text: After the wizard completes, your system consists only of the control enclosure that includes 
  the node canister that you used to initialize the system. If you have other control and 
  expansion enclosures, you must add them to complete system setup. 
  
  For more information about how to add a control enclosure, see 4.3.2, “Adding a control 
  enclosure” on page 107. For more information about how to add an expansion enclosure, see 
  Chapter 5, “Graphical user interface” on page 131. 
  
  After you add the enclosures or if you have no expansion enclosures to install, the system 
  setup process is complete. 
  
  Completing system setup means that all mandatory steps of the initial configuration are 
  completed and you can start configuring your storage. Optionally, you can configure other 
  features, such as user authentication, secure communications, and local port masking. 
  
  **4.3.2 Adding a control enclosure**
  
  This procedure is the same whether you are configuring the system for the first time or 
  expanding it later. 
  
  Before beginning this process, ensure that the new control enclosure is correctly installed and 
  cabled to the existing system. Ensure that the Ethernet and Fibre Channel connectivity is 
  correctly configured and that the enclosure is powered on.
