Hardware Installation—G3 Blue & White, G4 PCI Graphics

This section covers the installation of the Encore/ZIF G4 processor
upgrade card into Power Macintosh G3 Blue & White and Power Mac
G4 (PCI Graphics) systems (and equivalent servers). If you have a
Power Macintosh G3 Desktop computer, return to page 2. If you have
a Power Macintosh G3 Minitower or Macintosh Server G3 system, go
back to page 7. If you have a Power Macintosh G3 All-in-one system,
go back to page 12.

Shut Down and Open Computer

1. Shut down your Power Macintosh. If the computer has been on

for any length of time, wait a few minutes for it to cool before
beginning the installation.

2. If you need to move the computer to a different area where you

can work freely, disconnect any connected cables, move the com-
puter, then reconnect the power cord and plug it in to an outlet.

3. Locate the security lock at the back of the computer (Figure 65).

If it is not already pressed in, do so now.

4. With the right side of the case facing you, open your Power Mac

by lifting the release latch and lowering the side panel away from
the computer’s case

(Figure 66).

5. Touch the power supply case (Figure 67) to discharge any poten-

tially damaging static electricity, then disconnect the power and
peripheral cables from the back of the computer.

Remove Heat Sink—G3 Blue & White

This section explains the process to remove the processor heat sink
in a Power Macintosh G3 Blue & White system. If you have a Power
Mac G4 (PCI Graphics) system, skip to “Remove Heat Sink—G4 PCI
Graphics” on the next page.

1. Locate the screw securing the heat sink ground wire to the logic

board

(Figure 68). Remove the screw, move the wire out of the

way, and then replace the screw;

do not overtighten it.

Support Note:

To avoid generating a static charge in your

body, do not walk around the room until after you finish in-

stalling the Encore/ZIF card and close the computer.
