Hardware Management Overview—MPCBL0010 SBC

The FWUM can handle two firmware codes that are stored in two external SEPROMs. If a failure occurs during a firmware upgrade, the FWUM automatically rolls back to the redundant IPMC firmware image.

10.2Sensor Data Record (SDR)

Sensor Data Records contain information about the type and number of sensors in the baseboard, sensor threshold support, event generation capabilities, and the types of sensor readings handled by system management firmware. SDRs also contain the configuration of a specific sensor such as threshold/hystheresis, and event generation capabilities that specifies sensor behavior. Some fields of the sensor SDR are configurable through IPMI v1.5 commands and are set to built-in default values.

The MPCBL0010 SBC management controller is set up as a satellite management controller (SMC). It supports sensor devices, and uses the IPMI dynamic sensor population feature of IPMI v1.5 to merge the hot-swapped AdvancedMC sensors with the MPCBL0010 SBC sensor population. Normally, the AdvancedTCA* ShMC is informed about an AdvancedMC insertion is through the AdvancedMC carrier hot swap sensor. However, to remain compliant to IPMI v1.5, the IPMC updates the sensor population change indicator timestamp accessible through the Get Device SDR Info command. All SDRs can be queried using Device SDR commands to the firmware. Baseboard sensors that have been implemented are listed in the following table.
