Avionics Gigabit Ethernet Switches

The Aeronix Gigabit Ethernet Switch (GES) GEN2 with its rugged, monolithic design is proven for use in harsh military, commercial, and industrial environments. The GEN2 is a 12-Port Gigabit Ethernet switch designed for integration into aircraft where size, weight, and power are all of the highest priority.  With dimensions of 8.25” x 5.1” x 1.38”, weighing in at only 2 lbs, 12 oz, the GEN2 is very compact which allows it to fit into spaces previously unusable for rugged, gigabit class switches.  On average, the switch consumes only 16 watts at 28 VDC with all 12 ports active at Gigabit speeds.The GEN2 has undergone extensive qualifications for use in both manned and unmanned locations within multiple military aircraft.  The qualification standards include MIL-STD-704, MIL-STD-810, and MIL-STD-461.  At a TRL-9 and ~1000 installed units, the GEN2 is a mature product with proven reliability with plans to remain in production beyond 2025.

The GES Gen2 is a lightly managed layer 2 switch with some capability of customer specific configurations. The management functions, which run on an ARM processor, are stored in non-volatile memory for fixed configurations, or loaded at startup for application specific requirements. The Gen2 utilizes a small footprint OS which is advantageous for security conscious applications. No Ethernet data is stored in onboard processor RAM. The GEN2 Built In Test (BIT) capabilities are extensive and cover not only its internal functionality, but also uses Time Domain Reflectometry (TDR) to verify the integrity of connections to all other equipment.  For more product information and to download a GEN2 datasheet, click here


New Common Form Factor/Pin for Pin Compatible Products:

The GES AB12 switch utilizes the same switching fabric as the GEN2 with the added processing power of a Freescale processor and software necessary to support layer 2 infrastructure and management.  The AB12 maintains the same mounting footprint and is pin for pin compatible with the GEN2 yet consumes less power while providing additional functionality. This includes an In Band Secure Shell (SSH), HTTPS GU, SNMP V2/3 MIBs, Quality of Service, Port States, & BPDU handling for Spanning Tree Protocol,  Dynamic Host Configuration  client, and IGMP Snooping.

The GES AB12R upgrades to a more powerful switching fabric to support layer 3 functions with minimal impact on overall power consumption. The AB12R maintains the same mounting footprint and is pin for pin compatible with the GEN2 and AB12. It expands on the AB12 functionality by adding Link Aggregation, Layer 2 Tunneling,Stateful Firewall, Intrusion Detection Prevention, Network Address Translation, IPSEC, OSPF, RIP, and IPv6 IP Routing.
