 # Troubleshoot BMM provisioning in Azure Operator Nexus cluster
 
-As part of cluster deploy action, bare metal machines (BMM) are provisioned with required roles to participate in the cluster. This document supports troubleshooting for common provisioning issues using Azure CLI, Azure portal, and the server baseboard management controller (BMC). For the Azure Operator Nexus platform, the underlying server hardware uses integrated Dell remote access controller (iDRAC) as the BMC.
+As part of cluster deploy action, bare metal machines (BMM) are provisioned with required roles to participate in the cluster. This document supports troubleshooting for common provisioning issues using Azure CLI, Azure portal, and the server baseboard management controller (BMC). For the Azure Operator Nexus platform, the underlying server hardware uses integrated Dell remote access controller (iDRAC) as the BMC. Provisioning uses the Preboot eXecution Environment (PXE) interface to load the Opearating System (OS) on the BMM.
