Board Sensors
The Management Controller 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 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 Sensor List
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).
The sensor number is the number which identifies the sensor e.g. when using the IPMI command “Get Sensor Reading”.
Please note that ‘ipmitool’ accepts sensor numbers in decimal (e.g. ‘10’) or hexadecimal (e.g. ‘xxh’) notation.
Please note that the IPMI tool ‘ipmitool’ displays for command ‘ipmitool sdr list’ the contents of the sensor data record
repository (SDRR) of the whole rack if the SDRR is generated. The generation of the SDRR has always to be done new after
adding or subtracting any board to or from the rack.
For OEM (Kontron) specific sensor types and reading types in the following table please refer to the next chapter.
