IPMI Functions List 
The AMC-S402 module employs a Module Management Controller (MMC) as specified in the 
AMC.0 specification. The MMC provides an Intelligent Platform Management Interface (IPMI) 
which will communicate with the ATCA and MicroTCA shelf managers. This MMC controls 
and monitors the following: 
 
  Hot swap communication with the shelf manager 
  Inlet air temperature 
  Voltage monitoring 
  Electronic keying as described in the AMC.0 specification 
  FRU information 
  Drives LED indicators for Hot Swap, In Service, and Out of Service 
7.1  IPMI and Management Controller (IPMC) 
The design features an IPMI controller consisting of a 16-bit microcontroller, flash 
and SRAM.  The microcontroller uses I
2
C interface to communicate the shelf 
management controller (ShMC), and sensors and MMC devices on AMC modules. 
 
  An I2C connection provides the communication path between the MMC the 
temperature sensor.  The I2C serial bus also routes to the SFP+ modules. 
  Support hot-swap operation as defined for AMC modules in PICMG AMC.0 
specification “Fail-safe flash update” - if interrupted at anytime, the MMC 
firmware is still able to respond and re-flash. 
  “I2C hang recovery” - able to detect and recover from an I2C bus hang. 
7.2  Sensor Data Records 
The MMC monitors the status of the module and provides this data so the shelf 
manager can read it. Below are the SDRs that the AMC-S402 module creates.
