I just grabbed a cheap SFP DAC off of ebay and connected the two .. I think there is some configuring to do in your edgerouter and/or Netgear switch .. but I'm at work right now so can't pull them up to look. That's the nice thing about this old Netgear switch and my edgerouter .. once you get it set up , it just works ... the downside is that I forget what I did, lol.
