Lenovo Hinkserver X550-T2 Pcie 10Gb 2 Port Base-T Ethernet Adapter

The Lenovo 4XC0G88856 is a network interface card that brings two 10 Gigabit Ethernet connections to a compatible PCI Express slot. By delivering high-speed throughput over familiar RJ45 ports, it lets you upgrade bandwidth without moving to fiber.

Built on the Intel X550 controller, the adapter keeps latency low and packet processing efficient, which is important when virtual machines, storage traffic, or database workloads share the same server. Because it relies on standard CAT6a or CAT7 copper cabling, you can slot it into an existing rack or desktop setup without rewiring.

This card fits naturally in small business servers that need faster backup windows, in virtualization hosts looking to reduce network bottlenecks, and in lab environments where engineers test bandwidth-intensive applications. Installation is straightforward: seat the card in an open PCI Express slot, connect the cables, and the operating system recognizes the ports as standard Ethernet interfaces.

Whether you manage a data center, run a home lab, or simply want a smoother path to 10 Gigabit speeds, the Lenovo 4XC0G88856 provides a reliable way to boost network performance while keeping your existing copper infrastructure in place.

Highlights:

• Two 10 Gigabit Ethernet Base-T ports
• Intel X550 controller for consistent, low-latency throughput
• PCI Express connectivity for high-bandwidth data paths
• Works with CAT6a and CAT7 copper cabling; no fiber required
• Compatible with desktops and servers in virtualized or storage-intensive environments
