Step6: The figure below is the TOGGLE SWITCH which is used to switch the
ATX Power on/off for SBC. Usually the TOGGLE SWITCH is located on
the chassis front panel. Press the switch button once will turn power on,
and press again to turn it off.
Q : In addition to the above description, is there anything to do to finish up
an ATX system ??
A : Yes. ROBO-678 needs to be configured to support ATX function for the
above cabling. Please move jumper JP3 to 3-5 short and 4-6 short (support ATX
function).
Q : How can I build up an AT system using ATX power supply
A : Do not forget to move JP3 of ROBO-678 back to 1-3 short and 2-4 short
(support AT function).
If the ATX power supply has a switch, such as ORION-300ATX, leave the
jumper of backplane connector (CN4) in step 1 and use the power supply switch
as the system power on switch.
In all cases, users may apply a 2-pin AT (on/off) switch over pin-3 and pin-4 of
the backplane connector (CN4) in step 1. However, power supply switch needs
to be moved to “on”, if there is one.
