ORing’s managed Ethernet switches are designed for industrial applications, such as rolling stock, vehicle, and railway applications. IGPS-9842GTP is managedredundant ring PoE Ethernet switch with 8x10/100/1000Base-T(X) P.S.E. ports and 4x10/100/1000Base-T(X) copper ports and 2x100/1000Base-X SFP ports which is compliant with EN50155 request. With completely support of Ethernet Redundancy protocol, O-Ring (recovery time < 30ms over 250 units of connection) Open-Ring, O-Chain, *note MRP and MSTP (RSTP/STP compatible) can protect your mission-critical applications from network interruptions or temporary malfunctions with its fast recovery technology. IGPS-9842GTP also support Power over Ethernet, a system to transmit electrical power up to 30 watts (total 120watts max.), along with data, to remote devices over standard twisted-pair cable in an Ethernet network. Each IGPS-9842GTP switch has 8x10/100/1000Base-T(X) P.S.E. (Power Sourcing Equipment) ports. P.S.E. is a device (switch or hub for instance) that will provide power in a PoE connection. And support wide operating temperature from -40 to 75°C. IGPS-9842GTP can also be managed centralized and convenient by Open-Vision, Except the Web-based interface, Telnet and console (CLI) configuration. Therefore, the switch is one of the most reliable choices for rolling stock and highly-managed Ethernet application.
