Chapter 4: Motherboard Connections
VGA Connections
There are two VGA connections in your system. The rear VGA port is located at JVGA on the
rear I/O panel, and the front VGA header is located at JFP2 on the motherboard. These VGA
connections provide analog interface support between the computer and the video displays.
Refer to the layout below for the locations of VGA connections.
COM Ports
Two COM (communication) ports that support serial link interface are on this motherboard.
COM1 is located on the rear I/O panel. COM2 is located next to PCIe Slot 1.
LAN Ports (LAN1/LAN2 & BMC LAN)
Two Ethernet LAN ports (LAN1/LAN2) and an BMC dedicated LAN (BMC LAN) are located
on the rear I/O panel. LAN1/LAN2 ports support 1 GbE LAN connection (via the Intel i350
LAN controller) on the X12DPi-N6, and support 10 GbE LAN connection (via the Intel X550
LAN controller) on the X12DPi-NT6. The dedicated BMC LAN, located above the USB2/3
ports on the rear I/O panel, provides LAN support for the BMC (Baseboard Management
Controller). All of these LAN ports accept RJ45 cables. Please refer to the LED Indicator
section for LAN LED information.
