> Fibre Connection (FICON) interface capabilities enhance the Cisco MDS 9000 Family by supporting both open systems and mainframe storage network environments. The control unit port (CUP) also is supported, which allows in-band management of the switch from FICON processors.

> Note Cisco Fabric Manager release 3.x does not support FICON management of Cisco MDS 9000 Family switches running SAN-OS release 2.(x).
