This topic describes the symbolic FRU for the single-phase DC supply unit
(DSU).
About this task
The part number cannot be determined from VPD by the reporting system (FSP or LPAR). If
there is no serviceable event from the partner system that shows a FRU part number at the same
location as this symbolic FRU, refer to the Parts Catalog for the part number of the DC
supply unit (DSU).
