Power-On/Off (Remote)
The EP-3WXA/4/4Y 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-3WXA/4/4Y 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 the button, and the other is the "Soft Off" function (coming from the EP-
3WXA/4/4Y’s onboard circuit controller) that can be controlled by the operating
system. Windows 95/98 will control this when the user clicks that they are ready
to Shutdown the system.
