The board features 9 wired ports and a full-sized USB 3.0. Seven of the ports are Gigabit Ethernet, another one is 2.5 Gigabit Ethernet, and the last one is a 10G SFP+ cage. All the ports are connected to a powerful Marvell Amethyst family switch-chip with a 10 Gbps full-duplex line leading to the Marvell Armada Quad-core ARMv8 1.4 GHz CPU. Both CPU and the switch-chip are located on the bottom of the board – so the case acts as a massive heat-sink!
RB5009UG+S+IN can be powered in 3 different ways:
a) PoE-in from Ethernet port #1
b) DC Jack
c) 2-pin terminal on the side
