Table 7 summarizes the signals on the Serial ATA interface and power connectors..

1.

All pins are in a single row, with a 1.27 mm (0.050”) pitch.

2.

The comments on the mating sequence apply to the case of backplane blindmate connector only. In this 
case, the mating sequences are:

• the ground pins P4 and P12.

• the pre-charge power pins and the other ground pins.

• the signal pins and the rest of the power pins.

3.

There are three power pins for each voltage. One pin from each voltage is used for pre-charge when 
installed in a blind-mate backplane configuration.

4.

All used voltage pins (V

x

) must be terminated.
