Short both pins 3-5 and 4-6 of JP4 to enable the ATX function. In addition to connecting the 4-
pin ATX power control cable to J11, a toggle switch should be used to switch the board’s ATX
power on/off. The toggle switch is usually located on the chassis front panel. Pressing the switch
once will turn the power on, and pressing it again will turn it off. The toggle switch should be
connected to J16.
The last thing to do before your SBC-845D-VEA system can be turned on is to connect the 20-pin
ATX power cable to the backplane. By switching your ATX power on, the system goes into power
standby. Pressing the SBC-845D-VEA ATX power button should successfully turn on the system.
