PXE is the only provisioning method supported for Cisco UCS Manager. You can use the network bootstrap program, and, Optionally, custom properties to initiate WIM, SCCM, or Linux Kickstart provisioning. You can also use custom properties to call your own PowerShell scripts. Linux Kickstart provisioning does not require custom properties.

You can use these properties for calling custom PowerShell scripts.

Custom Properties for Calling Custom PowerShell Scripts

Custom Property



Specifies a custom EPI PowerShell script to run on the machine before it is booted using the PXE network boot program. The value is the name assigned to the script when it is uploaded to the model manager.


Specifies the name of an EPI PowerShell script installed in the vCloud Automation Center Model Manager, to run on the machine after it is provisioned. The value is the name assigned to the script when it is uploaded to the Model Manager.

You can use these properties for PXE and SCCM provisioning.
