Double the usual performance: we took your feedback from the MikroTik User Meetings to create the perfect home lab router: compact, powerful, with multiple powering options and efficient cooling. RB5009 has it all, and even more!
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 (5.08mm 1x2pin) on the side
Boards come with 1GB of DDR4 RAM and 1GB NAND storage. This combination of ports and components, compared to our other products in a similar form factor, provides almost double the performance in configurations with heavy CPU loads.
With a simple set of mounting accessories, you can mount FOUR of these routers in a single 1U rackmount space! No more server-room-Tetris, just pure productivity.
