Product Features

  • Four 10-/100-Mbps RJ45 switch ports.
  • Suitable for dusty or dirty environments with a temperature range between 32 and +104º F (0 to +40º C).
  • 100-240VAC power input.
  • Includes panel mount kit.


  • Part of the BLACK BOX® Media Converter Switch family, providing network extension for any environment.
  • Rackmount up to 16 units in the optional Rackmount Tray or Powered Rackmount Tray.
  • Mount on DIN rails with optional brackets.
  • Two sets of LEDs enable you to see status information from the front, top, or side.
  • Support both half- and full-duplex operation.
  • Support VLAN tagging and spanning tree passthrough.
  • Available with many choices of AC and DC power supplies.
  • All ports support autonegotiation, so you can easily attach any 10- or 100-Mbps device.

  • Convenient Switches are versatile autosensing four-port switches that enable you to quickly add ports anywhere on your Ethernet network. They’re designed as part of our Media Converter Switch family and are available in the same robust chassis choices to fit environments ranging from comfortable offices to demanding outdoor installations. You can also choose from a wide range of power supplies and mounting options.

    Although Convenient Switches were designed to match our Media Converter Switches, you can also use them just like any other 10-/100-Mbps Ethernet switch to add ports anywhere on your network or even to build a small freestanding network.

    Adapt to nearly any environment.
    Convenient Switches come in three versions to adapt to nearly any environment. Because all three types work together seamlessly and also work with our family of Media Converter Switches, you can use inexpensive switches in the protection of the wiring closet and choose the more robust Hardened or Extreme Convenient Switches for harsh locations at your network's edge.

    Standard—These are our basic Convenient Switches for use in clean, temperature-controlled environments such as offices and wiring closets. Even though these models are designed for use in controlled environments, you’ll find that they feature the same heavyweight metal case as our more robust models.

    Hardened—These Convenient Switches are for dusty or dirty environments with temperatures that range between -13 and +140º F (-25 to +60º C). They use the metal case as a heat sink so no internal airflow is needed for cooling. The case is sealed to resist environmental contaminants such as dust, dirt, moisture, smoke, and insects. They're an ideal choice for demanding industrial applications such as factory floors.

    Extreme—Choose these robust units for outdoor use in exposed locations with temperature ranges of -40 to +167º F (-40 to +75– C)—all they need in the way of protection is shelter from direct rainfall. Like our hardened models, Extreme Convenient Switches feature a sealed case, which uses its own metal shell as a heat sink. Choose them for applications such as traffic signal control or for sensors or surveillance cameras in outdoor plants. Extreme Convenient Switches are rated for above-the-ceiling plenum installation.

    The features you're looking for.
    Convenient Switches are literally plug-and-play. All four UTP ports are autosensing for speed and duplex, adjusting to the connected device automatically. Plus, all ports feature Auto MDI/MDIX, eliminating the need for crossover cables.

    Each switch features nonblocking switching architecture with a 2K MAC address table. The 128K buffer memory makes it easy to interconnect 10-Mbps and 100-Mbps devices.

    The switches each have two full sets of LED indicators: one set on the front for viewing convenience when the Switch is DIN rail or wallmounted, and one set mounted in the end next to the media ports for easy viewing when units are in a rackmount tray.

    Choose from AC and DC power.
    Like our Media Converter Switches, Convenient Switches have the power options to support harsh environments. Standard models are available with AC power adapters only, in a choice of 115 or 240 VAC. Hardened Convenient Switches with AC power supplies feature 100–240-VAC power supplies built to the same tough standards. Extreme Convenient Switches with AC power supplies feature still more robust power supplies with a 100–240-VAC range.

    The power supplies with recessed IEC power connectors work with any IEC standard power cord, making them adaptable to most international locations.

    DC-powered Hardened and 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.

    Mounting options galore.
    Convenient Switches fit in where you need them. The switches come with neat, removable rubber feet so you can use them as standalone units. Or you can easily panelmount them with the included brackets and screws.

    For use with DIN rails, order the optional DIN Rail Mounting Bracket. This handy bracket features springmounting, enabling you to easily pop your Convenient Switches on and off the DIN rail without using a screwdriver or tightening set screws. DIN-rail-ready Media Converter Switches are also available—for details, contact our FREE Tech Support.

    For rackmounting in a central location, choose the optional Rackmount Tray or Powered Rackmount Tray. The powered tray provides power for up to eight units.
