3Com 3C359 Token Ring 16Mbps PCI network adapter (part number 3C359) provides legacy token ring connectivity for enterprise systems requiring 16Mbps throughput over RJ-45 and DB-9 interfaces. The Tokenlink Velocity card fits standard PCI slots in desktop and server platforms, supporting deterministic token ring topologies common in manufacturing, finance, and industrial automation environments where predictable latency and collision-free transmission remain critical. Compatible with systems running NetWare, Windows NT, OS/2, and Unix-based token ring stacks. Typical applications include integration with existing token ring MAUs, wiring closets, and mainframe connectivity where legacy network infrastructure remains in production. Assembly required for installation; eco-friendly design. Refurbished unit tested and guaranteed; available via quote.
