PCIE_​15_​TXP/SATA_​2_​TXP/GbE_​0C_​TXP

PCIE_​15_​TXN/SATA_​2_​TXN/GbE_​0C_​TXN

O

Differential transmit pairs to the Intel® Ethernet Connection I219 based on the PCIe interface. Refer to PCI Express* (PCIe*) for details on the PCI Express*transmit signals.

PCIE_​7_​RXP/GbE_​0B_​RXP

PCIE_​7_​RXN/GbE_​0B_​RXN

PCIE_​3_​RXP/GbE_​0A_​RXP

PCIE_​3_​RXN/GbE_​0A_​RXN

PCIE_​15_​RXP/SATA_​2_​RXP/GbE_​0C_​RXP

PCIE_​15_​RXN/SATA_​2_​RXN/GbE_​0C_​RXN

I

Differential receive pairs to the Intel® Ethernet Connection I219 based on the PCIe interface. Refer to PCI Express* (PCIe*) for details on the PCI Express* transmit signals.

GPP_​D10/SML0DATA

I/OD

System Management Link data signal interface to Intel® Ethernet Connection I219. Refer to System Management Interface and SMLink for details on the SML0DATA signal.

Note:The Intel® Ethernet Connection I219 connects to SML0DATA signal.

GPP_​D09/SML0CLK

I/OD

System Management Link data signal interface to Intel® Ethernet Connection I219. Refer to System Management Interface and SMLink for details on the SML0CLK signal.

Note:The Intel® Ethernet Connection I219 connects to SML0CLK signal.

GPD11/LANPHYPC

O

LAN PHY Power Control: LANPHYPC should be connected to LAN_​DISABLE_​N on the PHY. The PCH will drive LANPHYPC low to put the PHY into a low power state when functionality is not needed.

Note:LANPHYPC can only be driven low if SLP_​LAN# is de-asserted.

GPD09/SLP_​LAN#

IO

LAN Sub-System Sleep Control: If the Gigabit Ethernet Controller is enabled, when SLP_​LAN# is de-asserted it indicates that the PHY device must be powered. When SLP_​LAN# is asserted, power can be shut off to the PHY device.

Note:If Gigabit Ethernet Controller is statically disabled via BIOS, SLP_​LAN# will be driven low.

GPD2/LAN_​WAKE#

I

LAN_​WAKE#: LAN Wake Indicator from the GbE PHY.

Note:LAN_​WAKE# functionality is only supported with Intel PHY I219. Connection of a third party LAN device’s wake signal to LAN_​WAKE# is not supported.
