Oh, I didn't realize the Apex 3 has built in FMM ports. So it sounds like you went to the Modules screen and clicked on the FMM_X module and in the configure dropdown, selected Delete? If so, I would think you could click on the + button on the Modules screen to add it back. If you are seeing the FMM Module but not the actual ports, then you may just need to change the port to a different kind such as Optical, save it, and then flip it back to LLS. Another possibility is that the switch tiles are there but just have to be re-added to your dashboard by clicking on the padlock icon and then dragging them back down to the desired location with all your other tiles.
