3Com 3C781 enterprise networking (SuperStack / CoreBuilder / LinkBuilder / OfficeConnect / Switch families) Switch / Carrier Ethernet Line Card

The 3Com 3C781 is a LinkBuilder FDDI Management Module, a genuine 3Com networking component from the LinkBuilder FDDI concentrator range. It provides management and monitoring functions for a LinkBuilder FDDI chassis, giving administrators visibility of ring status, port state and fault conditions across the fibre-based FDDI network it sits in. FDDI networking of this generation was widely deployed as a high-speed campus or backbone technology through the 1990s, ahead of the switched-Ethernet upgrades that followed, and installations built around this equipment sometimes remain in place for specialist or legacy applications. A genuine spare like this restores full monitoring capability after a module failure or lets an existing LinkBuilder FDDI chassis keep running at full capacity. Specifiers should confirm compatibility with their specific LinkBuilder FDDI chassis revision before ordering. Tech-Star is UK-based and ships worldwide.
