Ethernet Lan/Wan

Ethernet LAN/WAN

Enhance your IBM Power Systems and AS/400 setups with our selection of reliable Ethernet LAN/WAN adapters. These PCI and PCIe-based IOAs provide essential network connectivity, supporting speeds from standard Ethernet to 10Gbps Gigabit and beyond. Options include single-port, dual-port, and quad-port configurations for copper (RJ45/UTP) or fiber (LC Duplex), with compatibility across legacy iSeries, AS/400, and various Power Systems generations (Power 5 through Power 11 where applicable). Adapters deliver full-duplex performance, IEEE 802.3 compliance, and features like multi-protocol WAN support or high-speed LAN attachment.

Compatibility Information

These IBM Ethernet LAN/WAN adapters are compatible with a wide range of IBM Power Systems (including Power 5, 6, 7, 8, 9, 10, 11) and legacy AS/400/iSeries models. Many are PCI/PCIe IOAs designed for direct attachment to Ethernet TCP/IP LANs, Token-Ring networks, or WAN/multi-protocol communications. They support full-duplex operations, IEEE standards, and features like Operations Console over LAN where applicable. Adapters suit internal installation in system units or I/O drawers, providing versatile networking for enterprise environments running IBM i, AIX, or Linux.
