Schematic PDF of 1.50 MB named only z60, with no brand, board number or revision given, so the exact device cannot be identified from the name alone. Open the file and read the title block or ODM project code on its pages to determine which product it covers. Once matched, a schematic of this kind is used for tracing power rails, finding the source of shorts, following power sequencing signals and checking connector pinouts. Always verify the board number and revision on the PCB against the drawing before relying on component values.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @smschematics. Enginerys does not host this file.
