moving TV to different room... - DirecTV

This question is about "moving TV to different room...", with DirecTV channels, programming, equipment, and sports. I need to relocate main TV to different room, but the SWiM Power Inserter is plugged into the wall with a cord that has a tag on it saying, "Direct TV Do Not Disconnect", and it appears that I have to disconnect in order to move TV... Please advise.
And what happens if this power cord is disconnected, or if the power goes out?
