MikroTik netPower 15FR is a reverse PoE switch with 16x 100Mbit ethernet ports, two SFP ports, DC power connector and two operating systems (ROS and SwOS). The first 15 LAN ports allow power through PoE IN and 16th port supports PoE out to power other devices, such as CPE antenna, camera or switch. The advantage of reverse PoE is independence from one power supply. You can power switch with up to 15 power adapters via PoE IN at the same time, but only one power will be active at a time. In case of failure it will be automatically switched to the next possible one.
