Product Features

  • Protect your Ethernet devices from extremes of heat, light, and cold—even dirt.
  • Operates in conditions of uncontrolled heat or cold—even outdoors.
  • Rugged, 18-gauge steel case seals out insects, dirt, smoke, and other contaminants.
  • The steel case also operates as a heat sink, drawing heat away from internal components.
  • Details

  • Plug-and-play, software transparent.
  • Daisychain the switch for a fiber optic Ethernet network hundreds of kilometers long!
  • Has two fiber ports.
  • Six 10-/100-Mbps RJ-45 ports provide half- or full-duplex operation.
  • Can be installed in NEMA 4 metal enclosures for all-weather outdoor use.
  • Also available with one multimode SC port and one single-mode SC port.


  • Networking isn't always done in climate-controlled offices. Sometimes your Ethernet network is an outright inhospitable environment where the temperature extremes wreak havoc with your office devices' circuitry. That's why you need the industrial-strength Black Box® Hardened Ethernet Switch.

    The switch is designed to operate in applications where the temperature cannot be controlled, from the withering heat of the desert sun to the numbing cold of arctic conditions.

    The case is made of steel.
    The rugged, 18-gauge steel case is engineered to function as a heat sink, which draws the heat away from the internal electronics and dissipates it. To minimize the heat dissipation problem further, each switch uses only 15 watts of power.

    Built tough, the Hardened Ethernet Switch is virtually impenetrable. Problems such as convection air, insects, dirt, and dust can't enter it. And if the switch happens to be adjacent to a building fire or a plenum fire, the case will not allow smoke inside to damage the electronics. For complete invulnerability to the elements, the switch can be installed in watertight NEMA 4 metal enclosures for all-weather outdoor operation.

    Applications for the Hardened Ethernet Switch include roadside traffic data collection and control stations, industrial plant locations, plenums and ceilings in commercial buildings, and military tents and field sites.

    Mix two parts Ethernet with two parts media…
    The Hardened Ethernet Switch is available with autoranging power supplies.

    The switch features six autonegotiating RJ-45 ports for 10-/100-Mbps applications. These ports operate in either half- or full-duplex mode.

    In addition to the RJ-45 port, the Hardened Ethernet Switch is equipped with two ports for full-duplex, 100-Mbps fiber optic connectivity.

    This model has two multimode SC ports. Daisychain the switch in "string" applications and create an Ethernet network hundreds of kilometers long! Configurations with more than 10 units in a string have been tested with normal data traffic.
