6. Update  Channel path IDs  to  E6  (channel path ID E6 is the CHPID we defined in the  previous example) to define the Processor / CU connection (see Figure 13-62). Press  Enter. 7. HCD now shows the Modify Device Parameters panel where you can override the UA  numbers. For IQD definitions, the Unit address often starts at  00 .
