      44 The cable plant for your company network was installed several years ago by an outside contractor. Now, some of the paper labels have fallen off your patch panels, and you do not know which wall plate is connected to each port. Assuming that you are working on a properly maintained and documented network installation, which of the following is the easiest way to determine which port is connected to which wall plate?Consult the cable diagram provided by the cabling contractor at the time of the installation.Call the cable installation contractor and see if he or she can remember which ports go with which wall plates.Attach a tone generator to a patch panel port and then test each wall plate with a locator until you find the correct one. Repeat this for each port that needs labeling.Use a cable certifier to locate the patch panel port associated with each wall plate port.
