Applies to
Aquilion 16 (TSX-101A) — Console (Operation) volume, source 2D201-079, §6.2 ("Host PC Unit (For PX74-07959 GR-1 and GR-2)"), p.45-46. Source does not further define what "GR-1"/"GR-2" stand for beyond this section-title designation — preserved verbatim, not interpreted. This procedure is specific to the -07959-generation CPU BOX; a newer CPU BOX generation, -08766, is covered by a separate procedure (see toshiba-ct-aquilion16-console-host-pc-08766-remove, Related). Applies equally to both host PC units mounted in the CPU BOX cabinet: the acquisition host PC unit (PC1) and the image-processing host PC unit (PC2).
