Behind my entertainment center you will find a variety of cords running to power bars. Pulling the wrong one when changing something can start a chain reaction of having to reset everything.
I use labels of any kind or masking tape to write big on, and label the end of the cord, 3 inches before the power bar so I can read what it is I am searching for, needing to check or unplug. Saves so many headaches and time undoing mistakes!
