I/O Shield Connector
The P2-112A is equipped with an I/O back panel. Please use the appropriate I/O
shield (figure 3).
Power-On/Off (Remote)
The P2-112A 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 P2-112A 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 P2-112A’s onboard circuit
controller) that can be controlled by the operating system. Windows 95 will control
this when the user clicks that they are ready to Shutdown the system.
