| Related official records with the same scored hardware | Not listed | The official specification table also lists TS-432pxu-rp as a related model. Scored hardware figures on the official pages we used are the same; the official difference is a redundant power supply and the published size or weight that goes with it. We keep one product page for this official hardware set so the RP and non-RP listings are not given separate nearly identical pages. | info |
