You are invited to counsel for a medium-sized company that is experiencing network connectivity problems. You note that none of the dozens of UTP cables on the patch panel are labeled. Which tool can you use to determine which cable is connected to which workstation?

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.
