Figure 2-7: COM Ports and LED Indicators
Two of the serial ports (COM1 and COM2) are interfaced to the ITE IT8712 super I/O,
through the low pin count (LPC) bus to the ICH9M Southbridge. The remaining four serial
ports (COM3, COM4 and COM5) are connected to the ICH9M LPC bus through a Fintek
serial port controller.
2.4.2 LAN Connectivity
One of the PCI Express (PCIe x1) lanes from the ICH9M Southbridge is interfaced to a
PCIe gigabit Ethernet (GbE) controller. The Ethernet controller is then connected directly
to the RJ-45 connector on the rear panel and provides external PCIe GbE connectivity.
