Power rail switched on in state S0 only.

Connected to SMBus via switch, isolated after PCI reset.

Stuffing option, default is the HDA option.

Unswitched power rail (switched on always).

The expansion interface header footprint is available on both sides of the board, top (J-EXPT) and

bottom (J-EXPB). Nevertheless the bottom side connector is stuffed only on customers request.

WARNING: Neither the +3.3V pin, nor the +5V pin, nor the +12V pin are protected against a short

circuit situation! This connector therefore should be used only for attachment of an expansion board.

The maximum current flowing across these pins should be limited to 2A per power rail.
