Gigabit Ethernet Switch
As 1553 bandwidth in aircraft is consumed by multi function displays, moving maps, and multiple full rate video feeds, system integrators are looking for aircraft qualified, Gigabit Ethernet solutions which operate in severe environments without the need for forced air cooling.
The Aeronix Gigabit Ethernet Switch (GES) with its rugged, monolithic design is proven for use in harsh commercial, industrial, and military environments which enables system integrators to focus on what to do with all of the data instead of how to move it around.
The GES is a 12 port Gigabit Ethernet switch which has been designed specifically for integration into aircraft where weight, size, and power are all of the highest priority. At less than 3 pounds and with dimensions of 8.25” x 5.1” x 1.38”, the GES is very compact which allows it to fit into spaces previously unusable for rugged, gigabit class switches. With an average power consumption of 16 watts with all 12 ports active, the GES is very low power which allows for ambient air cooling. Meeting MIL-STD-704A power specifications and shock/vibration qualification to aircraft gun fire levels, the GES will operate through the worst that your application can dish out.
The small footprint of the GES is not at the cost of functionality. At the heart of the GES is a fully manageable switch fabric which includes support for VLAN’s, QoS, Link Aggregation, IPv6, and Ingress/Egress monitoring.
The GES contains an in-band ARM9 management processor which will allow custom management functions as required by the integrator. A serial port is also available in the form of an Ethernet to serial bridge which allows control of legacy equipment from anywhere in the network.

Capabilities
The GES is based on two eight port 10/100/1000 QoS Ethernet Switch ICs The following list is a sub-set of the capabilities of the Switch IC’s:
Egress tagging/untagging - selectable per port or by 802.1Q VLAN ID
Port Based VLANs - supported in any combination or 802.1 VLAN support for 4096 VIDs
Port States and BPDU handling for spanning tree
802.1X Source MAC address authentication
Quality of Service - switch architecture provides non-blocking switching in all traffic environments
Link Aggregation (802.3ad) - allows two or more links to be trunked to increase the total bandwidth and provide a fail safe if one of the links fails
A high speed, non-blocking, QoS switch fabric with support for four traffic classes based on:
- Port
- IEEE 802.1p
- IPv4’s TOS or Diff-Serv
- IPv6’s Traffic Class
- 802.1Q VID
- DA MAC address
- SA MAC Address
- Back-pressure flow control on half-duplex ports
- Pause-frame flow control on full-duplex ports
- Lookup engine supports 1024 MAC address entries with learning and aging
- Auto-MDI/MDIX and polarity correction
All of these features can be accessed thru the Aeronix GES Programming Fixture (P/N AE100937-001).
The Management Processor in the GES is an ARM9 running at 96 MHz. It is directly connected to a dedicated in-band Ethernet port on the Switch IC’s. It is capable of running a TCP/IP stack so that it can be an active participant on a network serviced by the GES.
Aeronix can create custom loads for this processor that will allow increased GES management functionality and/or customer defined custom applications that would be hosted on this processor. This processor, after startup, only services the Maintenance port, thus it is only lightly loaded.
