G303 - Unmanaged 16-Port Industrial Ethernet Switch

Unmanaged Industrial Ethernet Switch

The G303 is an unmanaged 3U Ethernet switch implemented as a CompactPCI Serial board. It occupies one peripheral slot, using a 4 HP front panel with 3 Gigabit Ethernet ports on RJ45 or M12 connectors. The G303 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 G303 supports full-duplex and half-duplex operation with auto-negotiation, high-speed non-blocking store-and-forward switching. Its built-in test mechanisms make the G303 an even more reliable component in the communication system. Using the EEPROM, the port speed and duplex can be configured, and the port-based VLAN-IDs can be assigned.

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 to +85°C operation temperature and ready for coating.
