+If you have power connected to your nodes and are still getting NOT REGISTERED for your state, check your networking connections or managed switch configurations.  NOT REGISTERED means that your CMC service cannot communicate with your client nodes.

+==== Imaging ====
+
+Since your client nodes did not come with images preloaded on them, you will have to image your nodes for the first time.  This can be done with the '''omf load''' command.
