IPMI Functions List
5.1 Overview
The RTM-ATCA-736X-DD module includes an MMC device for reporting status information to
the ATCA blade. This MMC utilizes an Intelligent Platform Management Interface (IPMI) which
will communicate with the AdvancedTCA. This MMC controls and monitors the following:
 Hot swap communication with the shelf manager
 Inlet air temperatures
 Voltage monitoring
 FRU information
 Drives OOS (out of service), IS (in service) and ATN (attention) LEDs
5.2 IPMI 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 AdvancedMC modules and the RTM, if installed.
 An I2C connection provides the communication path between the MMC and the
temperature sensor.
 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.
5.3 Sensor Data Records
The MMC monitors the status of the module and provides this data so it can be read by the shelf
manager. Below are the SDRs that the RTM-ATCA-736X-DD module creates.
