GP3 - 4-Port Gigabit Copper Ethernet Line Card with PoE

The GP3 is a 3U Gigabit Ethernet PHY line card, with optional PoE support, implemented as a CompactPCI Serial board. It occupies one peripheral slot using a 4 HP front panel with four Gigabit Ethernet ports on M12 X-coded connectors. Alternatively, the GP3 can be supplied with four RJ45 connectors on the front panel.

The GP3 is designed to work in combination with the G101 CompactPCI Serial managed industrial Ethernet switch.

The GP3 features four connectors on the front panel, which can be used to create 4 ports of copper Gigabit Ethernet. In addition, the card can act as Power over Ethernet (PoE) Power Sourcing Equipment (PSE), supplying other devices on all ports with power. Each interface supports a data transfer rate of 1 Gbit/s, and provides two LEDs to indicate the link and activity status.

The GP3 operates with a primary voltage supply of +12 V, which is provided via the rear CompactPCI serial connector. All additional required voltages are generated onboard. It is fully compliant with the EN 50155 railway standard, qualified for a -40 to +85°C operation temperature and ready for coating.
