Dear friend!
What is the model of the product that reports the alarm? Is it a transmission network device?
If yes, please perform the following operations:
1. Check whether optical cable disconnection and other alarms are generated on the line. If yes, clear the alarms.
2. Check whether the NE that the Ethernet link traverses works normally. If protection switching is triggered due to equipment and line exceptions, check whether the switching is successful.
3. Check that your Ethernet service link configuration is correct. For example, whether the trail is complete and Ethernet-related parameters (MTU/VLAN value/Port attribute/Working mode) Check whether the settings are correct.
Thanks！

Welcome dear
As shown from your attached photos I think that 3G cells down also so plz act as below
-Log in LMPT by your laptop and get an IP of 3G
-Now set your lap IP to 3G IP
-Remove Ethernet cable from LMPT of 3G and connect it to your laptop
-Call BO TX and ask Ping on 3G of that site if it's pingable then replace LMPT and if not pingable then go to B/M
-Let BO check on all configurations specially VLAN.

Note LED status is important but in some cases, you shouldn't build your troubleshooting on it.


please F.B, if ur problem solved or still to, can help you
