Viewing Integrated Cable Tests
The
Copper Ports 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 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 100 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.
