Install Encore/ST G4 Duet Processor Upgrade Card
1. Remove the Encore/ST G4 Duet processor upgrade card from
its anti-static package; make sure to handle the card by its edges
(Figure 22); your card may differ from what is pictured.
2. Carefully remove the cap covering the connector on the bottom
of the Duet processor card (Figure 23), and then place the cap on
the original processor card’s connector.
3. Place the processor card you removed from the computer into
the anti-static package, and then store it, the original heat sink,
heat sink clips, the screws you removed, and the fan assembly in
a safe place.
4. Align the connector on the bottom of the Duet card with the
connector on the logic board (Figure 24), and then set the card
down on top of the three threaded posts. Make sure the connec-
tors are lined up, then, grasping the Duet card by its heat sink,
gently press it straight down until the connectors snap together.
Verify the connectors are completely coupled by gently pulling
up on the edges of the Duet board; the board should remain
firmly in place.
6. Making sure the Duet’s captive screws are engaged properly in
the threaded posts, tighten each of the three screws and secure
the card snugly to the logic board;
do not overtighten the
screws (Figure 25).
