## Deploy Omnia Control Plane
Before you configure the Dell EMC PowerSwitches, you must complete the deployment of Omnia control plane. Go to Step 8 in the [Steps to install the Omnia Control Plane](../../INSTALL_OMNIA_CONTROL_PLANE.md#steps-to-deploy-the-omnia-control-plane) file to run the `ansible-playbook control_plane.yml` file.
