Rugged Managed Ethernet Switch

April 19, 2019
NAI's ethernet switch supports Open Systems Interconnection model data link Layer 2 and network Layer 3.

A small, rugged, managed Ethernet Switch, NIU2A-ES2, is a Layer 3, fully managed switch providing 16 10/100/1000Base-T (GbE) Ethernet ports and 4 optional 10 Gbe 850 nm multimode fiber-optic ports. Additionally, there is one GbE and one RS-232 port for maintenance/configuration interface. The NIU2A-ES2 supports Open Systems Interconnection (OSI) model data link Layer 2 and network Layer 3, quality of service (QoS) and security features. It also integrates industry-standard Broadcom switch technology and the power of an NXP QorIQ processor hosting unparalleled quality of service, L3 management, and security services. 


The NIU2A-ES2 rugged switch provides scalable Ethernet links enabling networks including onboard vehicle, marine and aircraft platforms to field and expand digital network architectures for network-centric operations. With an extremely small footprint of 7.0 x 3.0 x 2.5 in. (including connectors), low-power requirements and a weight of approximately 2.75 lb., the NIU2A is ideally suited for rugged Mil-Aero and other SWaP-optimized systems in air, land and sea applications. It is designed to meet the requirements of MIL-STD-810G, MIL-STD-461F, and MIL-STD-704A. Conduction-cooled and convection-cooled models are available to suit most installation requirements.
