Page 3 version 1. 0 Hitachi Global Storage Technologies Interface connector The figure below shows the physical pin location All pins are in a single row, with a 127 mm (0. 050") pitch. The comments on the mating sequence in Table in the section 7. 3 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.
