3. Place the processor card you removed from the computer into
the anti-static package, and then store it and the original heat
sink in a safe place.
4. Place the Duet card on a flat, level surface, with the bottom of
the card resting on the piece of foam that was in the anti-static
package. Remove the four screws securing the fan assembly to
the top of the card and set them aside
(Figure 32).
5. Carefully disconnect the fan connector from the Duet card, and
then remove the fan assembly (Figure 32).
6. Remove the included heat sink cover from its bag. Using the two
large holes in the cover and two holes in the Duet’s heat sink for
reference, place the cover on the heat sink
(Figure 33).
7. Using the four screws you removed previously, attach the heat
sink cover to the heat sink (Figure 33).
8. Locate the DIP switches on the top surface of the Duet card
(Figure 34). Push both switches to the down position.
