   The Switch List (left part), Figure 73, lists one switch control unit and device. If there is more than one switch control unit and device, the list entry gets an indication ('>'). With the F20=Right key, you can scroll to the right part of the Switch List. Up to five switch control units and devices can be shown. If there are more, an indication is given for the corresponding entry ('Yes' in column 'More?' on the right part of the Switch List). These additional switch control units and devices can be viewed, for example, on the Port List for port FE.

   HCD allows you to specify the port range of a switch to be set to installed, if more ports are to be used than the minimum range. Specify the first and last port of the range you want to use. If you do not specify values for the Installed port range field, the hardware status of the minimum range of supported ports is set to installed.

   In order to allow consistency checks for the configuration, when adding a new switch, you can optionally define a switch address for a FICON switch.

   You can also specify control unit numbers and device numbers for the switch.

   On the Add Switch panel you can initially define up to five switch control units and devices for the switch. To define more than five switch control units and devices, or to add additional switch control units and devices later, you must use the control unit and device definition dialogs.

   If you specify switch control units that do not yet exist, they are automatically added as new objects to the IODF, and are connected to the switch through the switch control unit port. In this case, you need to specify new switch devices. The switch devices are also automatically added as new objects to the IODF and connected to the switch through the switch control units. However, to complete the configuration path, you must attach the switch control units and switch devices to a processor, and then you can assign the switch devices to an operating system.

   If the switch control units already exist, they are automatically connected to the control unit port on the newly defined switch. In this case, you do not need to specify switch devices. If you do, the switch devices must already exist and be attached to the designated switch control units.

   Specified serial numbers or descriptions are also copied to the switch control units and switch device definitions.

3. After you press the Enter key, HCD displays the updated Switch List.
   • Connect the switch control units to the processor (which also connects the switch devices to the processor). To specify additional parameters use the Change action on the Control Unit List. For details, see Defining processor attachment data.
   • Connect the switch devices to the operating system. Use the Change action on the I/O Device List. For details, see Changing devices.
