Performing Copper Cable Tests
The
Performing Copper Cable Tests
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 that 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.
