Before proceeding to the set-up steps, verify that the correct ACLs exist on the BMC management switch. The ACLs have been added to recent deployments by the Dell Technologies Services organization, but earlier deployments may not include them.
For more information about ACLs, see the latest version of the Dell EMC Integrated System for Microsoft Azure Stack Hub Patch and Update Installation Guide.
Note: Pay particular attention to the names of the switch parameters and connections for the ACLs. These names were changed for systems that were deployed during or after the 1807 release. For details, see the .
If you need further guidance about checking the ACLs or making the appropriate changes, open a case with Dell Technologies Support.
