Viewing Copper Cable Diagnostics
The
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.
