5.
Carefully remove the cap covering the connector on the bottom
of the Duet processor card
(Figure 13)
, and then place the cap on
the original processor card’s connector.
6.
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, and the screws you removed in a safe place.
7.
Align the connector on the bottom of the Duet card with the
connector on the logic board
(Figure 14)
, and then set the card
down on top of the three threaded posts (not shown). Make sure
the connectors 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 Encore/ST board; the board
should remain fi rmly in place.
8.
Making sure the Duet card’s captive screws are engaged prop-
erly 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 15)
.
