does not exceed the ambient temperature by more than 30°.
!CPU2 Temp does not exceed CPU1 Temp by more than 10°.
If the CPU2 Temp exceeds either of the ranges noted in this step, it is
assumed the heat sink or thermal pad is installed incorrectly. Proceed to
Step 4.
If the CPU2 Temp is within specified ranges, proceed to Step 8.
Figure 12. CPU Temperature Display Window
4. Press Ctrl + Alt + Delete to abort the diagnostics.
5. Press Q when the target scope appears, and select shutdown to power off the
system.
6. Double check to ensure the thermal pad and the heat sink were installed
correctly. Correct problems as necessary. Then proceed to Step 7.

CAUTION
When replacing the thermal pad, remove the old thermal pad
completely from the CPU and the bottom of the heat sink.
Always replace the thermal pad with a new pad.
7. Repeat this procedure if you installed a new thermal pad or adjusted the
position of the heat sink. Once the CPU2 Temp is within the ranges
specified in Step 3 of this procedure, perform the next step.
8. Verify POST has not displayed any error messages. If POST error messages
are displayed, refer to the POST Error Codes and Messages table located in
Chapter 5 or your system user’s guide.
