For starters, this first device of the RB5009 series is equipped with 9 ports: 7 1G Ethernet ports, a 2.5G Ethernet port, as well as a 10G SFP+ cage, all of which run through a powerful switch-chip and connect to the CPU via a 10 Gbps full-duplex line.
The RB5009UG+S+IN utilizes the advanced ARM 64bit CPU architecture for its QuadCore 1.4 GHz processing unit. It has a 1GB RAM and 1GB of local storage. On top of that, it comes with a Type A USB port to rid you of any storage limitation concerns.
Furthermore, thanks to the novel rear-design of its case and the location of the CPU and the switch-chip of the RB5009 at the bottom of the board, this hardware's case acts a massive heat-sink and provides a highly effective passive cooling!
