A dual redundant IPMB that connects MCMCs and EMMCs in a MicroTCA Carrier.
Electrically and logically separate from the Local IPMB (IPMB-L).
IPMB-A, IPMB-B
Intelligent Platform Management Buses A and B, respectively. Refers to the two
redundant IPMBs that aggregate into IPMB-0.
IPMB-L or
Local IPMB
Connects AdvancedMC’s MMC with the MCH’s MCMC. Electrically and logically
separate from the MCMC’s IPMB-0.

AdvancedMCs including MCMC, optional ShMC, optional Fabric switch, and clock.
MicroTCA Carrier
Management Controller
(MCMC)
Management controller on the MCH. The required management controller that
interfaces to AdvancedMC MMCs via IPMB-L and to CU, PM, and OEM Module
EMMCs via IPMB-0.
MMC
The required management controller on an AdvancedMC Module which interfaces to
the MicroTCA Carrier Manager on the MCH via IPMB-L
Module
Refers to any MicroTCA Module types, including CU, PM, MCH, OEM Module, or
AdvancedMC
Payload
