Product Features

  • Two 100-Mbps fiber ports and 4 10-/100-Mbps RJ45 switch ports.
  • Fiber interfaces are MM, ST, 2km range.
  • 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.

Details

  • Support VLAN tagging and spanning tree passthrough.
  • Include Link-Loss-Learn (LLL) feature for fast network recovery.

  • These easy-to-set-up Ethernet switches feature the same heavyweight metal case as our more robust Hardened and Extreme Heavy-Duty Edge Switches but are for use in clean, temperature-controlled environments, such as offices and wiring closets.

    Because all three types work together seamlessly, you can use these 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.

    All switches each have two full sets of LED indicators: one set on the front for viewing and one set mounted next to the media ports, so you get a clear view of the LEDs from any angle.

    Use Standard Heavy-Duty Edge Switches as standalone or wallmounted units. You can also rackmount up to eight units in the optional Rackmount Tray.

    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 daisychain Heavy-Duty Edge Switches together indefinitely, making them ideal for applications where many switches are needed over a long distance.

    Plug-and-play.
    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 wallmounted and one set mounted in the end next to the media ports for easy viewing when units are in a rackmount tray.

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

    Fast, redundant backup.
    Heavy-Duty Edge Switches feature Link-Loss-Learn (LLL) for fast network recovery when using the switches in a redundant application. In a normal network situation where you have a primary link and a backup link, the network can take as much as a few minutes to recover after the primary link goes down. This is because, when the link breaks, the switch will use its old MAC address table to try to send data to the disabled port.

    However, if a link breaks with LLL in place, the switch senses the disconnect and instantly clears its MAC address table, forcing a new address table that includes the new link.

    LLL works on both fiber and copper ports, and you can enable or disable this feature as needed.
