There are some customer scenarios, where the gateway boards and OpenScape 4000 Assistant are in separated IP-networks (no routing between these two networks) and therefore backup and restore functionality via OpenScape 4000 Assistant is not possible. In these cases the WBM configuration data/certificates can be saved in local flash of the board. Then backup and restore is still possible when connectivity to OpenScape 4000 Assistant backup server is missing or the backup server cannot be reached.
