MITX-CORE-820 Installation and Use (6806800M10D)

4.7

PCI Express

The MITX-CORE-820 has one x16 5G PCI-Express slot which supports graphics cards up to 75

W in power. The position of the PCI-Express slot follows the Mini-ITX Addendum Version 1.1 of

the microATX Motherboard Interface Specification Version 1.2.

The Cougar Point-mbl PCH has one x1 PCI-Express port (port 6) to the WG82579LM and one

x1 PCI-Express port (port 3) to the WG82574L. Port 7 will be used for a PCI-Express Mini Card

connector for WiFi/WiMAX, port 8 is used for DMC card slot.

LAN on Motherboard

The MITX-CORE-820 provides two GbE ports. One port uses the Intel 6 Series PCH integrated

MAC and the Intel WG82579LM GbE PHY. The Intel WG82579LM is connected to PCH through

the 1x PCI-Express. The other Gbe port uses Intel WG82574L controller (MITX-CORE-820 only).

The design provides two RJ-45 connectors supporting 10/100/1000 Base T. LAN is powered by

suspend well to support AMT and wake-on-LAN while in S5. WG82579LM uses +V3.3 M and

WG82574L uses +V3.3 A.

LAN connector has two integrated LEDs.
