3.9 Ethernet Connectors
The KTQ45 boards supports 2 channels of 10/100/1000Mb Ethernet one based on Intel® Boazman-LM
WG82567LM Gigabit PHY with AMT 5.0 support (ETHER1) and the other based on Intel® Hartwell 82574L
PCI Express controller (ETHER2).
In order to achieve the specified performance of the Ethernet port, Category 5 twisted pair cables must be
used with 10/100MB and Category 5E, 6 or 6E with 1Gb LAN networks.
The signals for the Ethernet ports are as follows:
Signal Description
MDI[0]+ / MDI[0]- In MDI mode, this is the first pair in 1000Base-T, i.e. the BI_DA+/- pair, and is the
transmit pair in 10Base-T and 100Base-TX.
In MDI crossover mode, this pair acts as the BI_DB+/- pair, and is the receive pair
in 10Base-T and 100Base-TX.
MDI[1]+ / MDI[1]- In MDI mode, this is the second pair in 1000Base-T, i.e. the BI_DB+/- pair, and is
the receive pair in 10Base-T and 100Base-TX.
In MDI crossover mode, this pair acts as the BI_DA+/- pair, and is the transmit
pair in 10Base-T and 100Base-TX.
MDI[2]+ / MDI[2]- In MDI mode, this is the third pair in 1000Base-T, i.e. the BI_DC+/- pair.
In MDI crossover mode, this pair acts as the BI_DD+/- pair.
MDI[3]+ / MDI[3]- In MDI mode, this is the fourth pair in 1000Base-T, i.e. the BI_DD+/- pair.
In MDI crossover mode, this pair acts as the BI_DC+/- pair.
Note: MDI = Media Dependent Interface.
3.9.1 Ethernet Connectors 1 and 2 (ETHER1 and ETHER2)
Ethernet connector 1 (positioned to the right) is mounted together with USB Ports 4 and 5.
Ethernet connector 2 (positioned to the left) is mounted together with USB Ports 2 and 3.
The pinout of the RJ45 connector is as follows:

Note: Do not use PCB silkscreen to identify the position of ETHER1/ETHER2. Silkscreen might indicate
LAN1 and LAN2 in opposite order.
