Product Features

1. Dual Independent 2.5G Network Ports

Each RJ45 port runs at full 2500Mbps independently, with auto-negotiation for 2500/1000/100Mbps speeds. Works with standard Cat5e or better Ethernet cables to achieve full 2.5G performance, greatly reducing transfer time for large files, high-bitrate video streams and NAS data backup

2. Silent Passive Cooling Design

Large-area aluminum alloy heatsink dissipates heat efficiently without any fan. Completely silent operation makes it suitable for noise-sensitive home and office environments, and ensures stable full-speed performance even during 7×24 hour non-stop operation.

3. Universal PCIe Interface & Chassis Compatibility

Standard PCIe x1 interface fits all mainstream desktop motherboards and works in x4 / x8 / x16 slots. Two interchangeable brackets cover most chassis types: full-height for standard ATX towers, low-profile for slim SFF desktops and 2U rackmount servers.

4. Broad System & Software Support

Compatible with Windows 10 64-bit, Windows 11 64-bit and mainstream Linux distributions. Works with popular soft router firmware (ROS, OpenWrt) and virtualization systems (ESXI), widely used in home labs, small office networks, storage servers and industrial control devices.

Important Notes

1. To achieve full 2500Mbps speed per port, use Cat5e or higher Ethernet cables, and ensure your connected router/switch/NAS also supports 2.5Gbps rate.
2. Driver installation is required. Please download the official Intel I226 driver for your system. 
3.This card uses a PCIe x1 interface and can be inserted into PCIe x4/x8/x16 slots. It is NOT compatible with legacy PCI slots.
