The managed MP310-HV switch is specially designed for fast and reliable infotainment and IP-surveillance networks on road and railway public transport. The switch provides 7 FE ports with intelligent PoE/PoE+ functionality and 3 Gigabit ports, one of which is PoE/PoE+ port and 2 Gigabit uplink ports with link bypass function ensuring network connectivity even in case of device/power fault. IP31 industrial hardware design with M12 rugged connectors eliminates the problems of vibration, shock, and temperature extremes. The switch is also equipped with M12 USB port for field configuration and trouble shooting.
