Description
The IBM 23L4288 is a PCI-based network adapter, specifically an Input/Output Adapter (IOA), engineered to provide connectivity to Token Ring networks at a speed of 100 Megabits per second (Mbps). In its era, Token Ring was a prevalent local area networking technology, particularly in enterprise environments, known for its deterministic access method which ensured fair access to the network medium for all connected devices. This adapter utilizes the Peripheral Component Interconnect (PCI) bus, a standard interface for connecting hardware components to a computer's motherboard. The 100 Mbps speed indicates its capability for relatively high-speed data transfer within the context of Token Ring technology. The 'IOA' designation signifies its role as a crucial component for enabling input and output operations related to network communication within compatible IBM systems. The IBM 23L4288 would have been used in IBM servers or workstations that required integration into an existing Token Ring network infrastructure. Its function is to translate data between the computer's internal bus and the Token Ring network protocol, allowing for communication with other devices on the network. This adapter is a legacy component, relevant for maintaining or understanding older IBM network environments.
