To modify the card type already provisioned for a specific slot, you must shutdown existing port configurations and shutdown and remove all MDA or XMA configurations.
You must reset the IOM after changing the MDA type from MS-ISA to any other MDA type.
Use the following CLI syntax to modify a card type already provisioned for a specific slot:
config> port
port-id
— [no] shutdown
config> card slot-number
— mda mda-number
— [no] mda-type mda-type
— [no] shutdown
