Do you still have the full node drive plugged in? Make sure you remove it to be sure thats not causing the issue. That loop also sounds like it cant detect the hashboard. Make sure the controller is properly seated in its socket on the backside.
usb drive is disconnected and hasboard sitting rock solid in it's socket.
still the same behaviour. orange light comes on 4 times together with the fan and that's it.
after like 20 times trying I was lucky and managed to establish a ssh connection.
the unit reset connection on it's own. afterwards froze again and I am not able to re-connect d/t connection timed out
C:\Users\admin>ssh futurebit@192.168.1.222
