CIM_Slot

Subclass of CIM_PhysicalConnector

The Slot class represents Connectors into which Packages are inserted. For example, a PhysicalPackage that is a DiskDrive may be inserted into an SCA ‘Slot’. As another example, a Card (subclass of PhysicalPackage) may be inserted into a 16-, 32-, or 64-bit expansion ‘Slot’ on a HostingBoard. PCI or PCMCIA Type III Slots are examples of the latter.

Local properties

boolean Powered

A boolean indicating whether the Slot is currently powered (TRUE) or not (FALSE).

string PurposeDescription

A free-form string describing that this Slot is physically unique and may hold special types of hardware. This property only has meaning when the corresponding boolean property, SpecialPurpose, is set to TRUE.

boolean SpecialPurpose

Boolean indicating that this Slot is physically unique and may hold special types of hardware, e.g. a graphics processor slot. If set to TRUE, then the property, Special PurposeDescription (a string), should specify the nature of the uniqueness or purpose of the Slot.

boolean BifurcationCapability

This value indicates if the slot is capable of being bifurcated. True meaning the slot is capable, False meaning it is not capable.

real32 HeightAllowed

Maximum height of an adapter Card that can be inserted into the Slot, in inches.

uint16 MaxDataWidth

Maximum bus width of adapter Cards that can be inserted into this Slot, in bits. If the value is ‘unknown’, enter 0. If the value is other than 8, 16, 32, 64 or 128, enter 1.

boolean OpenSwitch

A boolean indicating whether the switch state of the Slot is currently open (TRUE) or closed (FALSE). This switch state determines whether the contents of the Slot can be hot-plugged.

uint16[] ConnectorType

Deprecated! An array of integers defining the type of PhysicalConnector. An array is specified to allow the description of ‘combinations’ of Connector information. For example, one array entry could specify RS-232 (value=25), another DB-25 (value=23) and a third entry define the Connector as “Male” (value=2).

This single property is being deprecated in lieu of using separate properties to describe the various aspects of the connector. The separation allows for a more generic means of describing the connectors. Obsolete connectors were intentionally removed from the new list.

Value 123 (CXL Flexbus 1.0) is deprecated. Use the CXLSupport property to indicate that a PCI Express slot is CXL-capable.

string[] VendorCompatibilityStrings

An array of strings that identify the components that are compatible and can be inserted in a slot. This allows vendors to provide clues to the system administrators by providing sufficient information to request the appropriate hardware that can populate the slot. In order to ensure uniqueness within the NameSpace, each value defined by the vendor for use in the VendorCompatibilityStrings property SHOULD be constructed using the following ‘preferred’ algorithm:

<OrgID>:<LocalID>

Where <OrgID> and <LocalID> are separated by a colon ‘:’, and where <OrgID> MUST include a copyrighted, trademarked or otherwise unique name that is owned by the business entity creating/defining the InstanceID, or is a registered ID that is assigned to the business entity by a recognized global authority (This is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness <OrgID> MUST NOT contain a colon (‘:’). When using this algorithm, the first colon to appear in InstanceID MUST appear between <OrgID> and <LocalID>.

<LocalID> is chosen by the business entity and SHOULD not be re-used to identify different underlying (real-world) elements.

boolean SupportsHotPlug

Boolean indicating whether the Slot supports hot-plug of adapter Cards.

uint16[] VppMixedVoltageSupport

An array of enumerated integers indicating the Vpp voltage supported by this Slot.

boolean PoweredOn

Boolean that indicates whether the PhysicalElement is powered on (TRUE) or is currently off (FALSE).

uint32 ThermalRating

Maximum thermal dissipation of the Slot in milliwatts.

uint16[] VccMixedVoltageSupport

An array of enumerated integers indicating the Vcc voltage supported by this Slot.

real32 LengthAllowed

Maximum length of an adapter Card that can be inserted into the Slot, in inches.

uint16 MaxLinkWidth

Maximum link width of a switching bus type, such as Infiniband and PCI Express. The width is expressed in number of communication lines, or lanes, between port and devices. This property dictates the maximum link width, in lanes, of adapter Cards that can be inserted into this Slot. If the value is ‘unknown’, enter 0.

uint16 Number

The Number property indicates the physical slot number, which can be used as an index into a system slot table, whether or not that slot is physically occupied.
