NVMe Slots
Use the two NVMe slots (NVME1 and NVME2) to attach high-speed PCI-E storage devices.
I-SATA 3.0 and S-SATA 3.0 Ports
The X11DPG-SN has ten SATA 3.0 ports (I-SATA0-3, I-SATA4-7 and S-SATA0 and S-SATA1),
which are supported by the Intel C621 chipset. S-SATA0 can be used with Supermicro
SuperDOM, a yellow SATA DOM connector with power pins built in that does not require
external power cables. Supermicro SuperDOMs are backward-compatible with regular SATA
HDDs or SATA DOMs that need external power cables.
Control Panel
JF1 contains header pins for various control panel connections. See the figure below for the
pin locations and definitions of the control panel buttons and LED indicators.
All JF1 wires have been bundled into a single cable to simplify this connection. Make sure
the red wire plugs into pin 1 as marked on the motherboard. The other end connects to the
control panel PCB board.

VGA Port
The VGA connector (JVGA) is located below the JSIOM slot and next to JTPM1 connector.
Use this connection for VGA display.
Serial Port
There is one COM connector (JCOM1) near the I/O back panel, next to the IPMI LAN
connector. The COM connector provides serial communication support.
