[X1-X2] X1 being installed, what does an X1 install entail

I've decided to pull the trigger on the X1 and get rid of DirecTV. Other than hooking up the receivers, installing a MoCA filter, and checking signal level, what else do they do in an X1 install. Wiring is in place, all I have to do before the installer arrives is disconnect the DirecTV receivers, and switch over the coax lines to a Comcast splitter (which I have lying around) from the DirecTV splitter and unplug the SWiM power inserter (as I'll no longer use it). -- Stop the Comcast-Time Warner merger, I'd rather Time Warner buy out Comcast.
