Question:
A tone generator and probe are the best tools for tracing a wire in a wall from one spot to another. Attach one end to one end of the cable, such as the end at the computer, to utilize it. Then, using the other end of the probe, go to the patch panel to locate the cable. When the cables are not properly labeled, these tools can help you out. A cable tester is used to ensure the integrity of a cable and that it is properly wired. A network interface card (NIC) is tested using a loopback plug, and wires are terminated into a patch panel using a punchdown tool.
