Figure 3-5 Sample IOCP coding for cascaded FICON Directors configuration
During installation of the FICON Director, a valid switch address has to be assigned. The
Director has a defined switch address, which can be altered to match the customer
requirements.
Figure 3-6 shows the system configuration panel where the switch address (Director Domain
ID) can be altered. This value has to be entered as a decimal value, and is then calculated to
hexadecimal value by the firmware.
