Product Description
The 3Com 3C359 is a network adapter card specifically designed for Token Ring networks, a legacy networking technology that was popular in enterprise environments before being largely superseded by Ethernet. This card supports a data transfer rate of 16 Mbps, which was a common speed for Token Ring networks, offering deterministic access to the network medium. The adapter utilizes the PCI (Peripheral Component Interconnect) bus interface, allowing it to be installed in compatible slots on modern computer systems, although Token Ring itself is now considered an obsolete technology. The card features an RJ-45 connector, which was used for connecting to Token Ring cabling systems, often referred to as 'Type 1' or 'Type 2' cabling, though RJ-45 was also used in some Token Ring implementations. Additionally, it includes a DB-9 connector. This secondary connector might have been used for various purposes, such as connecting to a network management console, providing a serial port for diagnostics, or potentially for alternative cabling configurations depending on the specific Token Ring topology being implemented. Token Ring networks were known for their reliability and predictable performance due to their token-passing access method, which avoided collisions unlike early Ethernet. While Ethernet has become the dominant networking standard, the 3C359 represents a piece of networking history, catering to organizations that maintained Token Ring infrastructure. Its inclusion of both PCI and specific Token Ring connectors highlights the transition period in networking hardware.
