Emerson 752I Manuel D’Utilisation

 IPMI Message Protocol

752i User’s Manual

The Zircon PM peripheral management controller supports IPMI commands to query board 
information and to control the behavior of the board. These commands provide a means 
to: 

• identify the controller

• reset the controller

• return the controller’s self-test results

• read and write the controller’s SROMs

• read the temperature, voltage, and watchdog sensors

• get specific information, such as thresholds, for each sensor

• read and write the Field Replaceable Unit (FRU) data

• reserve and read the Sensor Data Record (SDR) repository

• configure event broadcasts

• bridge an IPMI request to the public IPMB and return the response

• read and write the controller’s general-purpose I/O (GPIO)

• configure heartbeat broadcasts

 lists the IPMI commands supported by the Zircon PM along with the hexadecimal 

values for each command’s Network Function Code (netFn), Logical Unit Number (LUN), 
and Command Code (Cmd).

Device specific (OEM) completion codes–command-specific codes (also specific 
for a particular device and version). Interpretation of these codes requires prior 
knowledge of the device command set.
