CIM_PhysicalElement is a CIM-defined class. The CIM_PhysicalElement class contains the subclasses shown in Figure 2-1.
Figure 2-1. CIM_PhysicalElement Class Structure
CIM_PhysicalElement
Subclasses of the CIM_PhysicalElement class listed in Table 2-1 define any component of a system that has a distinct physical identity. Physical elements are tangible managed system elements (usually actual hardware items) that have a physical manifestation of some sort. By contrast, processes, files, and logical devices are not classified as physical elements. A managed system element is not necessarily a discrete component. A single card (which is a type of physical element) can host more than one logical device. One card, for example, could implement both a modem and a local area network (LAN) adapter. In this case, the card would be represented by a single physical element associated with multiple logical devices.
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 Tag 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.
string
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.

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.
Boolean
CIM_PhysicalFrame
The CIM_PhysicalFrame class described in Table 2-3 contains other frame enclosures such as racks and chassis. Properties like VisibleAlarm or AudibleAlarm, and data related to security breaches are also members of this class.

CIM_Slot
The CIM_Slot class described in Table 2-11 represents connectors into which packages are inserted. For example, a physical package that is a hard drive can be inserted into a small computer system interface-single connector attachment (SCSI-SCA) slot. As another example, a card can be inserted into a 16-, 32-, or 64-bit expansion slot on a host board.
