The HP NC4621 16/4 Token Ring PCI Express Network Interface Card (part number 166479-001) is a legacy network adapter designed for systems requiring Token Ring connectivity at 16 Mbps or 4 Mbps speeds. This PCI Express card provides dual-speed operation, supporting both 16 Mbps and 4 Mbps Token Ring networks for backward compatibility with older enterprise installations. The NC4621 is suitable for integration into HP servers and workstations running legacy Token Ring infrastructure, particularly in financial institutions, manufacturing facilities, and government environments where Token Ring networks remain operational. Typical applications include connecting systems to existing 802.5 Token Ring LANs where modernization timelines extend beyond current network technologies.
