Which cable arced, an Ethernet cable or a power cable ? An arc when connecting the dc power cord is normal – it is best to connect the AC cord after the dc cord is connected.

Connect one power supply to the mode A input and try all ports – which ones work, are there any arcs? Try again with the mode B input

If all ports work with one power supply, then try again with both.
