Field Replaceable Unit (FRU) Information
The BMC controller will store the FRU information about the board and the rear panel cards. Each
device will have its own Address. This device is a 32K x 8 device used to hold information about
the card.
Host CPU controller = Device 0
Host CPU Rear Panel Card = Device 1
System Event Log Information
The BMC controller stores system event information in an 8K x 8 serial EEPROM device. Both the
in-band KCS interface and the out-of-band IPMB interface provide access to the System Event Log
(SEL). This allows SEL information to be accessed through the IPMB interface even if the system
is down.
