This circuit board is intended for installation inside compatible LANplex chassis, where it facilitates FDDI traffic handling within the hub’s switching fabric for legacy networks. Identified by part number 322-00704-000 and carrying Revision 4, this module is commonly referenced in refurbishing catalogs and service listings as the replacement FDDI switching circuit board for LANplex models such as the 2500 and 6000 families. Built to support Fiber Distributed Data Interface networking, the board serves as an internal component rather than a standalone switch, enabling legacy FDDI segments connected to the hub to communicate across the fiber ring. Buyers typically source this item from secondary markets for restoration or maintenance of vintage 3Com LANplex infrastructure. As a vintage hardware part, it is essential to ensure compatibility with the specific LANplex chassis and to handle the board with standard electrostatic precautions and legacy 3Com hardware guidelines. \u003c\/p\u003e\u003c\/div\u003e","brand":"3COM","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51656667889966,"sku":null,"price":548.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d0756236-6ee7-4089-afa6-82ea22bcaebe.jpg?v=1769462565","url":"https:\/\/plgautomation.com\/products\/3com-322-00704-000-fddi-switching-module-circuit-board","provider":"PLG Automation ","version":"1.0","type":"link"}
