May I know how you supplied the power to this issued OC300?

Through PDU , 220V

 

Is there any difference from other sites?

No

 

Please check whether the devices got disconnected

No the rest of the system is stable.

 

or did the network on this site experienced internet access issues when these logs occurred

No, no issues were experienced, nor the log shows ISP disconnects, no end user complain.

.

Please change a short Ethernet cable to connect the OC300 to the front-end device for testing.

Cable replaced the 1Meter cable with 0.3 meter cable.

 

Furthermore to the above we also looked at our fiber cables and found out that the telephone room where the ISP cables originated from had RAT infestation and several chew marks on outdoor fiber cable were discovered in several location. I strongly believe that disruption in Omada OC300 status was caused by the rats gnawing on the cable. This was the biggest reason that this Online/Offline was more persisted during late evening hours till almost daybreak. We have taken measured to close the building Orifices left uncovered or completely open by contractors to limit and hopefully eliminate the access of the vermians to the telephone room.

 

Thank you for your support. The amount of annoying messages has since reduced to a few instances at night.
