14.2 Viewing Integrated Cable Tests
The Copper Cable Page contains elds 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 Reectometry (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 view cable test results:
Click System > Maintenance > Diagnostics > Copper Cable. The Copper Cable Page opens:
