Figure B–4: J20 and J21 Backplane Interface Connector
An alternate connection scheme would be to build a connector to connect to the
P1 and P2 Power Supply Interface connectors. Figure B–5 shows an example of
the connector. You can assemble a mating connector using parts from the
AMPOWER Wave Crimp System (AMP catalog number 82271) with four cable
receptacles with eight signal lines. You will need to assemble the cable recep-
tacle using a housing (catalog number 765224-1), a strain relief (catalog
number 765238-1), ground contacts (catalog part number 765209-1), and power
contacts (catalog part number 765209-2).
