CreationClassName

Data type: string

Access type: Read-only

Qualifiers: CIM_Key, MaxLen (256)

Name of the first concrete class that appears in the inheritance chain that is used in the creation of an instance. When used with the other key properties of the class, this property allows all instances of this class and its subclasses to be identified uniquely.

This property is inherited from CIM_PhysicalElement.

CurrentRequiredOrProduced

Data type: sint16

Access type: Read-only

Qualifiers: Units ("amps at 120 volts")

Current that is required by the chassis at 120V. If power is provided by the chassis—as in the case of an uninterruptible power supply (UPS)—this property may indicate the amperage produced (as a negative number).

This property is inherited from CIM_Chassis.

Depth

Data type: real32

Access type: Read-only

Qualifiers: Units ("inches")

Depth of the physical package—in inches.

This property is inherited from CIM_PhysicalPackage.

Description

Data type: string

Access type: Read-only

Qualifiers: DisplayName ("Description")

Description of the object.

This property is inherited from CIM_ManagedSystemElement.

HeatGeneration

Data type: uint16

Access type: Read-only

Qualifiers: Units ("BTU per hour")

Amount of heat that is generated by the chassis in BTU/hour.

This property is inherited from CIM_Chassis.

Height

Data type: real32

Access type: Read-only

Qualifiers: Units ("inches")

Height of the physical package—in inches.

This property is inherited from CIM_PhysicalPackage.

HotSwappable

Data type: boolean

Access type: Read-only

If TRUE, a physical package can be hot-swapped (if it is possible to replace the element with a physically different but equivalent one while the containing package has power applied to it). For example, a disk drive package that is 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_PhysicalPackage.

InstallDate

Data type: datetime

Access type: Read-only

Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5"), DisplayName ("Install Date")

Date and time the object was installed. This property does not require a value to indicate that the object is installed.

This property is inherited from CIM_ManagedSystemElement.

LockPresent

Data type: boolean

Access type: Read-only

If TRUE, the frame is protected with a lock.

This property is inherited from CIM_PhysicalFrame.

Manufacturer

Data type: string

Access type: Read-only

Qualifiers: MaxLen (256)

Name of the organization that produces the physical element.

This value comes from the Manufacturer member of the System Enclosure or Chassis structure in the SMBIOS information.

This property is inherited from CIM_PhysicalElement.

Model

Data type: string

Access type: Read-only

Qualifiers: MaxLen (64)

Name by which the physical element is known.

This property is inherited from CIM_PhysicalElement.

Name

Data type: string

Access type: Read-only

Qualifiers: DisplayName ("Name")

Label by which the object is known. When subclassed, the property can be overridden to be a key property.

This property is inherited from CIM_ManagedSystemElement.

NumberOfPowerCords

Data type: uint16

Access type: Read-only

Number of power cords that must be connected to the chassis for all of the components to operate.

This property is inherited from CIM_Chassis.

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 that is associated with an element that also has an asset tag. Be aware that if only bar code data is available and is unique or able to be used as an element key, this property would be NULL and the bar code data used as the class key, in the tag property.

This property is inherited from CIM_PhysicalElement.

PartNumber

Data type: string

Access type: Read-only

Qualifiers: MaxLen (256)

Part number that is assigned by the organization that produces or manufacturing 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.

This property is inherited from CIM_PhysicalElement.

Removable

Data type: boolean

Access type: Read-only

If TRUE, a physical package 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 packaging). A package can still be removable if the power must be "OFF" to perform the removal. If the package can be removed while the power is ON, 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 that is inserted using Server Configuration Application (SCA) connectors. However, the latter can be hot-swapped. A laptop display is not removable, nor is a nonredundant power supply. Removing these components would affect the function of the overall packaging or is impossible because of the tight integration of the package.

This property is inherited from CIM_PhysicalPackage.

Replaceable

Data type: boolean

Access type: Read-only

If TRUE, this physical media component can be replaced 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_PhysicalPackage.

SecurityBreach

Data type: uint16

Access type: Read-only

Qualifiers: MappingStrings ("MIF.DMTF|Physical Container Global Table|002.12"), ModelCorrespondence ("CIM_PhysicalFrame.BreachDescription")

This value comes from the Asset Tag Number member of the System Enclosure or Chassis structure in the SMBIOS information.

Status

Data type: string

Access type: Read-only

Qualifiers: MaxLen (10), DisplayName ("Status")

Current status of the object. Various operational and nonoperational statuses can be defined. Operational statuses include: "OK", "Degraded", and "Pred Fail" (an element, such as a SMART-enabled hard disk drive, may be functioning properly but predicting a failure in the near future). Nonoperational statuses include: "Error", "Starting", "Stopping", and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is online, yet 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 ("OK")

Error ("Error")

Degraded ("Degraded")
