This section covers the installation of the Encore/ST G4 Duet into
Power Mac G4 AGP Graphics and Gigabit Ethernet models. If you are
installing this product into a Digital Audio model, skip to page 6. If
you are installing this product into a QuickSilver 2001 or QuickSilver
2002 model, skip to page 10.
Shut Down and Open Computer
1. Shut down your Power Mac. If the computer has been on for a
while, allow 20 minutes for it to completely cool before begin-
ning 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 to the computer and an
electrical outlet.
3. Touch a port access cover on the back of the computer (Figure 4)
to discharge any potentially damaging static electricity.
4. Disconnect the power cord from the computer.
5. Locate the security lock at the back of the computer (Figure 5).
If it is not already pressed in, press it in now.
6. 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 6).
Remove Heat Sink
Locate the processor heat sink on the logic board (Figure 7); your
heat sink may appear different from what is pictured. Using caution
to avoid touching the processor card and the logic board, grasp one
of the clips securing the heat sink with needle-nose pliers, between
the heat sink and processor card. Pull down and away to unhook one
side of the clip from the processor card
(Figure 7). Push the clip away
from you to unhook it from the other side. Repeat these steps with
the other clip. Once the clips have been unhooked, gently lift the heat
sink and clips away from the processor and set them aside, but not on
the logic board.

WARNING: When handling computer products, take care to
prevent components from being damaged by static electricity;
avoid working in carpeted areas. Handle processor upgrade cards only
by their edges and avoid touching connector traces and component
pins. Also, avoid touching the logic board and any of its components.
