If a card is present in the slot and securely connected, the next step is to check the IR system administration settings for the card.
To check administration settings:
Configuration settings should match the type of card installed. VoIP cards should be enabled.
See Checking NMS card configuration for useful commands related to NMS cards.
Note:
If there are problems with licensing, there may be no usable channels on the card, and the card will not be found when the display card command is run.
If RTUs are not an issue, and the card is still not in service, you may be able to bring it back into service by removing and restoring it. See Removing and restoring cards for more information.
