Unmanaged Industrial Ethernet Switch
The G304 is an unmanaged 3U Ethernet switch implemented as a CompactPCI Serial board. It occupies one peripheral slot, using a 4 HP front panel with 4 Gigabit Ethernet ports on RJ45 or X-coded M12 connectors, and one direct Ethernet connection to the CPU card using PCI Express on P1. A P6 connector can optionally extend the number of Ethernet channels available on the board to six.
Reliable Communication System Component
The G304 supports full-duplex and half-duplex operation with auto-negotiation, high-speed nonblocking store-and-forward switching. Its built-in test mechanisms make the G304 an even more reliable component in the communication system.
In addition, the switch can act as Power over Ethernet Plus (PoE+) Power Sourcing Equipment (PSE), supplying other devices on all ports with up to 30 W (class 0, 1, 2, 3, 4) per port for power according to IEEE 802.3 Section 2 - Type 1 and 2 (formerly known as IEEE 802.3at). The maximum power available for one G304 is limited to 61.6 W, according to CPCI-S.0 specification.
Compliant to Railway Standards
The board is specifically designed for rugged mobile communication systems. It is, for example, compliant with the EN 50155 railway standard, supports a -40 °C to +85 °C operating temperature and rail-ready versions are coated.
