The PCA-6186 can support an advanced soft power switch function if an
ATX power supply is used. To enable the soft power switch function:
1. Take the specially designed ATX-to-PS/2 power cable out of the
PCA-6186's accessory bag.
2. Connect the 3-pin plug of the cable to CN20 (ATX feature connec-
tor).
3. Connect the power on/off button to CN21. (A momentary type of
button should be used.)
Note:
Warnings:
of CN21.
If you will not be using an ATX power connector,
make sure that pins 2-3 of CN20 are closed.
1. Make sure that you unplug your power sup-
ply when adding or removing expansion cards
or other system components. Failure to do so
may cause severe damage to both your CPU
card and expansion cards.
2. ATX power supplies may power on if certain
motherboard components or connections are
touched by metallic objects.
