Unmanageable Gigabit PoE switch from TP-Link with (9) 10/100/1000 Mbps and one optical SFP port. From the Ethernet ports, port No. 9 serves as an uplink, ports 1-8 support PoE out with the 802.3af/at standard (up to 30W/port) and are intended for power supply IP cameras, Wi-Fi access points, VoIP and many other devices with a total PoE budget of 61W.
The switch also enables PoE at a distance of 250m (ports 1-4) when switching a special switch that causes the line speed on the PoE ports to decrease to 10 Mbps, which for transmission the image from the cameras is more than enough. Another bonus of the switch is the switch for PoE Auto Recovery (ports 1-8) ensuring automatic power restart for elements that stop communicating. The last switch is Port isolation (ports 1-8), to determine the communication of end elements only with the uplink port.
