Single-port Intel I210 adapter

This PCI Express 2.1 x1 network card uses the Intel I210 controller to provide one copper RJ45 port. It is intended for servers or workstations that need a reliable wired Ethernet connection through a standard or low-profile bracket.

Replaces older 10/100 controllers

The card upgrades systems limited to Fast Ethernet by adding 10/100/1000 Mbps capability on existing Category-5 cabling up to 100 meters. The jump is worth it when the motherboard lacks a Gigabit port or when a dedicated Intel controller is preferred for driver stability across Windows, Linux and VMware ESXi environments.

1.25G line rate with Category-5 reach

The 2.5 G T/s lane delivers full Gigabit throughput with headroom for protocol overhead, while the single RJ45 port handles links up to 100 meters on standard copper. It runs out when more than one physical network connection is required or when the slot budget cannot spare even a single PCIe lane.
