The information on how to work with switches is described in How to work with switches.

Before using the dialog of HCD to define a hardware configuration, you should have a plan of what your configuration should look like, and what you have to do to accomplish that. Preferably, the requirements of your configuration should be established in a configuration plan. Refer to z/OS HCD Planningz/OS HCD Planning (for a z/OS, OS/390, or MVS configuration) and z/VM CP Planning and Administration (for a z/VM configuration) for a description of what needs to be considered when this plan is prepared.
