Black Box Heavy-Duty Edge Switch Standard - switch - 6 ports

Metal-encased office network switches with dual fiber ports! 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 wall-mounted 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 daisy-chain 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 wall-mounted 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. Don't see it? Just ask.
