4-3 Cable Diagnostics
This page is used for running the Cable Diagnostics for 10/100 and 1G copper ports.
Press Start to run the diagnostics. This will take approximately 5 seconds. When completed, the page
refreshes automatically, and you can view the cable diagnostics results in the cable status table. Note that
Cable Diagnostic is only accurate for cables of length 7 - 120 meters with 5-meter accuracy.
The 10 and 100 Mbps ports will be linked down while running Cable Diagnostics. Therefore, running Cable
Diagnostics on a 10 or 100 Mbps management port will cause the switch to stop responding until Cable
Diagnostics is complete.
