2.6.3 Shelf FRU Information
The SEEPROMs are located on the Alarm Display Panel (ADP1440-D). Information is
accessed by using the standard IPMI FRU commands over the IPMC. Refer to the
Centellis
4440/4620 Control via IPMI Programmer’s Reference
listed in
Appendix A
.
The SAM1620-D 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
Shelf Management Controller (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.
