Cable Diagnostics

The Cable Diagnostics feature helps identify any connectivity problems with cabling and provides information about where errors may have occurred. The tests utilize Time Domain Reflectometry (TDR) technology to assess the quality of a copper cable connected to a port. TDR works by detecting cable faults through the transmission and analysis of a signal sent through the cable. However, it's important to note that TDR may yield different results based on the status of the port, and these results must be interpreted accordingly.

• Select any port and click Test to initiate the cable diagnostics. The result of the port is displayed.
• The result displays the local pair's status and length of the cable.
