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.

Figure 8. Installing Heat Sink Clip

11.Record the processor in the equipment log.
