Aitech launches A661m military GbE switch
Aitech Defense Systems has launched the rugged A661 Layer 2/3 IPv6 48-port Gigabit Ethernet (GbE) switch for military applications, as announced by the company on 11 May.
The standalone GbE switch interconnects several subsystems to pass data across a rugged broadband network. It can be used in several military, aerospace and low-earth orbit space environments.
The radiation-tested and qualified A661 GbE switch is suitable for interconnecting weapons platforms to multiple independent data servers to form large, compute clusters and interfacing to data archive drives. The 2 x 24 GbE switch unit has two Series 400 conduction-cooled C660 24-port Ethernet switches encased in a cold plate-cooled enclosure.
The switch is EMI/RFI-protected and housed in a chassis designed to withstand severe shock and vibration as well as exposure to altitude, humidity and temperature extremes. It comes with its own operating system and Ethernet application, requiring no additional functions or user codes.
The A661 features a radiation-tolerant, integrated ARM Sheeva 800MHz processor and DDRII-320MHz memory controller. The switch also includes built-in test and board management devices, such as an elapsed time recorder, temperature sensors, and a system power controller.
A proprietary solid-state transition module from Aitech Defense Systems routes I/O signals between the backplane and the front panel connectors and an input power line filter reduces induced or radiated EMI/RFI noise. Military-grade MIL-STD-38999 connectors on the front panel provide system power and I/O connections.
