PCI Express Intel® I225 multi-gigabit Ethernet controller

supporting mobile, desktop, workstation, value-server, or embedded space-constrained designs.


PCI Express Intel I225 2.5G Network card, adopts Intel a high performance network controller i225-V. This controller with

Base-T copper networking interface, provides compact, single-port integrated multi-gigabit (up to2.5G) –MDI (Copper) standard IEEE802.3 Ethernet interface for 2500BASE-T,1000BASE-T,100BASE-TX,10BASE-TE connections, and it canalso support Intel vPro echnology on specific Intel platforms . It is designed for use on any mobile, desktop, workstation, value-server, or industrial designs that have critical space constraints.
