Sensors Implemented on the AM5030
The MMC includes many sensors for voltage or temperature monitoring and various others for
pass/fail type signal monitoring.
Every sensor is associated with a Sensor Data Record (SDR). Sensor Data Records contain
information about the sensors identification such as sensor type, sensor name, sensor unit.
SDRs also contain the configuration of a specific sensor such as threshold, hysteresis or event
generation capabilities that specify sensor's behavior. Some fields of the sensor SDR are con-
figurable using IPMI commands others are always set to built-in default values.
Finally, one field, which is the sensor owner, must reflect the module addresses that allow the
AMC Carrier to identify the owner of the sensor when it is scanned and merged into the AMC
Carrier's SDR repository.
From the IPMI perspective, the MMC is set up as a satellite management controller (SMC). The
MMC supports sensor devices IPMI commands and uses the static sensor population feature
of IPMI. All Sensor Data Records can be queried using Device SDR commands.
Each sensor has a name field in its SDR. The sensor name has a prefix, which is automatically
adapted, dependent on the physical position of the module in a carrier or in a µTCA chassis.
The following prefixes are used for all sensors of an AMC module:
Module sensors that have been implemented are listed in the sensor list below.
