IBM EN2W PCIe3 4-port 10GbE BaseT RJ45 Adapter (CCIN 2F04, P/N 03JP016)

The IBM EN2W is a high-performance PCIe3 quad-port 10 Gigabit Ethernet network adapter featuring four RJ45 copper ports with 10GBASE-T support. Designed for IBM Power Systems servers, this full-height adapter enables high-bandwidth Ethernet connectivity over standard Category 6A / Category 7 twisted-pair cabling (up to 100 m reach), eliminating the need for fiber transceivers in many environments. It is optimized for data center networking, virtualization, and high-throughput workloads in AIX, IBM i, Linux, and VIOS environments.

Features

Four RJ45 ports supporting 10 Gb/s, 1 Gb/s, and 100 Mb/s Ethernet (auto-negotiating)
PCIe 3.0 x8 interface for high throughput and low latency
Support for IEEE 802.3an 10GBASE-T, 802.3ab 1000BASE-T, and 802.3 100BASE-TX standards
Up to 100 meters reach over CAT-6A / CAT-7 copper cabling (shorter distances on CAT-6)
Advanced offload capabilities including TCP/UDP/IP checksum offload, large send offload, receive side scaling (RSS), and VLAN tagging
Jumbo frame support (up to 9,600 bytes) for improved efficiency
Short, full-height form factor with bracket for standard PCIe3 slots
Energy-efficient design with intelligent power management for copper-based 10GbE
