Running Cable Diagnostics

The Diagnostics page contains links to pages for performing virtual cable tests on copper and fiber optics cables.To open the Diagnostics page, click System → Diagnostics in the tree view.

Viewing Copper Cable Diagnostics

The Integrated Cable Test for Copper Cables page contains fields for performing tests on copper cables. Cable testing provides information about where errors occurred in the cable, the last time a cable test was performed, and the type of cable error which occurred. The tests use Time Domain Reflectometry (TDR) technology to test the quality and characteristics of a copper cable attached to a port. Cables up to 120 meters long can be tested. Cables are tested when the ports are in the down state, with the exception of the Approximated Cable Length test. The cable length returned is an approximation in the ranges of up to 50 meters, 50m-80m, 80m-110m, 110m-120m, or more than 120m. The deviation may be up to 20 meters.

To open the Integrated Cable Test for Copper Cables page, click System→ Diagnostics→ Integrated Cable Test in the tree view.
