Keep critical systems on the wire with a dual-port Gigabit Ethernet adapter designed for IBM-compatible environments. This AddOn model mirrors the 90Y9370 form factor and gives server teams a practical way to add or restore network connectivity through a PCIe x4 interface. Dual open RJ-45 ports support 10/100/1,000 Mbps operation, making it suitable for standard access, management, and workload traffic where stable copper connectivity matters. For procurement teams, the value is in fit and function. This adapter targets deployments that need a compatible replacement or a cost-conscious expansion option without changing the server architecture. The dual-port design helps preserve flexibility for redundancy, segmentation, or separate traffic paths, while the PCIe x4 host interface keeps installation straightforward in supported systems. When uptime depends on predictable network access, a purpose-built adapter is often the right choice over generic alternatives. This model is aimed at environments that need dependable Ethernet connectivity, clean integration, and a familiar RJ-45 copper connection point for existing switching infrastructure.
