1 IPMI Overview
The Kontron IPMI implementation fully supports the Intelligent Platform Management Interface spec-
ification. The IPMI functionality operates under an autonomous management controller even if the
board is held in reset or power-down mode by a management card within a system designed for high
availability.
While the IPMI implementation is fully compliant with IPMI v2.0 and has been designed to operate with
any system management software (SMS) that respects this specification, can be easily integrated with
the Service Availability Forum — Hardware Platform Interface (SAF HPI) specification.
More information about Service Availability can be found on the following website:

For board-specific IPMI information, refer to the IPMI chapter of the user guide provided with the Com-
pactPCI board or the AMC module.
2 IPMI Controller Configuration
2.1 IPMI in a CompactPCI Chassis
IPMI is an extensible and open standard that defines autonomous system monitoring. It is autonomous
because every management controller within a CompactPCI chassis monitors its own sensors and sends
critical events through a dedicated bus to the BMC that logs it into a non-volatile System Event Log
(SEL). The IPMI implementation includes a device SDR repository module that allows the user's system
management software to detect all system components and build a database of all management con-
troller sensors.
Kontron's IPMI implementation in the CompactPCI environment is compliant with the PICMG 2.9 R1.0
specification. This specification defines the pinout of the J1 and J2 CompactPCI connectors as well as
the addressing scheme.
Each CompactPCI board is equipped with an IPMI controller acting either as a BMC or as an SMC. There
should be only one BMC in the chassis, or at least on the IPMB segment. The BMC may reside either on
a board, or on an external system management card, or in a shelf management controller (ShMC). The
specification allows all of these variants. As a BMC in the system slot, the board supports dual-ported
IPMB (IPMB-0 to the SMCs and IPMB-1 to the external segments via the CompactPCI backplane connec-
tor). The BMC administrates the SEL and the SDRR for the complete system. In a CompactPCI chassis,
there can be several SMCs. The SMC administrates the sensor and FRU data of the board and makes it
available to the BMC. Each SMC can be connected to the BMC via a dedicated bus (IPMB-0).
