Network Failover Viprion2400

Hi, My Issue if I disable bridge aggregation for Active Node 1, it should fail over to node 2. Because in bridge aggregation i have combined fc1.2 and Fc.1.1 on Viprion System. and I am disabling these link. Idealy i am disconnection from Network Node 1., so in this case Node 2 will be active, and node 1 should go in standby mode, but that is not happening. After disabling Bridge Aggregation for node1 it is in Active mode but disconnected, and Node2 is also in active mode. which one is forwarding traffic to client. I think this should not be an issue, becasue Node1 is isolated from network, Pls corrrect.
