How does the EC312 handle sudden power outages?

The EC312 features a built-in Supercapacitor for power loss protection:
      Hold-up Time: It can maintain system operation for 20–30 seconds after external power is lost.
      Alarming: It automatically sends a UDP broadcast notification to alert the network of the power failure.
      Data Integrity: It performs an active safe shutdown to prevent file system corruption.
