- PCIe interface: 1-lane PCI Express bus with 2.5/5 Gbps bandwidth for straightforward expansion in a desktop or workstation. - Onboard 2.5G port: One onboard 2.5G RJ-45 network port with an integrated 10/100/1000/2.5G transceiver for reliable multi-speed connectivity. - Flexible speed modes: Supports 2.5G and 1G Lite, plus 100 Mbps operation to ensure compatibility with older networks and devices. - Auto-negotiation with extended next-page: Automatically negotiates the best link speed and uses extended next-page functionality to improve compatibility with devices that support it. Benefits and what problems it solves: - Faster local transfers: Enables higher throughput on your workstation by connecting to 2.5G-capable switches or NAS devices, reducing bottlenecks for large file transfers and backups. - Broad compatibility: Automatically adapts to mixed networks by offering 2.5G, 1G Lite, and 100M modes, so you can upgrade without replacing other equipment. - Simple upgrade, lasting relevance: Adds a single high-speed port without major changes to your existing setup, while remaining compatible with older Ethernet standards. Typical use scenarios: - Desktop or workstation upgrade: Install this PCIe card to connect to a 2.5G switch or NAS for faster file access, backups, and media transfers while still working with legacy 1G/100M devices when needed. - Small office or home lab: Use in a PC or server to link to a mixed-speed network, enabling higher performance for local data transfers and testing with 2.5G-enabled storage or equipment. - Legacy-friendly networking: In environments with older switches or devices, rely on 1G Lite or 100M mode to maintain connectivity while gradually upgrading to 2.5G across devices.
