Bay Networks 5575F Token Ring Host Adapter 16/4 Mbps RJ-45
The Bay Networks 5575F is a 16/4 Mbps Token Ring host adapter designed for connection to IEEE 802.5 compliant token ring networks. This network interface card enables computers and workstations to join token ring LANs, which were widely deployed in corporate and industrial environments during the 1990s and early 2000s. The adapter provides dual-speed operation, supporting both 16 Mbps and 4 Mbps token ring topologies for backward compatibility with mixed-speed networks.

Applications
Token Ring networking was a primary LAN technology used throughout the 1980s, 1990s, and early 2000s, particularly in enterprise, financial, and industrial settings where its deterministic access and priority-handling capabilities were valued. The 5575F adapter enabled connection to these networks and was installed in servers, workstations, and computers requiring token ring connectivity. Token Ring eventually declined as Ethernet became the dominant networking standard, but legacy systems and air-gapped networks continue to use token ring infrastructure in select industries. This adapter is sought by collectors, legacy system maintenance technicians, and organizations maintaining token ring networks that require replacement or expansion cards.
