USG FLEX 200 V5.37(ABUI.2)

So had a power cut that my UPS could not keep everything running then when power come back the SFP looked dead after checking which is connected to a NETGEAR GS110T things I did.

Reboot FLEX from UI no help

Reboot GS110T no help

Unplugged the power for FLEX and plugged back in SFP lights up and working

During the period of SFP not working, you can collect the console log when plugging into the SFP port, it would print out logs for our investigation.
However, you already recovered it by power cycling, we cannot check further. Anyway, you may collect them if anything happens.
Anyway, I suspect it's affected by static electricity, SFP is sensitive to static electricity. That's why you need a power cycling.
