You can test the quality of copper cables, connectors and terminations attached to each unit. For this, the unit uses Time-Domain Reflectometry (TDR). You can quickly find opens, shorts, cable impedance mismatches, bad connectors and termination mismatches. If no problem in the cable is found, this test reports the cable length. If a problem is found, the test reports the distance at which the problem is detected.
Note: You can only test cables in use on RJ45 ports. SFPs (optical or electrical) are not supported.
To test the quality of a cable and view results
Access the page Port ▶Cable.
A summary of all cable test results for all available copper ports is displayed. For more information on specific parameters, refer to the following table.Click the Connector to test a cable.
Click the Perform test button to start the test.
The test should last only a few seconds and the status of each channel is updated as the tests are run.
