Network Cable Tracer for Live Network?
Posted on 2007-04-01
Occassionally I get called to troubleshoot equipment on an unfamiliar network and when I get there, I find that none of the cables in the wiring closet are identified or marked in any way. In these cases, there is no way to tell which cable on a switch or router goes to what jack in a particular office. It would be great if I could just plug some kind of a testing device into the RJ45 jack in the office and then use a tone tester at the router or switch on the other end to find the associated cable. Is anyone aware of a network cable tracer / tone tester that can be used on a live connection, i.e., while plugged into a router, switch, hub, etc?
