Shelf FRU Information

The SEEPROMs are located on the Alarm Display Panel (ADP); the FRU information for the
PEM is contained in FRU 0. This information is accessed by using the standard IPMI FRU
commands over the IPMC. Refer to the AXP1620 Subsystem IPMI Programmer's Reference
listed in Appendix A, Related
The SAM queries all IPMCs during system startup to determine whether they are a source of
shelf FRU information and then uses that information to complete initialization. The information
is cached as FRU 254 on the active ShMC (0x20). The information in the SEEPROM is only
needed when the SAMs are first inserted or when the shelf is powered on for the first time. The
redundancy feature provides the shelf-specific information should one SEEPROM be
nonfunctional.
