Description
The HP 133749-B21 is a specialized Network Interface Card (NIC) designed for environments that still utilize Token Ring networking technology. This PCI-based card allows compatible desktop computers and servers to connect to a Token Ring network, supporting both 16 Mbps and 4 Mbps data transfer rates. Token Ring was a popular networking standard in the past, known for its deterministic access method which prevented collisions, making it suitable for applications requiring predictable network performance. A key feature of this card is its Wake-On-LAN (WOL) capability. WOL allows the computer to be powered on or woken up from a low-power state by a network message. This is particularly useful in enterprise environments for remote management and maintenance, enabling IT administrators to power on machines for updates or troubleshooting without physical access. The card connects to the network via an RJ-45 connector, which is standard for Ethernet, but in this case, it is used for Token Ring signaling. Given the widespread adoption of Ethernet, Token Ring networks are now considered legacy technology. However, for organizations that maintain such infrastructure, the HP 133749-B21 provides essential connectivity. It requires a free PCI slot on the motherboard and compatible drivers for the operating system to function. This card is a piece of networking history, catering to specific niche requirements.
