ESCRIPTION
The DuraNET 20-11 is a rugged Commercial Off the Shelf (COTS) Gigabit Ethernet switch subsystem
optimized for Size, Weight, Power and Cost (SwaP-C) sensitive embedded military and civilian computer
network systems applications
Featuring advanced Layer 2+ networking features with 8 ports of non-blocking wire-speed
10/100/1000Mbps connectivity, an integrated management processor, and extremely low power
consumption, the DuraNET 20-11 enables reliable local area network (LAN) switching across extended
operating temperature ranges (-40 to +85C) and extreme shock/vibration conditions for technology
refresh and new platforms, including mobile, tactical, aerospace, and ground vehicle applications
Featuring micro-miniature MIL-DTL-38999 like connectors in a sealed IP67 (dust/water proof) aluminum
chassis, the unit serves as an ideal solution for connecting a large number of IP-enabled embedded
devices, including computers, cameras, sensors, and command-and-control equipment deployed in digital
networked architectures of manned and unmanned system platforms at the network edge. To enhance
reliability, the unit features no moving parts, a near cable-less internal design, industrial temperature
grade components, EMI filtering, and a MIL-STD- 1275/704 power supply that protects against
vehicle/aircraft voltage surges, spikes and transients. The unit is qualification tested to extreme MIL-STD-
461F, RTCA/DO-160G, MIL-STD-810G thermal, shock, vibe, humidity, altitude, ingress, and EMI/EMC
conditions
This fully managed, Layer 2 Gigabit switch provides a powerful set of carrier-grade networking features,
including support for IPv4 and IPv6 multicast traffic, Virtual Local Area Networks (VLANs), port control
(speed / mode / statistics, flow control), Quality of Service (QoS) traffic prioritization, Link Aggregation
(802.3ad), SNMPv1/v2/v3 management, secure authentication (802.1X, ACLs, Web/CLI), redundancy
(RSTP/MSTP), precision timing (IEEE-1588v2), port monitoring, IGMP Snooping, Built in Test (BIT), and
data zeroization. The unit also supports Layer 3 IPv4 unicast static routing for IP routing to attached WAN
/ radio ports.
