Ethernet Switches: ToughSwitch 3

• Meets MIL-STD environmental and electromagnetic requirements
• Nine real-time, auto detecting 10/100BaseT Ethernet ports
• Ideally suited for use in military vehicles
• Meets MIL-STD power requirements for military vehicles
• Meets MIL-STD requirements steam and waterjet cleaning

The ToughSwitch 3 is a dedicated, ruggedized Ethernet switch designed to meet MIL-STD environmental and electromagnetic requirements. It operates from 24 VDC vehicle power in accordance with MIL-STD-1275B, making it ideally suited for use in military vehicles.

Rugged, MIL-STD design

The ToughSwitch 3 is painted with Chemical Agent Resistant Coating (CARC) paint, meaning it will resist the effects of biological and chemical decontamination agents, including DS2 and STB, applied to external surfaces and components using standard decontamination procedures and methods. It also meets MIL-STD-108 requirements for steam and waterjet cleaning.

The ToughSwitch 3 is outfitted with two MIL-STD connectors, one for power and a second for Ethernet connectivity. Since all the ports are auto-MDI/MDIX, any port can be connected to another Ethernet switch as an uplink.

High performance switching

The ToughSwitch 3 is designed to minimize collisions and network loading. Unlike an Ethernet hub that broadcasts all messages out all ports, it automatically determines and remembers where an Ethernet device is located and routes messages only through the appropriate port. It also buffers messages and transmits them in a rapid-fire sequence using a real-time “store and forward” switching technique.The ToughSwitch 3 includes nine dedicated 10/100BaseT ports, any one of which can be used as an uplink port for network expansion. Each of these ports will independently sense the speed, allowing interfacing to both standard and fast Ethernet devices.
