Unlike the Ethernet switches in your wiring closet or computer center, the Ethernet switches at the edges of your network have to put up with the bumps, the dirt, the dampness, and the temperature fluctuations that happen out in the real world. This is where our Extreme Heavy-Duty Edge Switches come in.

These tough, 6-port Ethernet switches enable you to expand your network even into harsh environments such as the outdoors. They're robust, they're easy to set up, and they're available with a vast array of interface and power options. In fact, they're everything you're looking for in an edge switch!

Can be used with Standard and Hardened models, too.
The switches featured here are the Extreme Heavy-Duty Edge Switches. But we also offer Standard and Hardened versions. All three types come in a sturdy steel case that withstands heavy use, and all work together seamlessly. You can use inexpensive Standard Switches in protected office environments, choose the more robust Hardened models for the factory floor, and use the Extreme Heavy-Duty Edge Switches in outdoor areas.

Built tough!
Extreme Heavy-Duty Edge Switches are ideal for outdoor applications such as traffic signal control, or for sensors or surveillance cameras in outdoor plants.

In addition, the switches are rated for above-the-ceiling plenum installation and rated for an extreme temperature range of -40 to +167° F (-40 to +75° C). They also feature a sealed case, which uses its own metal shell as a heat sink.

Multiple power options.
AC-powered Extreme Switches feature robust 100- to 240-VAC power supplies. DC-powered Extreme units have internal screw terminals for connecting DC power in addition to an AC power jack. Because these models have dual power connections, you can use them simultaneously with both your DC power supply and an AC power adapter (sold separately) to provide redundant power input.

Run the distance!
Multimode models support up to 2 kilometers (1.2 miles) between switches. For longer distances, choose single-mode models for up to 20 kilometers (12.4 miles) or single-mode, long-distance models for an incredible 40 kilometers (24.8 miles) between links.

You can daisy-chain Heavy-Duty Edge Switches together indefinitely, making them ideal for applications such as traffic signals where many switches are needed over a long distance.

Easy to set up.
Heavy-Duty Edge Switches are literally plug-and-play. All copper ports are autosensing for speed and duplex, adjusting to the connected device automatically. Plus, the UTP ports feature Auto MDI/MDI-X, eliminating the need for crossover cables.

Each switch has two full sets of LED indicators: one set on the front for viewing convenience when the switch is DIN rail or wall-mounted and one set mounted in the end next to the media ports for easy viewing when units are in a rackmount tray.

Heavy-Duty Edge Switches feature non-blocking switching architecture with a 2K MAC address table. The 128K buffer memory makes it easy to interconnect 10-Mbps and 100-Mbps devices.

• Two 100-Mbps fiber ports and 4 10-/100-Mbps RJ45 switch ports.


• Fiber interfaces are SM, SC, 20km range.


• Suitable for dusty or dirty environments with a temperature range between -40 and +167 F (-40 to +75 C).


• 24VDC power input.


• Includes panel mount kit.
