If you need to connect a 733-525 Harness to a motherboard, refer to Figure 9 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 harness to a motherboard in an adjacent bay.
If the adjacent bay is a CPU bay with no additional motherboards, 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.
If the adjacent bay is an expansion bay or a CPU bay with additional motherboards, connect
the harness to the P2 and P3 connectors of the motherboard installed in the leftmost slot. (If a
4100/4120-0155 SDACT, 4100-6052 Event Reporting DACT, 4100-6053 Point Reporting
DACT, or a 4100/4120-0153 CCDACT occupies the leftmost slot, connect the harness to the
motherboard in the second slot from the left.) Connect the harness as follows:
• 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.
2. Connect the other end of the harness to the leftmost motherboard in the next bay, as
described below. Make sure to route the wiring on the left side of the bay.
• 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.
