Sensors
The system's various sensors are subordinated to the /system1 instance. The instance's CIM
class membership depends on the sensor type: Discrete sensors belong to the CIM_Sensor
class; numeric sensors are instances of the CIM_NumericSensor class (which is derived from
CIM_Sensor). The CLP class tag depends on the particular sensor's function.

Properties:
Discrete and numeric sensors:
• Description shows the sensor name, IPMI device id, type, and associated target.
• SensorType and OtherSensorTypeDescription describe the sensor type.
• PossibleStates lists the possible states this sensor can be in.
• CurrentState shows the current sensor state.
Numeric sensors only:
• BaseUnit, UnitModifier, and RateUnits describe the sensor reading unit.
• CurrentReading shows the current sensor reading.
• NominalReading, NormalMin, and NormalMax represent the normal range for the
sensor readings.
• MinReadable and MaxReadable describe the maximum possible range of sensor
readings.
• LowerThresholdFatal, LowerThresholdCritical, LowerThresholdNonCritical,
UpperThresholdNonCritical, UpperThresholdCritical, and UpperThresholdFatal
represent the thresholds between the possible sensor states.
Supported commands:
• RESET invokes an IPMI Sensor Rearm Events command for the specified sensor.
• SET can be used to manipulate the various sensor thresholds (numeric sensors
only).
/system2/account#
The account# instances belong to the CIM_Account class and represent the 63 available BMC
user slots, including those that are currently empty.
