The HP Intel I225-V Single Port 2.5GbE PCIe NIC (406L9AA) is an HP-qualified network interface card that adds a 2.5 Gigabit Ethernet RJ-45 port to an HP business desktop. It suits users whose office, NAS or Wi-Fi 6/6E access points already run on 2.5GbE switching, or who need a second wired port for a separate network. The card uses the Intel Ethernet Controller I225-V, which supports 2.5 Gb/s as well as 1 Gb/s and 100 Mb/s over standard Cat5e or better cabling, and fits a PCIe slot. HP lists it for the HP EliteDesk 800 G8 small form factor and tower and the HP Pro 200 G8 microtower and small form factor. The card measures about 68.7 x 65.3 x 15.7 mm and weighs 50 g. Buying the HP option part rather than a generic card keeps the configuration within HP's supported and tested options. One-year limited warranty.
