Thanks for the quick answer, Atlantisman. I actually have already pieced together your excellent instructions with others (Steve Jenkins & Bryan Klinger) to successfully get my ER5-POE working for everything except TV service. The ER5-POE easily powers the fiber connection.
I'm stuck because the system google installed has the newer combo DVR/Modem all in one box and it seems without that somewhere in the network the TV does not work. I get the TV menu and guide on screen but when I select a channel to watch it says there's no DVR connected. Don't really need or want the DVR, just want to watch channels live but it seems google needs the DVR to be in the loop somewhere. I tried just connecting it to my LAN like any other device but cannot seem to get it an address. I'm guessing it is looking for the fiber box and won't connect without that in the loop.
