 Payload Boot Bank Selection
 Serial Line Selection
 Built-in Terminal Server
 Settable Graceful Shutdown Timeout
 IPMI Hardware Watchdog Timer
 Failsafe
 Local System Event Log (SEL)
The IPMC at the front board is acting like a carrier IPMC. It retrieves the sensor information of
the MMC and creates a SDR repository providing direct access to all sensors within the system.
The IPMC is implemented as the managed FRU #0 and the MMC as FRU #1. All commands
which are directed to the MMC will be bridged by the IPMC.
The P4080 communicates with the IPMC using the Keyboard Controller Style (KCS) interface of
the H8S. The FRU inventory, SEL events, and the SDR information is stored in external I2C
EEPROMS. This enables post-mortem analysis when the system processor becomes disabled.
IPMB buffers on both IPMB-0 busses are used to isolate a faulty IPMB bus from the backplane.
