AWS ベースの Nexus Dashboard の展開では、ノードが何らかの理由で RMA または交換が必要な場合、新しい交換用ノードをAWS に展開する必要があります。
オンプレミスの物理 Nexus Dashboard（pND）およびリモート対応 Nexus Dashboard（vND）の展開で使用可能な工場出荷時の状態へのリセットとノードの復元オプションは、AWS ベースのノードではサポートされていません。したがって、影響を受けたノードをその場所で回復することはできず、新しいノードとして再展開する必要があります。
元の 3 ノード CloudFormation（CFT）テンプレートを使用して個々のノードを置き換えないでください。単一ノードの交換の場合は、以下に示す専用の単一ノード CFT テンプレートを使用して新しいノードを展開します。
