ACPI Mode Notification
The BIOS notifies the BMC when the system enters and exits ACPI mode. The BMC, in turn,
notifies the ME. The NM power-limiting functionality is only available when the system is
operating in ACPI mode (an ACPI-compliant operating system is running).
4.4.7
Persistence Across Boots
Data passed to the ME will persist across boots, but will not persist across AC power loss.
4.5 Power Management Bus (PMBUS)
The BMC firmware implements power-management features based on the Power Management
Bus (PMBus) 1.1 Specification. The following sensor types are supported for systems that
contain PMBus-compliant power supplies and a PMBus-compliant power distribution board.
Power Supply Input Power Sensor
Power Supply Output Current Sensor
