3U CompactPCI serial-based Gigabit Ethernet switches from MEN Micro provide for high data processing and versatile I/O implementations. Each switch contains up to 16 Gigabit Ethernet ports on the back or three ports on the front panel and 13 on the rear. Both the managed G302 and the unmanaged G303 switches support full or half duplex operation, fast non-blocking store-and-forward switching and auto-negotiation as well as Layer 2 switching. Compliant to EN 50155 for railway operation, the switches are suitable for use in rugged applications. Operating temperature is -40°C to +85°C with shock and vibration tested in accordance with EN 61373. In a peripheral slot, the switches can take over typical tasks for connecting external devices without software. When used in the system slot, these full-mesh switches foster powerful multi-computer architectures, where CPU cards are plugged into the peripheral slots. Pricing for the managed G302 Ethernet switch starts at $810 and the unmanaged G303 starts at $538.
