Check if fiber is working. :)
If it is not OK swap cables on one side of cable (Rx and Tx pair).
Additionally, (I am not familiar with netgear) maybe you have dual-personality port so you may need to manually configure port to use SFP and not RJ45 port.
I clicked through the settings in the switch and couldn't find any kind of dual-personality port settings.
Port status for the two SFP shows "down".
When configured,
Switch<-->Switch<-->Router<-->PC So the 2 switches are connected to via CAT5e, 1 switch connected to the router, i can ping both switches. The PC is connected to the router.
The LC to ST connectors had mislabeled lines. When i swapped one side of my connection, it solved the issue. This was after i went through 3 sets of SFPs.
