Description: This table is used to group redundant cards and provide a mechanism to indicate which card, if any, is preferred to be active.

A weight is assigned to each card to indicate a preference for which card should be active. In the absence of any preference (e.g., weights for all cards are equal), then the card with the lowest shelf/slot number will become active.

Notes: (1) A row for this table cannot exist without a corresponding entry in the zhoneSysCardSoftwareConfigTable. Thus, a row-create cannot occur on the this table until a corresponding row-create is performed on the zhoneSysCardSoftwareConfigTable. When a row-delete is performed on the zhoneSysCardSoftwareConfigTable, that action automatically performs a row delete on the relevant entry in this table. (2) Row deletes are disallowed on the zhoneCardRedundancy table.
