NIU2A-ES2

Nano Interface Unit / Rugged Ethernet Switch - NIU

The NIU2A-ES2 is a small, rugged, low-power, self-contained Rugged Ethernet Switch system. It is powered by an integrated MIL-STD-704A (designed to meet) power supply. It is a Layer 3, fully managed switch providing sixteen (16) 10/100/1000Base-T (GbE) Ethernet ports and four (4) optional 10 Gb 850 nm fiber-optic ports. Additionally, there is one GbE and one RS-232 port for maintenance / configuration interface. The NIU-ES2 supports Open Systems Interconnection (OSI) model data link (L2) and network (L3) layer, quality of service (QoS) and security features. Ideally suited for rugged Mil-Aero applications, the NIU2A delivers off-the-shelf solutions that accelerate deployment of SWaP-optimized systems in air, land and sea applications.

The NIU2A-ES2 rugged switch provides scalable Ethernet links enabling networks including on-board vehicle, marine and aircraft platforms to field and expand digital network architectures for network-centric operations. The NIU2A-ES2 fits seamlessly in NAI’s Configurable Open Systems Architecture™ (COSA®) providing the most modular, agile and rugged COTS portfolio of embedded smart modules, I/O boards, Single Board Computers, Power Supplies and Ruggedized Systems.
