 Serial Line Selection
 Local System Event Log
The IPMC at the front board acts like an IPMC carrier. It retrieves the sensor information of the
MMC and creates a Sensor Data Record (SDR) repository providing direct access to all sensors
within the system. The IPMC is implemented as the managed FRU #0 and the MMC as managed
FRU #1. All commands directed to the MMC will be bridged by the IPMC.
The Intel CPU communicates with the IPMC using the KCS interface of the IPMC. The FRU
inventory, System Event Log (SEL) events, and the SDR information are stored in external I2C
EEPROMs. This enables post-mortem analysis when the system processor becomes disabled.
Registers within the Glue Logic FPGA can be accessed by the IPMC via I2C bus. This enhances
the capabilities of the IPMC. The Glue Logic FPGA is used to monitor the CPU status, the
payload reset cause, the power failure registers, and to control the BIOS boot bank selection.
