4.10 Ethernet
The Intel
®
82583V, a fully-integrated Gigabit Ethernet Media Access Control
(MAC) provides 10/100/1000Mb/s Ethernet interface. The Intel
®
82583V is
connected to Port 2 of the PCIe x1 in the PCH. Gigabit transformer has to be
designed on the Carrier Board.
The integrated GbE controller contains power management registers for PCIE,
so it supports the Advanced Configuration and Power Interface (ACPI)
specification. This enables the network-related activity (using an internal host
wake signal) to wake up the host.
