• Power Sequence
9 The MMC controls all the power rail enable/disable signals, which is essential to the
power sequencing. The power sequencing therefore is controlled by the MMC.
• Power monitoring
9 All the power rail monitoring is done. Any violation of the threshold vales triggers an
event and the MMC reports to the IPMC and shuts down the power to protect the board.
• FRU Information
9 The MMC provides a Master only I2C Interface which is connected to an EEPROM that
contains RTM information, the log, and the alarms.
• Sensor
9 The on board sensors are connected to a Master only I2C Interface of the MMC and
provide the collected information such as voltage and thermal values to the MMC per the
MMC’s request.
