This connector is used to connect a chassis power On/Off button using an adapter cable. This connector is closely related to JP2
configuration. The use of this connector is briefed as follows:
1. Using ATX power: CN4 connects to a power switch which functions as a soft-power-on switch managed by
BIOS power-on setting, and the JP2 jumper should be left open.
2. Using AT power: The pins on JP2 are shunted by a jumper cap. The default configuration of JP2 is shunted.
