The Aeronix Gigabit Ethernet Switch AB12 provides twelve Tri-speed Ethernet ports for use in commercial, industrial, and military applications that require ultra-high data transfer rates in a self-contained ruggedized package. The rugged design requires no forced air or conductive cooling, allowing operation in a broad range of harsh environments including operation in uninhabited aircraft bays.

The AB12 design is based on the widely-fielded Aeronix GES Gen2 product but adds a more powerful processor with more efficient quad PHY’s, enabling a lower maximum power consumption but with a more extensive Layer 2 management capability. Additional functions like STP prevent looping and provide more efficient communication using cheapest cost routes and route recovery in case of link failure.

Each of the twelve IEEE 802.3ab ports can individually auto-detect data rates of 10, 100, or 1000 BASE-T, or can be managed externally. The PHY’s in the AB12R offer extensive built in test utilizing Time Domain Reflectometry to detect problems in the platform wiring during Startup BIT.

The AB12 is a fully managed Layer 2 switch with the capability of customer specific configurations. The management functions are stored in non-volatile memory for fixed configurations, or loaded at startup for application specific requirements.
