PCI-E I225 2.5G Ethernet Server Network Card (I225‑V controller) Key benefits - Faster wired networking: single‑port multi‑gigabit Ethernet up to 2.5Gb/s for higher throughput on existing copper infrastructure. - Backward compatibility: works with legacy 1Gb, 100Mb and 10Mb networks so it integrates with mixed-speed environments. - Small, versatile form factor: suited for desktops, workstations, value servers, mobile devices or industrial systems where space is limited. - Reliable, standards‑based connectivity: uses the proven I225‑V Base‑T Ethernet controller and IEEE Ethernet standards for predictable interoperability. Main features and specifications - Controller: Intel I225‑V high‑performance Ethernet controller. - Interface: PCI‑Express (PCI‑E) compliant; PCI specification revision 3.1 (5.0 GT/s). - Port: Single RJ45 copper port supporting multi‑gigabit Base‑T. - Speeds supported: Up to 2.5Gb/s (2500BASE‑T); backward compatible with 1000BASE‑T, 100BASE‑TX and 10BASE‑TE. - Standards compliance: Compatible with IEEE 802.3 Ethernet standards, including support for 2500BASE‑T (IEEE 802.3bz) and legacy Ethernet rates. - Cable: Standard copper (RJ45) network cabling. Performance and compatibility - Delivers higher bandwidth on existing Cat5e/Cat6 copper cabling without replacing infrastructure. - PCI‑E 3.1 interface ensures high host bus bandwidth (5.0 GT/s) for low latency and efficient data transfer. - Designed to support a wide range of platforms and technologies, including mobile devices, desktops, workstations, value servers and space‑constrained industrial designs. Practical use scenarios - Upgrade a desktop or workstation to 2.5GbE for faster file transfers, low‑latency collaboration, and improved access to high‑speed NAS storage. - Add a compact multi‑gigabit uplink to a value server or home lab server to increase network throughput without replacing switches or cabling. - Integrate into an industrial or embedded system with limited space to provide reliable, standards‑based wired Ethernet connectivity. Why choose this card - Straightforward path to multi‑gigabit wired networking using existing copper cables. - Industry‑standard controller and protocol support for interoperability and predictable behavior in mixed networks. - Compact and PCI‑E 3.1 compatible design for modern systems with space or slot constraints. Compatibility and installation notes - Requires an available PCI‑Express slot compatible with PCI‑E 3.1 (5.0 GT/s). - Uses a standard RJ45 copper cable connection; no fiber required. - Backward compatible with 1GbE, 100Mb and 10Mb networks and switches. This PCI‑E I225 2.5G Ethernet server network card provides a compact, standards‑based solution to add multi‑gigabit copper Ethernet to desktops, servers and industrial systems while maintaining compatibility with existing network infrastructure.
