7 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

7.1IPMI and Management Controller (IPMC)

The design features an IPMI controller consisting of a 16-bit microcontroller, flash and SRAM. The microcontroller uses I2C 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.

7.2Sensor 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.
