Cable Test
The Cable Test screen 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.
To test cables:
1. Click Maintenance > Troubleshooting > Cable Test. The Cable Test screen displays:

• Test Result – Displays the cable test results. Possible values are:
