is a hardware reset switch which can be used to reset the
system without turning off the power
DVI-I Connector (DVII1):
ATX Power Button Connector (PSW1)
USB 2.0 Ports (J8): The board provides 4 USB 2 0 type A
ports Dual ports on the front panel (Reference NO : J7),
one port on the back panel (Reference No : USB2), and
one USB pitch (Reference No : J8) on the board
LCD Module (LCM1): The LCD module connector is a
serial type port which can be connected to display the
real-time operating status and configuration parameters
of the system
Note: In order to connect the LCM, you will need
to adjust BOTH Jumper J4 and J6 accordingly
Note that COM1 will be disabled when the jumper
setting is set to LCD Module use Refer to the COM1
