5.3.1 Power Supply Interface Signals
The mBMC supports two power supply control signals: Power On and Power Good. The Power
On signal connects to the chassis power subsystem through the chipset and is used to request
power state changes (asserted = request Power On). Power Good is a signal from the chassis
power subsystem indicating current power state (asserted = power is on).
