2.10 IPMI
The AM4211 supports an intelligent hardware management system based on the Intelligent Platform
Management Interface (IPMI) Specification 2.0. It provides the ability to manage the power, cooling and
interconnect needs of intelligent devices, to monitor events and to log events to a central repository.
The MMC ("Module Management Controller") controls all hotswap and E-Keying processes required by ATCA.
It activates the board power supply and enables communication with the AMC carrier. The MMC manages the
Ethernet switch E-Keying and the baseboard ATCA feature. The controller is connected to the IPMC of the
ATCA carrier board via IPMB-L bus.
All voltages and currents on the board are monitored by the MMC. Three temperature sensors on the board
make sure that thermal conditions are met:
• Temp NPU (OCTEON Internal Sensor)
• Temp MMC
• Temp DIMM
For more information on the thermal design and management, consult the "Thermal Consideration" section.
