IBM 34L0501 High Speed 100Mbit/s RJ-45 100/16/4 Token Ring PCI Express Network Adapter

Product Description

The IBM 34L0501 is a specialized network adapter designed to bring Token Ring networking capabilities to modern computer systems equipped with a PCI Express (PCIe) slot. Token Ring was a popular local area networking technology, particularly in enterprise environments, known for its deterministic access method which prevented data collisions. This adapter supports multiple data rates, including high-speed 100 Mbit/s, as well as the legacy 16 Mbit/s and 4 Mbit/s speeds, ensuring compatibility with various Token Ring network infrastructures. The adapter features an RJ-45 connector, which is the standard physical interface for Ethernet networks, but in this context, it is used for connecting to Token Ring cabling systems (often using specific baluns or adapters depending on the cable type). The use of the PCI Express interface signifies that this adapter is intended for installation in newer motherboards, offering higher bandwidth and lower latency compared to older PCI or ISA bus adapters. This allows for efficient data transfer between the computer and the Token Ring network. This specific part number, 34L0501, identifies an IBM-branded component, indicating its origin and likely quality standards associated with IBM's networking hardware. It is a crucial component for organizations that still maintain or require connectivity to legacy Token Ring networks, bridging the gap between older infrastructure and contemporary computing platforms. Its functionality is essential for systems that need to participate in or communicate with devices on such networks.
