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