2.8. IPMB (Intelligent Platform Management Bus)

An IPMB ("Intelligent Platform Management Bus") port is defined for platform management functions. The IPMB is used (optionally) with a Carrier based
BMC (Board Management Controller) Master. On the Module, the IPMB should be routed to and used with a MMC (Module Management Controller).
The Module IPMB is a slave port and uses I2C signaling.
IPMB through a MMC is build option support and by project basis
The conjunction between Module MMC and Carrier BMC is still in developing (TBC)
