Make sure that the Power Supply Unit and Data Flow Controller are connected correctly.
If the PWR indicator on the Power Supply Unit does not light up even after taking the above actions, replace the Power Supply Unit.

Perform initialization (factory reset) to restore the factory settings.
If the RUN indicator still does not light up, the Data Flow Controller may be faulty. Replace it.
