Remove the metal shield. Carefully pry the shield up from the top (hole vented side) first and then push out the other side to slip the port holes past the port edges. Then lift the shield up and away. Set shield aside.
Note: Be mindful of the side clips on the controller's two Ethernet ports.

Carefully pry up the FX30E/FX60E module board, noting that the two-row, 50-pin connector is on the option card side. Keep the board level as you work it loose from this connector.
