AT8402
The AT8402 management controller supports sensor devices and uses the IPMI dynamic sen-
sor population feature of IPMI v1.5 to merge the AMC hot swap sensor with the AT8402 sen-
sors population. AMC hot swap events indicated by this sensor are passed to the ShMC.
Additionally, the IPMC updates the sensor population change indicator timestamp accessible
through the Get Device SDR Info command to remain compliant to IPMI v1.5.
All SDRs can be queried using Device SDR commands. Base Board sensors that have been
implemented are listed below.
