I have an outdoor installation, the electrician is wondering why random signal issues are popping up on various parts of the project - 15084496. Some of it has been water intrusion, but not all his problems are related to that. Before I blame the fixtures, I'd like to know what I might expect on a rack mounted 4-port gateway if it had too much voltage on a line. Would one port fail, or a whole gateway? Particularly since I'm recommending changing to a spare port on the same gateway to test output to full.
