Cable Diagnostics Test
Tools > Cable Diagnostics
The switch provides a basic cable diagnostic tool in the GUI for verifying
the pairs in copper cabling and estimated distance for troubleshooting
purposes.
Note:
If the cable length displays N/A, it means that the cable length is Not Available. The
may be due to the port being unable to determine the estimated cable length. If
length is displayed as "N/A" it means the cable length is "Not Available". This is due
to the port being unable to obtain cable length/either because its link speed is 10M
or 100M, or the cables used are broken and/or of bad in quality.
The deviation of "Cable Fault Distance" is +/- 2 meters. No cable may be displayed
in the table when the cable is less than 2 meters in length.

the distance from the switch.
