5. Holding the Duet by its bracket, insert the edge of the card into
the support bracket between the spring clips and plastic tabs, and
lay the card down
(Figure 11).
6. Verify the screw holes on the Duet’s bracket are aligned with
the mounting posts and bracket on the logic board, and confirm
the connectors on the Duet and the logic board are engaged
(Figure 12).
7. Gently press straight down on the heat sink as shown
(Figure 13) until the connectors snap together. Verify the con-
nectors are completely coupled by gently pulling up on the edges
of the Duet board; the board should remain firmly in place.
8. Verify again that the screw holes on the Duet’s bracket are
aligned with the mounting posts and bracket on the logic board,
and if necessary, move the Duet’s bracket to fix the alignment.
9. Using the four screws you removed earlier, secure the Duet to the
logic board; do not overtighten the screws (Figure 14).
