Example 2

1. The module in Slot 3 fails.

   The module in Slot 2 serves as the backup, because slot 2 is the lowest priority backup available.

2. The module in Slot 1 fails.

   The module in Slot 2 drops the content for slot 3 (because slot 1 is higher priority than slot 3) and serves as slot 1's backup.

3. The module in Slot 2 fails.

No backups are available. All slots have failed and are out of service.
