Gigabit Ethernet Switches for Rail Vehicles

Designed to support video, LCDs and wireless LAN access points, the devices are part of the company's IP Train network infrastructure for the creation of intelligent trains. The Viper-112-T3G has three Gigabit Ethernet ports and nine standard Ethernet ports. The Viper 212-T3G provides the same port configuration, but with additional routing capability to enable the connection of subnets and improve overall network performance. The Viper-112-T3-P8 offers three Gigabit ports, a single standard Ethernet port and eight Power-over-Ethernet ports that support the IEEE 802.3at plug-and-play PoE communications standard. PoE enables both power and data to be transmitted on a single multi-core cable, especially useful for camera applications, reducing overall wiring and enabling faster installation. The Viper 212-T3G-P8 provides the same port configuration, but extends the functionality by offering routing capability. The Viper PoE switches deliver up to 66 W of power across their eight PoE ports and are able to isolate the input DC voltage from the connected devices, to protect them from power surges. Power distribution is managed, with ports tuned to maximize distribution efficiency.
