Modifying a Card Type
In order to modify the card type already provisioned for a specific slot, you must shutdown
existing port configurations and shutdown and remove all MDA or CMA configurations. For 7750
SR-c12/c4 systems, after removing MDA configurations, shutdown and remove the MCM from
service before modifying the card.
Note: CMAs do not require an MCM, therefore, if removing a CMA-type MDA from service, it is
not required to shutdown and remove an MCM before modifying the card.
Note: 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:
CLI Syntax: config> port port-id
[no] shutdown
CLI Syntax: config> card slot-number
mda mda-number
[no] mda-type mda-type
[no] shutdown
CLI Syntax: config> card slot-number
shutdown
[no] mcm mcm-number
no mcm-type mcm-type
shutdown
