I don't get it. If you have 400 cables laid into a data rack, are you going to stick a probe in that massive bundle to find cable number one, and then repeat that process over and over?
From day one of my training we were taught to mark each cable with a sharpie in 2 places, then write that number on the box. Then we pulled the cables, cut them to length and marked the other end in the same fashion.
