14 CIM_PhysicalElement
CIM_PhysicalPackage
The CIM_PhysicalPackage class listed in Table 2-2 represents physical elements that contain or host
other components. Examples are a rack enclosure or an adapter card with multiple functions.

Class Name: CIM_PhysicalElement
Parent Class: CIM_ManagedSystemElement
Property Description Data Type
CreationClassName See Table 1-2, “Common Properties of Classes.”
Manufacturer See Table 1-2, “Common Properties of Classes.”
Model The name by which the physical element is generally known. string
SerialNumber A manufacturer-allocated number used to identify the physical element. string
Tag Uniquely identifies the physical element and serves as the element’s key. The Ta g
property can contain information such as asset tag or serial number data. The key
for physical element is placed very high in the object hierarchy in order to identify
the hardware/entity independently, regardless of physical placement in or on
cabinets, adapters, and so on. For example, a hot-swappable or removable
component can be taken from its containing (scoping) package and temporarily
unused. The object still continues to exist and may even be inserted into a different
scoping container. Therefore, the key for physical element is an arbitrary string that
is defined independently of any placement or location-oriented hierarchy.

Property Description Data Type
Removable A CIM_PhysicalPackage is removable if it is designed to be taken in and out of the physical
container in which it is normally found without impairing the function of the overall package.
Boolean
Replaceable A CIM_PhysicalPackage is replaceable if it is possible to substitute a physically different
element for the original element, as in a field replaceable unit (FRU). For example, some
computer systems allow the microprocessor to be upgraded to one of a higher clock
rating. In this case, the microprocessor is said to be replaceable.
