CIM_Chip class

The CIM_Chip class represents the type of integrated circuit hardware, including ASICs, processors, memory chips, and so on.

Important  The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.

Members

The CIM_Chip class has these types of members:

Properties

The CIM_Chip class has these properties.

Caption
Data type: string
Access type: Read-only

Short textual description of the object. This property is inherited from CIM_ManagedSystemElement.

CreationClassName
Data type: string
Access type: Read-only

Name of the class or subclass used in the creation of an instance. When used with other key properties of the class, this property allows all instances of the class and its subclasses to be uniquely identified. This property is inherited from CIM_PhysicalElement.

Description
Data type: string
Access type: Read-only

Textual description of the object. This property is inherited from CIM_ManagedSystemElement.

FormFactor
Data type: uint16
Access type: Read-only

Implementation form factor for the chip. The following values can be specified.

HotSwappable
Data type: boolean
Access type: Read-only

If TRUE, the package can be hot-swapped. A physical package can be hot-swapped if the element can be replaced by a physically different (but equivalent) one while the containing package is turned on. For example, a disk-drive package inserted using SCA connectors is removable and can be hot-swapped. All packages that can be hot-swapped are inherently removable and replaceable. This property is inherited from CIM_PhysicalComponent.

InstallDate
Data type: datetime
Access type: Read-only

Date and time when the object was installed. This property does not need a value to indicate that the object is installed. This property is inherited from CIM_ManagedSystemElement.

Manufacturer
Data type: string
Access type: Read-only

Name of the organization responsible for producing the physical element. This property is inherited from CIM_PhysicalElement.

Model
Data type: string
Access type: Read-only

Name by which the physical element is generally known. This property is inherited from CIM_PhysicalElement.

Name
Data type: string
Access type: Read-only

Label by which the object is known. When subclassed, this property can be overridden to be a key property. This property is inherited from CIM_ManagedSystemElement.

OtherIdentifyingInfo
Data type: string
Access type: Read-only

Additional data, beyond asset tag information, that can be used to identify a physical element. One example is bar-code data associated with an element that also has an asset tag. Note that if only bar-code data is available, and is unique and able to be used as an element key, this property would be NULL and the bar-code data would be used as the class key in the Tag property. This property is inherited from CIM_PhysicalElement.

PartNumber
Data type: string
Access type: Read-only

Part number assigned by the organization that produces or manufactures the physical element. This property is inherited from CIM_PhysicalElement.

PoweredOn
Data type: boolean
Access type: Read-only

If TRUE, the physical element is powered on. If FALSE, the element is powered off. This property is inherited from CIM_PhysicalElement.

Removable
Data type: boolean
Access type: Read-only

If TRUE, this element 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 packaging. A package is considered removable even if the power must be "off" to perform the removal. If the power can be "on" and the package removed, then the element is removable and can be hot-swapped. For example, an extra battery in a laptop is removable, as is a disk-drive package inserted using SCA connectors; however, the latter can be hot-swapped. A laptop's display is not removable, nor is a nonredundant power supply. Removing these components impacts the function of the overall packaging or is impossible due to the tight integration of the package. This property is inherited from CIM_PhysicalComponent.

Replaceable
Data type: boolean
Access type: Read-only

If TRUE, it is possible to replace (field replaceable unit (FRU) or upgrade) the element with a physically different one. For example, some computer systems allow the main processor chip to be upgraded to one of a higher clock rating. In this case, the processor is said to be replaceable. Another example is a power-supply package mounted on sliding rails. All removable packages are inherently replaceable. This property is inherited from CIM_PhysicalComponent.

SerialNumber
Data type: string
Access type: Read-only

Manufacturer-allocated number used to identify the physical element. This property is inherited from CIM_PhysicalElement.

SKU
Data type: string
Access type: Read-only

Stock-keeping unit number for the physical element. This property is inherited from CIM_PhysicalElement.

Status
Data type: string
Access type: Read-only

String that indicates the current status of the object. Operational and non-operational status can be defined. Operational status can include "OK", "Degraded", and "Pred Fail". "Pred Fail" indicates that an element is functioning properly, but is predicting a failure (for example, a SMART-enabled hard disk drive).

Non-operational status can include "Error", "Starting", "Stopping", and "Service". "Service" can apply during disk mirror-resilvering, reloading a user permissions list, or other administrative work. Not all such work is online, but the managed element is neither "OK" nor in one of the other states. This property is inherited from CIM_ManagedSystemElement.

Values include the following:

"OK"
"Error"
"Degraded"
"Unknown"
"Pred Fail"
"Starting"
"Stopping"
"Service"
"Stressed"
"NonRecover"
"No Contact"
"Lost Comm"
Tag
Data type: string
Access type: Read-only

Uniquely identifies the physical element and serves as the element's key. This property can contain information such as asset tag or serial number data. The key for the CIM_PhysicalElement class is placed very high in the object hierarchy to independently identify the hardware/entity, regardless of physical placement in (or on) cabinets, adapters, and so on. For example, a removable component that can be hot-swapped can be taken from its containing (scoping) package and be temporarily unused. The object still continues to exist and can even be inserted into a different scoping container. The key for a physical element is an arbitrary string that is defined independently of placement or location-oriented hierarchy. This property is inherited from CIM_PhysicalElement.

Version
Data type: string
Access type: Read-only

Version of the physical element. This property is inherited from CIM_PhysicalElement.

Remarks

The CIM_Chip class is derived from CIM_PhysicalComponent.

WMI does not implement this class. For more information about classes derived from CIM_Chip, see Win32 Classes.

This documentation is derived from the CIM class descriptions published by the DMTF. Microsoft may have made changes to correct minor errors, conform to Microsoft SDK documentation standards, or provide more information.
