Figure 4-1. JF1: Control Panel Pins
Control Panel
JF1 contains header pins for various control panel connections designed specifically for use
with Supermicro chassis. 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.

SD Card Port
The JSDCARD1 is the SD Card port for the system.
UltraO Riser Card LAN LED Header
JF2 is a header for the UltraO Riser Card LAN LED header.
SATA Ports
The H11DSU-iN has fourteen (14) SATA 3.0 ports (SATA0-13) that are supported by the
System on Chip.
NVMe Connections
Four NVM Express (NVMe) ports are located on the motherboard (two for each processor).
These ports provide high-speed, low-latency PCI-Exp. 3.0 x4 connections directly from the CPU
to NVMe Solid State (SSD) drives. This greatly increases SSD data-throughput performance
and significantly reduces PCI-E latency by simplifying driver/software requirements resulted
from direct PCI-E interface from the CPU to the NVMe SSD drives.
