DS306 is an industrial L2 smart managed Ethernet switch equipped with 4 Gigabit Ethernet ports with 2 100M ST/SC single-mode/multi-mode fiber transceivers for up to 30KM distance. The NetMaster configuration utility and USB port for configuration file can help mass installation and site support. DS306 supports latest ERPS v2 ring standard and is fully compatible with 3rd party devices for flexible network planning. Wide operation temperature design (-40°~70°C) can withstand critical industrial environment. All switches pass 4 hours 60°C stress test before delivery to ensure utmost quality.
