  7. Insert option card into the slot above the existing card, lining up the screw holes with the standoffs.
  8. Using the supplied M3 screws, screw the board into the standoffs, and the option plate into the chassis, applying a torque of 0.9 Nm/8.9 in-lbs.
  9. Take the supplied 50-pin ribbon cable and carefully press it into the connector on the mainboard (lining up the red sided end of the cable with PIN 1 on the mainboard), then into the connector on the option card (see Figure below).
