Test cable connections
You can use the cable diagnostic feature to easily find out the health status of network
cables. If any problems exist, this feature helps quickly locate the point where the cabling
fails, allowing connectivity issues to be fixed much faster, potentially saving technicians
hours of troubleshooting.
If an error is detected, the distance at which the fault is detected is stated in meters.
(This is the distance from the port.)
To test cable connections:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired network connection, or connect directly to a switch that
is off-network using an Ethernet cable.
2. Launch a web browser.
3.
In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Access the switch using a web
browser on page 7.
The login page displays.
4. Enter the switch password.
The default password is password. The password is case-sensitive.
The Switch Information page displays.
5. Select System > Monitoring > Cable Tester.
