4.2.2 LAN2 – Intel I211AT GbE Controller
Intel Ethernet I211 controller is a single port, compact, low power component that supports GbE
designs. The I211 offers a fully-integrated GbE Media Access Control (MAC), Physical Layer (PHY)
port and supports PCI Express 2.1 (5GT/s). The I211 enables 1000BASE-T implementations using
an integrated PHY. It can be used for server system configurations such as rack mounted or
pedestal servers, in an add-on NIC or LAN on Motherboard (LOM) design. Another possible system
configuration is for blade servers as a LOM or mezzanine card. It can also be used in embedded
applications such as switch add-on cards and network appliances.
One independent interface is used to connect the I211 port to external devices. The following
protocol is supported: MDI (copper) support for standard IEEE 802.3 Ethernet interface for
1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab).
