I can tell you the Mimosa unit is the only one I've found that works correctly with the C5. Maybe I was sent a standard voltage model of your GigE SS, but I had Ethernet link issues with it as well. I ordered the HV model, but didn't see anywhere it said, so I assumed the disty sent the wrong item. Maybe the HV would work fine.
