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.

Power Button
The Power Button connection is located on pins 1 and 2 of JF1. Momentarily contacting both
pins will power on/off the system. This button can also be configured to function as a suspend
button (with a setting in the BIOS - see Chapter 4). To turn off the power when the system
is in suspend mode, press the button for 4 seconds or longer. Refer to the table below for
pin definitions.
RAID Key Header
A RAID Key header is located at JRK1 on the motherboard. The RAID key is used to support
CPU NVMe SSD.
