4.4.2
Board Sensors
The Management Controller includes many sensors for voltage, current and 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 thresholds, hysteresis, event generation capabilities, etc. that specify the sensor’s behavior. Some fields of the sensor
SDR are configurable through IPMI v1.5 command and are set to a built-in initial value.
Module sensors that have been implemented are listed in the sensor list in Table 4-6.
4.4.2.1
Sensor List
The sensor name (ID string) has a name prefix which is ‘Sxx:’ in the lists below. When reading the sensor name after mod-
ule insertion this prefix becomes automatically adapted to the role (BMC or PM) and the physical position (slot number) of
the module in a rack. If the module’s Management Controller is set up as a BMC the prefix will be ‘BMC:’ independent of the
slot where it resides. If the module’s Management Controller is set up as a SMC the prefix will be ‘Sxx:’ where xx is the slot
number (e.g. 09).
