Power unit: Configuration not supported

What does 230020 mean?

This fault signifies that the requested configuration for the power unit is not supported by its hardware or firmware. Possible causes include requesting unsupported autonomous operation, an impermissible DRIVE-CLiQ timing, detection of an incompatible PM260 PS-ASIC version, or an incompatible combination of power unit and Control Unit/Adapter. Initialization failure due to premature Control Unit withdrawal can also trigger this. Operating with an unsupported configuration can lead to system instability, malfunction, or prevent the drive from starting altogether.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If an incompatible PM260 with PS-ASIC version 2 is detected (fault cause = 2), replace the power unit with a PM260 featuring PS-ASIC version 3 or higher.

2. 4

   If initialization failed (fault cause = 3), ensure the Control Unit is properly seated and powered up before or during power-up, avoiding premature withdrawal.

3. 5

   If the combination of power unit and Control Unit/Adapter is unsupported (fault cause = 4), verify the compatibility matrix and replace components as necessary to achieve a supported configuration.
