What happens when the ED1 fails?

When the ED1 fails, the system is designed to automatically transfer functions to ED2 to ensure continuous operational capability. This auto transfer mechanism is crucial for maintaining system reliability and allowing the crew to continue their tasks without significant interruption. The transfer minimizes the impact of the failure by seamlessly shifting the workload from the failed unit to the backup, thus preserving critical functions and data integrity.

The other options do not accurately reflect the designed response to a failure of ED1. For example, auto-resetting or shutting down would not provide a solution to ensure ongoing operations, and sending an alert to the crew may not be as effective without immediately addressing the failure through the transfer process. This design emphasizes redundancy and reliability, ensuring that the system can perform its essential functions even in the event of component failure.
