Upgrades and Options

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 fit easily, do not force it into the socket.

5. Push ZIF socket lever down (G) until it snaps into

the locked position.

6. Remove the protective paper from the adhesive side

of the heat transfer pad (F). Align the pad with the

raised position on the bottom of the heat sink (E)

and press the adhesive side of the pad onto the

bottom of the heat sink.

7. Position the heat sink above the processor so the

retention clip (D) aligns with the tabs on either side

of the ZIF socket. Engage one end of the retention

clip over the tabs at the base of the socket and press

the other end of the retention clip over the other

socket tab.

8. Locate the DC to DC converter board. The board

connector is keyed so it can only be inserted one

way. Position the board over the socket on the board

and press down evenly on the board until it seats

correctly.

9. Record the processor in the equipment log.

10. Install the CPU board back into the system as

described later in this chapter.

2. Push one end of the heat sink retention clip (Figure

5-11,.D) to release the clip from the tabs on the ZIF

socket. Remove the heat sink.
