Hunt part of the skills introduced:
In the case where there is a patch panel in the equipment room, if there is a jumper connection between the patch panel and the switch, you can find the jumper directly. To confirm the accuracy, you can separate the target cable from the other jumper by a few centimeters Of the distance, issued a very loud voice, that is correct; if there is no jumper directly find the patch panel port, you can put the receiver probe directly into the RJ45 interface, so you want to find the destination line and other (Note: Because the distance between the patch panels is very close, so the other ports will have a weak sound, with the largest sound and receiver light to the brightest to locate your Find the cable.)
(Note to determine the size of the sound, the sound is the most you want to find the purpose of cable, in addition to pay attention to the switch strong electric interference, as far as possible away from the switch, so the sound effect will be more clear.
