5.1.1
The power supply must provide a 5V Standby power source for the platform to provide any
management functionality. 5V Standby is a low power 5V supply that is active whenever the
system is plugged into AC power. 5V Standby is used by the following onboard management
devices:
5.1.2
The IPMI specification defines a standardized, abstracted, message-based interface between
software and the platform management subsystem, and a common set of messages
(commands) for performing operations such as accessing temperature, voltage, and fan
sensors, setting thresholds, logging events, controlling a watchdog timer, etc.
IPMI includes a set of records called Sensor Data Records (SDRs) that make the platform
management subsystem self-descriptive to system management software. The SDRs include
software information such as how many sensors are present, what type they are and what
events they generate. The SDRs also include information such as minimum and maximum
ranges, sensor type, accuracy and tolerance, etc., that guides software in interpreting and
presenting sensor data.
Together, IPMI Messaging and the SDRs provide a self-descriptive, abstracted platform
interface that allows management software to automatically configure itself to the number and
types of platform management features on the system. In turn, this enables one piece of
management software to be used on multiple systems. Since the same IPMI messages are
used over the serial/modem and LAN interfaces, a software stack designed for in-band (local)
management access can readily be re-used as an out-of-band remote management stack by
changing the underlying communications layer for IPMI messaging.
5.1.3
An IPMI-compatible ‘Sensor Model’ is used to unify the way that temperature, voltage, and other
platform management status and control is represented and accessed. The implementation of
this model is done according to command and data formats defined in the Intelligent Platform
Management Interface Specification.
The majority of monitored platform elements are accessed as logical Sensors under this model.
This access is accomplished using an abstracted, message-based interface (IPMI messages).
Instead of having system software access the platform monitoring and control hardware
registers directly, it sends commands, such as the Get Sensor Reading command, for sensor
Revision 2.1
Management Controller (mBMC) and associated RAM, Flash, and SEEPROM which are
used to monitor the various system power control sources including the front panel
Power Button, the baseboard RTC alarm signal, and power on request messages from
the auxiliary IPMB connector and PCI SMBus.
On-board NICs that support IPMI-over-LAN and LAN Alerting, Wake-On LAN, and Magic
Packet* operation.
