The CIM_Dependency class is an association used to establish dependency relationships between two managed system elements. CIM_Dependency shown in Figure 5-1 does not have a parent class because it is a relationship or association between two elements.
Figure 5-1. CIM_Dependency Class Structure
Each class derived from CIM_Dependency has an element called an antecedent that represents the independent object in this association, and another element called a dependent that represents the object that is dependent on the antecedent. For example, consider two managed system elements: Chassis1 and PowerSupply3. Chassis1 is the antecedent element because a managed power supply would always be either contained in, or grouped with, a chassis.
DELL_FanSensor
The DELL_FanSensor class described in Table 5-1 defines a Dell-specific association between a fan and a sensor. The CIM_PackageFanSensor class contains fans that assist in cooling the entire package as opposed to a fan that is dedicated to cooling only some of the components in the package.

Class Name:
DELL_FanSensor
Parent Class:
CIM_Dependency
Element
Description
Antecedent
CIM_Tachometer refers to the tachometer (fan sensor) that measures the RPM of the fan.
Dependent
CIM_Fan refers to the fan whose revolutions are measured by the tachometer.
CIM_PackageTempSensor
The CIM_PackageTempSensor class listed in Table 5-2 contains temperature sensors that are often installed in a package such as a chassis or a rack to assist in the monitoring of the package in general. This relationship is described by the CIM_PackageTempSensor association.
