Page 3 version 1. 0 Hitachi Global Storage Technologies Interface connector The figure below shows the physical pin location. This connector is identical for 2. 5" and 3. 5" SATA hard disk drives, therefore the host side cabling is suitable for both form factors. All pins are in a single row, with a 127 mm (0. 050") pitch. The comments on the mating sequence in Table in section 7. 3 of the Product Specification Manual apply to the case of back-plane blind-mate connector only. In this case, the mating sequences are:(1) the ground pins P4 and P12;(2) the pre-charge power pins and the other ground pins; and (3) the signal pins and the rest of the power pins. There are three power pins for each voltage. One pin from each voltage is used for pre-charge in the backplane blind-mate situation. If a device uses 3. 3V, then all V33 pins must be terminated. Otherwise, it is optional to terminate any of the V33 pins If a device uses 5. 0V, then all V5 pins must be terminated. Otherwise, it is optional to terminate any of the V5 pins If a device uses 12. 0V, then all V12 pins must be terminated. Otherwise, it is optional to terminate any of the V12 pins.
