Panels with legacy motherboards in the expansion bay require some non-PDI
connections. If you need to connect a harness to a motherboard, refer to Figure 2-6 and
follow these steps. Make sure to route the power and communication wiring on the left
side of the bay.
1. Connect one end of the 733-525 Harness to a motherboard in the CPU bay.
If the CPU bay has no additional motherboards (the usual case), connect the harness
to the P8 and P7 connectors of the CPU motherboard.
• Insert the harness connector with the blue wire into the P8 connector. Note that
the P8 connector has eight pins. Insert the harness connector on either the top
four pins or the bottom four pins, not in the middle.
• Insert the harness connector with the white wire into the P7 connector. Note that
the P7 connector has eight pins. Insert the harness connector on either the top
four pins or the bottom four pins, not in the middle.
2. Connect the other end of the harness to the leftmost motherboard in the next bay,
as described below.
• Insert the harness connector with the blue wire into the P2 connector. Note
that the P2 connector has eight pins. Insert the harness connector on either
the top four pins or the bottom four pins, not in the middle.
• Insert the harness connector with the white wire into the P3 connector. Note
that the P3 connector has eight pins. Insert the harness connector on either
the top four pins or the bottom four pins, not in the middle.

are limitations of where motherboards can be placed – see next section)
