Installation—Digital Audio Models

This section covers the installation of the Encore/ST G4 Duet into 
Power Mac G4 Digital Audio models (back panel appears like Figure 16). 
If you are installing this product into an AGP Graphics or Gigabit 
Ethernet model, go back to page 3. 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 to dis-

charge any potential damaging static electricity 

(Figure 15)

.

 

4.

 Disconnect the power cord from the computer. 

 

5.

 If present, remove the two indicated screws from the back plate 

of the computer 

(Figure 16)

. Otherwise, go to step 6.

 

6.

 Locate the security lock at the back of the computer 

(Figure 17)

If it is not already pressed in, press it in now.

 

 

7.

 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 18)

.

 

 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.

 

 Support Note:

 To avoid generating a static charge in your 

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

installing the Encore card and close the computer.
