Intel® Server System "Emerald Ridge” Integrated BaseboardManagement Controller EPSAppendix A: OEM SDR RecordsPower Unit Map RecordA Power Unit Map SDR is an OEM SDR (type C0h) with the Intel manufacturer’s ID (343 =157h). The record contains a sub-type identifier (02h).A Power Unit Map contains information about the power supply sensor association andredundancy definition for the associated power unit sensor. The sensor numbers for thepower unit redundancy sensor and associated power supply sensors are provided.Table 80.
