Deleting a Card

In order to delete the card type provisioned for a specific slot, you must shutdown existing port
configurations and shutdown and remove all MDA or CMA configurations. After removing MDA
configurations, you may 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:

Use the following CLI syntax to delete a card provisioned for a specific slot:

CLI Syntax:

config> port

port-id

shutdown

CLI Syntax:

config> card

slot-number

card-type

card-type

mcm

mcm-number

no mcm-type

no shutdown

mda

Deleting Port Parameters

Use the following CLI syntax to delete a port provisioned for a specific card:

CLI Syntax:

config>port
