The cable diagnostic feature is designed primarily for administrators or customer service representatives. It is used to test and verify copper cables; it can quickly determine the quality of the cables and the types of error.

Note:
1. If cable length is displayed as N/A it means the cable length is Not Available. The cable length is undetermined because either the link speed is less than 1G or the cables are broken and/or bad quality.

2. The deviation of "Cable Fault Distance" is +/- 2 meters. No cable may be displayed under Test Result when the cable is less than 2 meters in length.

3. The test also measures cable fault and identifies the fault in length according to the distance from this switch.
