For anyone curious, you can turn these A4+'s into A6s. The control board has enough ports for 8 hashboards and 4 fans. I changed over 30 A4s so I only have to monitor 15 ASICs now. Way better. The inno support guy gave me an older firmware that supports it, the latest only ran 6 boards total. He said there should be a new firmware today or tomorrow that supports all 8 again.
