TRENDnet's 10-Port Hardened Industrial Gigabit DIN-Rail Switch, model TI-G102, has eight dedicated gigabit ports, plus two gigabit RJ-45 / SFP shared ports. Users are able to connect eight devices to the switch, while still providing two gigabit ports for additional network connections. The switch is equipped with an IP30 rated metal enclosure, designed to withstand a high degree of vibration and shock, while operating within a wide temperature range of -40° - 75°C (-40° - 167°F) for industrial environments. Gigabit Speeds Ten gigabit ports provide high-speed network connections to devices, and a 20 Gbps switching capacity allows data traffic to flow smoothly, reducing traffic bottlenecks. Fault Tolerance Features dual redundant power inputs with output alarm relay.
