XMG1915-10EP -can't connect to switch

Hi @MrStranger

Thanks for the information about the system LED status. It confirms that the switch doesn't get stuck in the booting process.

Could you help to take these actions to verify?

1. Reboot the switch.
2. Isolate the switch and connect one PC.
3. Set the PC's ip address to 192.168.1.x
4. Ping the 192.168.1.1.
5. Use 192.168.1.1 to access it.

If you can't access it:

1. To have further checking, we need to use a 4-pin console to access the switch. May I know if you have a 4pin console?

If you can access it:

1. Please help to fix the IP address of switch and keep isolate for 12 hours at least to verify if it is still accessible. Also, please share your network topology and all devices with us to understand your network.
2. Connect back to the network and monitor this issue.
3. If the issue happens again, please isolate the switch and check if you can access.

P.S. Zon is working on MAC based.
