描述

2352901-1 is a managed Gigabit Redundant Ring Ethernet switch featuring 8x10/100/1000Base-T(X) P.S.E. ports and 4x10/1000Base-T(X) ports, designed for EN50155 compliant industrial applications such as rolling stock, vehicle, and railway environments. The switch utilizes M12 connectors with 8-pin Female A-coding for robust connections and supports Ethernet Redundancy protocol with recovery time less than 30ms over 250 units of connection, along with MSTP (RSTP/STP compatible). It provides 90 Watts total PoE output power with 25 Watts typical power consumption (excluding P.S.E.), dual DC inputs (12-36VDC), and features overload current protection and reverse polarity protection. The switch operates in temperatures from -40 to 75°C and supports IEEE 802.3at PoE specification, 24 Gbps switching bandwidth, and 8K MAC table. Common applications include mission-critical railway and industrial environments where network reliability and fast recovery from interruptions are essential.
