Chapter 4 IPMI Controller
The IPMI controller on the XCPC-9100 works as an IPM (Intelligent Platform
Management) The FRU Information is used primarily to provide ‘inventory’ information
about this board in the CompactPCI Chassis. The FRU will provide the Supplier’s name,
Xembedded, part number, 609100-001 and version number(s), Rev 1.3. These items can
be read through the system IPMI software.
The XCPC-9100 uses an on-board micro controller for the IPMI function to support FRU
(Field Replaceable Unit) information per the IPMI 1.5 specification. This function
supplies the BMC (Base Management Controller) on the System Controller board with
the information to replace the XCPC-9100. The on-board IPMI controller receives
requests for this table information with the following commands and responses.
FRU Inventory Area Information
This command is used to obtain information about the size and access method of
the FRU Inventory data on the XCPC-9100.

Read FRU Data
This command returns the specified data from the FRU Inventory information area. No parsing of the FRU data is
performed by the IPMI subsystem; System management software is responsible for interpreting the FRU data.
