The DuraNET® 1268 is a rugged Layer 2+ Gigabit Ethernet switch subsystem equipped with ten (10) triple-speed 10/100/1000Mbps ports for connecting IPv4 and IPv6 compatible computing devices onboard demanding network-centric (un)manned vehicle and aircraft platforms.
Protocols Support
This stand-alone unit features an onboard microprocessor for local/remote control and monitoring, as well as support for Quality of Service (QoS) traffic prioritization, Virtual Local-Area Network (VLAN) trunking, and Rapid Spanning Tree (RSP) redundancy.
To enhance security and system management, the unit integrates recoverable data zeroization capabilities for declassifying switch data, along with RS-232 Command Line Interface (CLI) and Ethernet management ports.
Status LEDs indicate zeroization signal, power, and port link/speed/activity.
Ruggedization
Small and lightweight in form factor, yet robust in mechanical design, the DuraNET 1268 switch serves as an ideal Commercial-Off-the-Shelf (COTS) solution to enhance situational awareness in Size, Weight, and Power (SWaP)-constrained aircraft, tactical ground vehicles and maritime assets. Integrating a conduction-cooled, aluminum chassis with sealed MIL-38999 connectors and isolated MIL-STD-1275/704 ower supply, this fully immersible subsystem is designed for harsh
MIL-STD-461E EMI/EMC and MIL-STD-810F thermal, shock, vibe, humidity, altitude, and ingress conditions. The system features all industrial temperature grade components, near cable-less design, and no moving parts for maximum MTBF reliability.
Four hardened Gigabit fiber optic ports can be optionally brought out through the rear panel of
the unit.
