mounting posts on the logic board, and confirm the connectors
on the Duet and the logic board are engaged

nectors are completely coupled by gently pulling up on the edges

Duet card snugly to the logic board ; do not overtighten the
screws (Figure 26).
5. Replace the plastic shroud on top of the Duet card (Figure 27).
