PCA-6184, ed. 1 User’s Manual 24
2.13 ATX Power Control Connectors (CN20 and 21)
2.13.1 ATX feature (CN20) and soft power switch (CN21)
The PCA-6184 can support an advanced soft power switch function if an
ATX power supply is used. To enable the soft power switch function:
1. Connect the 3-pin plug of the cable to CN20 (ATX feature connec-
tor).
2. Connect the power on/off button to CN21. (A momentary type of
button should be used.)
Note: If you will not be using an ATX power connector,
make sure that pins 2-3 of CN20 are closed.
Warnings: 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.
Important: Make sure that the ATX power supply can take
at least a 720 mA load on the 5 V standby lead
(5VSB). If not, you may have difficulty powering
on your system and/or supporting the "Wake-
on-LAN" function.
