If the ED1 screen fails, which ED will automatically display ED1 information?

• A. ED2.
• B. ED1 reverts to ED2.
• C. ED3 takes over.
• D. No automatic display; manual control required.

Answer: (A)

When a display in the ED setup is designed with redundancy, ED2 is configured to automatically take over ED1’s data feed if ED1 fails. This failover keeps ED1’s information visible without any manual action, preserving monitoring continuity for clinicians. The system’s control logic detects the fault on ED1 and instantly redirects ED1’s information to ED2, so staff still see the same ED1 data on another screen. The other options would require manual intervention or rely on a third screen, which isn’t how the built-in failover is typically designed.
