Intel® Ethernet Server Adapter I210

Low-power, small-footprint, single-port gigabit network controller with support 

for IEEE* 802.1Qav Audio-Video Bridging for Desktop, Server, and Embedded applications.


       PCI Express X1 Intel® Ethernet Server Adapter I210, specially designed to setup a long-distance link with a file server or 

a remote workstation. Compatible with a Multi-mode Gigabit 1000SX transceiver for fiber connection up to a 500-meter distance

or a Single Mode Gigabit 1000LX/ WDM transceiver for fiber connection up to a longer distance (kms).

       Low-halogen1 single-port PCI-Express* 10/100/1000 Ethernet adapter

       Innovative power management features including Energy Efficient Ethernet (EEE), DMA Coalescing, ultra-compact design, 

         and a unique ventilated bracket for increased efficiency and reduced power consumption

       IEEE 802.1Qav Audio-Video-Bridging (AVB) for tightly controlled media stream synchronization, buffering, and reservation
