NETWORK INTERFACE WITH CABLE TRACING

A network includes a network switch and plural remote nodes, each connected by a cable or channel with the network switch. The network switch includes a set of channel interfaces, each of which includes a visual indicator responsive to data traffic on the associated channel. A cable tracing arrangement includes a tracing signal generator at a channel interface of each remote node, which generates a tracing signal when cable tracing is desired. The tracing signal, when generated for cable tracing, flows over an existing cable to the associated channel interface of the network switch. At the associated channel interface, the tracing signal is converted to a visual illuminator drive signal, which illuminates the visual indicator of the channel with an indication that is distinguishable from the data traffic indication.
