This device features seven Gigabit Ethernet ports, plus an eight 2.5Gbps Gigabit Ethernet port; there is also a 10G SFP+ cage for greater bandwidth requirements.
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 !
The device comes with 1GB of DDR4 RAM and 1GB NAND storage.
RB5009UG+S+IN can be powered in 3 different ways:
a) PoE-in from Ethernet port #1
b) DC Jack
c) 2-pin (telecom) terminal on the side
Lastly, with a simple set of mounting accessories, you can mount FOUR of these routers in a single 1U rackmount space !
