The following shows a procedure of performing fail-back after failure recovery if node switching occurs.

1) Make recovery for a node on which a failure has occurred.

If switching has occurred due to panic or hang-up, reboot the node that has panicked or hanged up.
If switching has occurred due to a line failure, restore the line to a normal status (perform necessary work such as reconnecting a cable, powering on a HUB again, and replacing a faulty HUB).

2) Restore the original operation status.

Restore the original operation status by performing fail-back operation for userApplication.
