FeaTures
The Ethernet switches in your wiring closet or computer center 
enjoy a protected environment. 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 
Heavy-Duty Edge Switches
 from Black Box come in.
Heavy-Duty Edge Switches
 are tough, 6-port Ethernet switches 
that enable you to expand your network into harsh environments such 
as factory floors or the outdoors. They’re robust, easy to set up, and 
available with a vast array of interface, power, and durability options. 
In short, they’re everything you’re looking for in an edge switch.
Built tough
All 
Heavy-Duty Edge Switches
 come in a sturdy steel case  
that withstands heavy use.
The switches come in three versions to adapt to nearly any 
environment. Because all three types work together seamlessly,  
you can use inexpensive Standard 
Heavy-Duty Edge Switches
 in 
protected office environments and choose the more robust Hardened 
or Extreme 
Heavy-Duty Edge Switches
 for harsh locations at your 
network’s edge.
Standard Edge Switches
•  For use in clean, temperature-controlled environments  
such as offices and wiring closets.
•  Feature the same heavyweight metal case as our more robust
models.
Hardened Edge Switches
•  For use in dusty or dirty environments—ideal for demanding
industrial applications.
OVERVIEW
•  Rated for a temperature range between -13 and +140°F  
(-25 and +60°C).
•  The metal case acts as a heat sink so no internal airflow  
is needed for cooling.
•  Sealed case resists contaminants such as dust, dirt, moisture,
smoke, and insects.
Extreme Edge Switches
•  Robust units for outdoor use require protection only from direct
rainfall or standing water.
•  Ideal for applications such as traffic-signal control, or for sensors  
or surveillance cameras in outdoor plants.
•  Rated for above-the-ceiling plenum installation.
•  Rated for extreme temperature ranges of -40 to +167°F  
(-40 to +75°C).
•  Features a sealed case, which uses its own metal shell  
as a heat sink.
Multiple power options
•  Standard models come with AC power adapters only,  
in a choice of 115 or 240 VAC.
•  AC-powered Hardened and Extreme Switches feature robust  
100- to 240-VAC power supplies.
•  DC-powered Hardened and Extreme units have internal screw
terminals for connec ting 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.
Daisychain switches for easy network extension.
