With everyone that matter having upped and retired, leaving us kids to carry one as well as we can, I started the day pretending to be Don Borne, Data Repair. Fortunately, in his haste to depart, he left THE BOOK -- his binder with all of his notes.
The trouble ticket said to replace the power supply on an AJ modem. Arriving at the scene I found:

Checked behind the case where the power attaches -- all clear. Place a small screw into the modem case, just up and left of the power attachment. Run a small wrap-tie around the screw and power cord, holding it snug. The cord cannot come out without first cutting the wrap-tie.
