The Win32_SystemSlot WMI class represents physical connection points including ports, motherboard slots and peripherals, and proprietary connection points.
Methods
Win32_SystemSlot has no methods.
Properties
Win32_SystemSlot returns 35 properties:
'BusNumber','Caption','ConnectorPinout','ConnectorType','CreationClassName',
'CurrentUsage','Description','DeviceNumber','FunctionNumber','HeightAllowed','InstallDate',
'LengthAllowed','Manufacturer','MaxDataWidth','Model','Name','Number','OtherIdentifyingInfo',
'PartNumber','PMESignal','PoweredOn','PurposeDescription','SegmentGroupNumber','SerialNumber',
'Shared','SKU','SlotDesignation','SpecialPurpose','Status','SupportsHotPlug','Tag',
'ThermalRating','VccMixedVoltageSupport','Version','VppMixedVoltageSupport'
Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:
Get-CimInstance -ClassName Win32_SystemSlot -Property *
Most WMI classes return one or more instances.
When
Get-CimInstancereturns no result, then apparently no instances of class Win32_SystemSlot exist. This is normal behavior.Either the class is not implemented on your system (may be deprecated or due to missing drivers, i.e. CIM_VideoControllerResolution), or there are simply no physical representations of this class currently available (i.e. Win32_TapeDrive).
BusNumber
SMBIOS Bus Number.
This value comes from the Bus Number member of the System Slots structure in the SMBIOS information.

Get-CimInstance -ClassName Win32_SystemSlot | Select-Object -Property Tag, BusNumber
Caption
Short description of an objectâa one-line string.
Get-CimInstance -ClassName Win32_SystemSlot | Select-Object -Property Tag, Caption
ConnectorPinout
Free-form string that describes the pin configuration and signal usage of a physical connector.
Get-CimInstance -ClassName Win32_SystemSlot | Select-Object -Property Tag, ConnectorPinout
ConnectorType
Array of physical attributes of the connector that this slot uses.
This value comes from the Slot Type member of the System Slots structure in the SMBIOS information.
ConnectorType returns a numeric value. To translate it into a meaningful text, use any of the following approaches:

CurrentUsage
Status of system slot use.
This value comes from the Current Usage member of the System Slots structure in the SMBIOS information.
CurrentUsage returns a numeric value. To translate it into a meaningful text, use any of the following approaches:
Use a PowerShell Hashtable
$CurrentUsage_map = @{
0 = 'Reserved'
1 = 'Other'
2 = 'Unknown'
3 = 'Available'
4 = 'In use'
}
Use a switch statement
switch([int]$value)

}
Use Enum structure

ThermalRating
Maximum thermal dissipation of the slot in milliwatts.
Get-CimInstance -ClassName Win32_SystemSlot | Select-Object -Property Tag, ThermalRating
VccMixedVoltageSupport
Array of enumerated integers indicating the Vcc voltage supported by this slot.
This value comes from the Slot Characteristics 1 member of the System Slots structure in the SMBIOS information.
VccMixedVoltageSupport returns a numeric value. To translate it into a meaningful text, use any of the following approaches:
Use a PowerShell Hashtable
$VccMixedVoltageSupport_map = @{
0 = 'Unknown'
1 = 'Other'
2 = '3.3V'
3 = '5V'
}
Use a switch statement
switch([int]$value)
{
0 {'Unknown'}
1 {'Other'}
2 {'3.3V'}
3 {'5V'}
default {"$value"}
}
Use Enum structure
Enum EnumVccMixedVoltageSupport
{
Unknown = 0
Other = 1
_33V = 2
_5V = 3
}

Selecting Properties
To select only some properties, pipe the results to Select-Object -Property a,b,c with a comma-separated list of the properties you require. Wildcards are permitted.
Get-CimInstance always returns all properties but only retrieves the ones that you specify. All other properties are empty but still present. That’s why you need to pipe the results into Select-Object if you want to limit the visible properties, i.e. for reporting.
Selecting Properties
The code below lists all available properties. Remove the ones you do not need:
$properties = 'BusNumber',
'Caption',
'ConnectorPinout',
'ConnectorType',
'CreationClassName',
'CurrentUsage',
'Description',
'DeviceNumber',
'FunctionNumber',
'HeightAllowed',
'InstallDate',
'LengthAllowed',
'Manufacturer',
'MaxDataWidth',
'Model',
'Name',
'Number',
'OtherIdentifyingInfo',
'PartNumber',
'PMESignal',
'PoweredOn',
'PurposeDescription',
'SegmentGroupNumber',
'SerialNumber',
'Shared',
'SKU',
'SlotDesignation',
'SpecialPurpose',
'Status',
'SupportsHotPlug',
'Tag',
'ThermalRating',
'VccMixedVoltageSupport',
'Version',
'VppMixedVoltageSupport'
Get-CimInstance -ClassName Win32_SystemSlot | Select-Object -Property $properties
Limiting Network Bandwidth
If you work remotely, it makes sense to limit network bandwidth by filtering the properties on the server side, too:
Get-CimInstance -Class Win32_SystemSlot -Property $property |
Select-Object -Property $property
Selecting Instances
To select some instances, use Get-CimInstance and a WMI Query. The wildcard character in WMI Queries is % (and not “*”).
The parameter -Filter runs a simple query.
Listing all instances where the property Caption starts with “A”
Get-CimInstance -Class Win32_SystemSlot -Filter 'Caption LIKE "a%"'
Using a WQL Query
The parameter -Query uses a query similar to SQL and combines the parameters -Filter and -Property. This returns all instances where the property Caption starts with “A”, and returns the properties specified:
Get-CimInstance -Query "SELECT SKU, ConnectorType, LengthAllowed, Model FROM Win32_SystemSlot WHERE Caption LIKE 'a%'"
Any property you did not specify is still present but empty. You might need to use
Select-Objectto remove all unwanted properties:Get-CimInstance -Query "SELECT SKU, ConnectorType, LengthAllowed, Model FROM Win32_SystemSlot WHERE Caption LIKE 'a%'" | Select-Object -Property SKU, ConnectorType, LengthAllowed, Model
Accessing Remote Computers
To access remote systems, you need to have proper permissions. User the parameter -ComputerName to access one or more remote systems.
Authenticating as Current User
# one or more computer names or IP addresses:
$list = 'server1', 'server2'
# authenticate with your current identity:
$result = Get-CimInstance -ClassName Win32_SystemSlot -ComputerName $list
$result
Authenticating as Different User
Use a CIMSession object to authenticate with a new identity:
# one or more computer names or IP addresses:
$list = 'server1', 'server2'
# authenticate with a different identity:
$cred = Get-Credential -Message 'Authenticate to retrieve WMI information:'
$session = New-CimSession -ComputerName $list -Credential $cred
$result = Get-CimInstance Win32_SystemSlot -CimSession $session
# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session
$result
