You might want to connect the OSC Control Unit definition to multiple CPCs even though the  physical OSC is still unique to any one CPC. Also, you might want to span the OSC over  multiple CSSs within a CPC. The following are considerations for connecting an OSC CHPID to an OSC Control Unit and  its 3270-X devices: To define OSC CHPID connections to an OSC Control Unit, complete these steps: HCD now shows the Select Processor / CU panel. This panel is where the connection is  now made between the OSC CHPID (C6) and the Control Unit (1C60). Chapter 13. Adding network devices  291 GLYPH<SM590000> How many OSCs are required to provide a primary and secondary/backup network  connection. GLYPH<SM590000> The example will be connecting to a predefined OSC Control Unit (1C60) and 3270-X  devices 0700-070F. 1. From the main HCD panel, select option 1.4. Control units . 2. Scroll through the Control Unit List until you find the control unit you want to connect to or  in the command line enter  L 1C60 . In our example, we use 1C60. 3. Enter c next to the Control Unit definition, and press  Enter . 4. Make any changes to the Control Unit definition that you want (Figure 13-4), and press  Enter . +----------------- Change Control Unit Definition ------------------+ | | | | | Specify or revise the following values. | | | | Control unit number . . . .  1C60 + | | | | Control unit type . . . . .
