G302 - Managed 16-Port Rugged Industrial Ethernet Switch (Product Discontinued)

Managed Industrial Ethernet Switch

The G302 is a managed 3U Ethernet switch implemented as a CompactPCI Serial board. It occupies one system slot or one peripheral slot, using a 4 HP front panel with 3 Gigabit Ethernet ports on RJ45 or M12 connectors and one service interface via M12. The G302 either features three Ethernet ports on the front and up to 13 Ethernet ports on the rear or alternatively all 16 Ethernet ports on the rear, which is the ideal solution for conduction cooling.

Reliable Communication System Component

The G302 supports full-duplex and half-duplex operation with auto-negotiation, high-speed non-blocking store-and-forward switching, Quality of Service (QoS) support with four traffic classes IEEE 802.1p and three-level 802.1x security. The switch is fault tolerant and restores itself on its own: If a link is temporarily unavailable, frames can be sent via backup/redundant links (spanning tree protocol/link aggregation) and no data loss occurs. Its built-in test mechanisms make the G302 an even more reliable component in the communication system.

Compliant to Railway Standards

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