Installation

Note 2. Host system should ground P4,P5, and P6. Failure to do so may cause improper drive operation.

The following points should be noted:

All pins are in a single row, with a 1.27 mm (.050”) pitch.

•The comments on the mating sequence apply to the case of backplane 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 3.3 V, then all V33 pins must be terminated. Otherwise, it is optional to terminate any of the V33 pins. If a device uses 5.0 V, then all V5 pins must be terminated.

Otherwise, it is optional to terminate any of the V5 pins.

•If a device uses 12.0 V, then all V12 pins must be terminated. Otherwise, it is optional to terminate any of the V12 pins.
