EP-6VBA Board
Power-On/Off (Remote)
The EP-6VBA has a single 20-pin connector for ATX power supplies. For ATX
power supplies that support the Remote On/Off feature, this should be connected
to the systems front panel for system Power On/Off button. The systems power
On/Off button should be a momentary button that is normally open.
The EP-6VBA has been designed with “Soft Off" functions. You can turn Off the
system from one of two sources: The first is the front panel Power On/Off
button, and the other is the "Soft Off" function (coming from the EP-6VBA’s
onboard circuit controller) that can be controlled by the operating system. Win-
dows 95 will control this when the user clicks that they are ready to Shutdown the
system.
