24x Gigabit ports 2x Gigabit SFP ports 52 Gbps switching capacity Hardened IP30 rated metal switch Includes DIN-Rail and wall mounts Extreme -40°, 75° C (-40°, 167° F) operating temperature range Redundant power inputs with overload current protection Alarm output triggered by power failure Power supply sold separately (models: TI-M6024, TI-S15052) Lifetime WarrantyTRENDnet's Industrial Gigabit DIN-Rail Switches feature a rugged IP30 rated metal enclosure and are designed to work in the harshest networking environments. This Industrial Unmanaged Switch is designed to withstand a high degree of vibration and shock, while operating in both high and low temperatures for industrial environments within -40°, 75° C (-40°, 167° F). Redundant power inputs with overload current protection on the industrial unmanaged switch minimizes network downtime. This hardened industrial switch features copper gigabit ports for high-speed device connections, and gigabit SFP ports for long distance fiber networking applications. Gigabit Ports This industrial switch features gigabit RJ-45 ports for high-speed device connections, and gigabit SFP ports that support long distance fiber networking applications. Redundant Power Multiple power inputs provide redundant power with overload current protection on this hardened industrial switch, minimizing overall network downtime (power supply sold separately).Industrial Hardened Design Equipped with a rugged IP30 rated housing, designed to withstand a high degree of vibration and shock, and operate within an extreme temperature range of -40°, 75° C (-40°, 167° F).
