This section covers the installation of the Encore/ST G4 into Power
Mac AGP Graphics and Gigabit Ethernet models. If you are install-
ing this product into a Digital Audio model, skip to page 7. If you are
installing this product into a QuickSilver 2001 or QuickSilver 2002
model, skip to page 12.
Shut Down and Open Computer
1. Shut down your Power Mac. If the computer has been on, allow
20 minutes for it to completely cool before beginning the instal-
lation.
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.
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, do so 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, grasp one of the clips securing the
heat sink with needle-nose pliers, between the heat sink and proces-
sor card. Pull down and away to unhook one side of the clip from the
processor card (Figure 6). 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.
