Some remodeling was done while I was away from work, and I'm left with several unlabeled cat5 cables that are terminated with RJ45 keystone modules. On the other end, all of the cables are terminated at the patch panels in the server room.
Some of the cables are connected to the switches and are active data lines. I can verify the lines are active by plugging a laptop into the keystone modules. The DCHP server assigns an address and I'm in.
During my attempts to trace the lines using a toner and probe, I noticed that the lines that are active have a very weak tone signal. It is so weak, I can't trace it. The other lines, however, I was able to trace without any issues. Anyone know why the signal is so weak? Is it because the line is active and data packets are watering down the toner's signal?
