C Buses
The two private I
2
C buses of the BMC, which are directly connected to the BMC, include
discrete temperature sensors, voltage sensors, an RTC, and an optional FRU EEPROM. There are
also routing resistors on the board that allow connection of these buses to the Glue CPLD as a
BOM option. The I
2
C addresses of the devices are shown in the following tables.
