After contacting Netgear Support, I still haven't been able to determine which model is older. I did get their price for the 5V adapter (the switch I bought was missing the power supply), but I want to rig up a 5V source and make sure that the switch works before buying a power supply for it. Out at the swapmeets, I constantly run into 5V AC adapters, but nothing in the 5A range.
