Unknown power unit fault

What does 5698 mean?

An unidentified logical fault has occurred within the power unit. This suggests a deep internal problem with the power unit's control or processing, possibly due to corrupted firmware, a hardware malfunction, or an unexpected state. Unresolved, this prevents the drive from operating reliably and requires expert attention.
