G301 - Unmanaged 4-Port Rugged Industrial Ethernet Switch with PoE (Product Discontinued)

Unmanaged Industrial Ethernet Switch

The G301 is an unmanaged 3U Ethernet switch implemented as a CompactPCI Serial board. It occupies one peripheral slot, using a 4 HP front panel sporting 4 Gigabit Ethernet ports on RJ45 connectors. Options include M12 front connectors and a P6 connector for the rear I/O Ethernet signals from the board's fifth Gigabit Ethernet port.

Reliable Communication System Component

The G301 supports full-duplex and half-duplex operation with auto-negotiation and high-speed non-blocking store-and-forward switching. The switch is fault tolerant and restores itself on its own. Its built-in test mechanisms make the G301 an even more reliable component in the communication system.

In addition, the switch can act as Power over Ethernet (PoE) Power Sourcing Equipment (PSE), supplying other devices on all ports with up to 7W (class 1, 2) per port for power according to IEEE 802.3 Section 2 - Type 1, class 1 and 2 (formerly known as IEEE 802.3af). The maximum power available for one G301 is limited to 28 W, according to CPCI-S.0 specification.

Compliant to Railway Standards

The board is specifically designed for rugged mobile communication systems. It is thus for example fully compliant with the EN 50155 railway standard, screened for a -40°C to +85°C operation temperature and ready for coating.
