All the ports are now Gigabit Ethernet ports. There’s PoE-in on the first port. You can use it instead of the DC jack to power the unit. And there’s PoE-Out* on the last port – for powering other devices. Another helpful addition is an SFP cage that supports both Gigabit and 2.5 Gigabit connectivity. We have tested a variety of MikroTik SFP modules and cables that support higher speeds – the 2.5G capability makes a sysadmin’s life so much easier– there’s a console port for quick direct-access configuration!
