Chassis Management Module
The Chassis Management Module (CMM) provides single-chassis management. The CMM is used to
communicate with the management controller in each compute node (IMMv2 in Intel processor-based
compute nodes and FSP in POWER7

processor-based compute nodes) to provide system monitoring,
event recording and alerts, and to manage the chassis, its devices, and the compute nodes.
The chassis supports up to two CMMs. If one CMM fails, the second CMM can detect its inactivity and
activate itself to take control of the system without any disruption. The CMM is central to the management
of the chassis and is required in the Enterprise Chassis.
