NOTICE
Although each port can deliver supply current of 500 mA, the overall load on USB0 to
USB3 interfaces should be limited to 900 mA to prevent power supply from overheating.
4.8 Ethernet Interface ETH0
Ethernet interface 0 is implemented by Davicom DM9102 network controller. It provides 10/100BaseT,
networking through the shielded modular jack. Twisted pair cable can be used to connect to this port.
