The IPMC implements a Device Sensor Data Record (SDR) Repository that contains SDRs for
the IPMC, the FRU device, and each sensor. A system management controller may use the
Get Device SDR command to read the repository and dynamically discover the capabilities
of the board. Refer to the IPMI specification (listed in
the IPMC, the FRU device, and each sensor. A system management controller may use the
Get Device SDR command to read the repository and dynamically discover the capabilities
of the board. Refer to the IPMI specification (listed in
) for more information on
using Sensor Data Records and the Device SDR Repository.
Under certain circumstances, some sensors connected to the IPMC can generate Event Mes-
sages for the system management controller. To enable these messages, the system man-
agement controller must send a Set Event Receiver command to the IPMC, along with the
address of the Event Receiver.
