GPON inaccessible after setting ISP's serial number #32

Stick got absolutely ruined after I set S/N according to the manual and typed reboot. It never came back, 192.168.1.10 is not reachable anymore, nothing helps. Flashed firmware version 3FE46398BGCB22

With or without fiber, stick is no longer accessible. Sometimes it passes 1-2 pings for a second after fiber inserted and then stops. How to recover from this?

Router is Mikrotik (v7). Screenshot 2023-04-13 at 7 16 42 PM

UDP: I was able to access it in TP-LINK Media converter MC220L (also put a rubber placeholder in the GPON prior to inserting it, not sure it it reflects some waves back but it worked). FW was reverted itself to image1, I flashed it in image0. Why did it revert itself?

The rubber plug is only to protect against dust.

The Mikrotik may check the Rx_LOS signal, so it would only enable the fiber is plugged. The MC220L doesn't do the check.

Setting the SN might break the management link when the fiber is plugged if the OLT changes the configuration (disabling it, or moving it to another VLAN, or causing a bug).

Did you flash first, or did you flash and set the SN at the same time ? The revert to the older firmware might be due to a boot failure, but this is strange.

I have flashed new firmware, rebooted fine and then set SN and rebooted again and then lost access, after several attempts I was able to recover access via media converter but firmware booted appeared to be stock one, so I flashed a different version (not 22) to another partition again and rebooted in it fine. Odd.

So with 3FE46398BGCB22, either there is an issue with the configuration pushed by the OLT, or it disables or moves the CPU port to another VLAN.

Which version did you flash next ? I suppose you still have O5, but still having access after plugging the fiber might be good or bad depending on the cause (maybe it fails before).

I have this issue as well with 3FE46398BGCB22. Any idea what is the VLAN it moves to @hwti ? I onnthe MC220L I can see SFP is connect but unable to ping. I think with the right VLAN I will be able to access it if that is the case.
