We attempted to relocate a mini to a different room. In the process, I think the power supply to the multiswitch may have been unplugged. I'm not positive, but that's all I can come up with. Genie is showing 775, minis not connecting, and I don't know what to do now. Anytime I try to repeat setup, I get "SWM not detected." Will this require a service call?
