Product Overview

The Intel Ethernet Controller X540 is a derivative of the 82599, the Intel® 10 GbE Network Interface Controller (NIC) targeted for blade servers. Many features of its predecessor remain intact; however, some have been removed or modified as well as new features introduced.

The Intel Ethernet Controller X540 includes two integrated 10GBASE-T copper Physical Layer Transceivers (PHYs). A standard MDIO interface, accessible to software via MAC control registers, is used to configure and monitor each PHY operation.
