Product Description
IBM EN2X PCIe3 LP 4-port 10GbE BaseT RJ45 Adapter (CCIN 2F04, P/N 03JP016)
The IBM EN2X is the low-profile variant of the high-performance PCIe3 quad-port 10 Gigabit Ethernet network adapter, equipped with four RJ45 copper ports supporting 10GBASE-T. Designed for IBM Power Systems servers that utilize low-profile PCIe slots, this adapter enables high-bandwidth Ethernet connectivity over standard Category 6A / Category 7 twisted-pair cabling (up to 100 m reach), making it ideal for environments preferring copper infrastructure over fiber. It is optimized for virtualization, cloud workloads, and high-throughput networking 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 low-profile interface for high throughput and low latency in space-constrained servers
- 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), VLAN tagging, and jumbo frames
- Energy-efficient design with intelligent power management for copper-based 10GbE
- Low-profile form factor (includes low-profile bracket) compatible with PCIe3 slots requiring reduced height
- Reliable performance for dense 10GbE copper networking in Power Systems servers
