The DAS cannot be powered on after a normal shutdown (fans not spinning, indicators not lit), and a disk loss warning appeared before shutdown. How to troubleshoot?

Applicable Models

All DAS models

This situation usually points to a power adapter failure. Check whether the indicator on the power adapter (usually green) stays lit. If the indicator is not lit, the adapter is damaged and cannot supply power. If the indicator lights up normally, the issue may be with the DAS itself.
