5.1 MMC Firmware
The Module Management Controller (MMC) is a crucial component of any AMC module. Besides acting as a
regular IPMI management controller (sensor monitoring, event generation, etc.), it also provides an
interface to all necessary data related to module power requirements and implemented interfaces (E-
Keying). Further, it plays an active role in the module hot swap state management. The carrier IPMI
Controller (IPMC) communicates with the MMC using the local IPMB (IPMB-L) bus. In an ATCA/AMC
environment, it is the IPMC that actually turns on/off module (payload) power. However, before the IPMC
enables the module payload power, various criteria must be satisfied by both the carrier and the module,
including handle switch state, power requirements and capabilities, matching interfaces, current module hot
swap state, and any other special conditions as specified by the Shelf Manager policy.
