Packing reliable performance into a small form factor, the RB5009UPr+S+IN 8-Port Multi-Gig PoE Router from MikroTik features seven Gigabit speed Ethernet ports and one 2.5 Gigabit Ethernet port, all of which are equipped with PoE input and output. There is also an SFP+ slot for up to 10 Gb/s fiber connections.
A 1.4 GHz Quad-Core processor is located at the bottom of the board alongside the switch chip, using the entire chassis as a massive heat sink to maintain optimal performance, alongside 1GB of RAM and 1GB of NAND storage. You can power this router by connecting the first port to a PoE compatible device, through the 2-pin terminal block, or using the included AC power adapter. You can mount the RB5009UPR+S+IN onto a wall or rack, with up to four able to fit in 1 RU of space. Use the RouterOS operating system to manage its settings.
What about the PoE-out devices? Once again, the highest voltage wins. PoE-out devices will draw power from the 48V source on the 2-pin connector. If that fails, the 24V on the DC jack come into play. The board will always reserve 20 watts to power itself. If there is not enough power for all the PoE-out ports, it will start disabling the ones with the lowest priority. You can set the port priority manually.
