I have a SWM16 with the PI connected to its' power in port, the Genie on SWM1 out, and 3 HR2x on SWM2 out. I need to replace the barrel connector in the line at the Genie wallplate (upgrade to blue center type). While I understand I should depower the Genie before doing this, is it necessary to depower the PI/SWM? Doing so means a trip to the attic, which I'd like to avoid, but will do if needed to keep from potentially damaging that or other equipment.
Thanks in advance for any and all advice and suggestions; they are greatly appreciated.
