Seeker part of the skill description:

In the room with a patch panel, if the patch panel and the jumper connection between the switch, you can directly find the jumper, you can confirm the accuracy of the initial confirmation of the cable with the other jumper separated from a few centimeters If you do not directly find the patch panel patch panel port, you can plug the receiver directly into the RJ45 interface, so you find the purpose of the line and the other (Note: because of the close distance between the ports of the patch panel, the other ports will have a faint sound generated, with the largest sound and receiver light is the brightest to locate you Look for the cable.)

(Note to determine the size of the sound, the sound is the biggest you want to find the purpose of cable, in addition to strong attention to switch interference, as far away from the switch as far as possible, so that the sound will be more clearly.)
