Connecting the 733-525 Harness
If you need to connect a 733-525 Harness to a motherboard, refer to Figure 10 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 4100-0155/4120-0155 SDACT, 4100-6052 Event Reporting DACT,4100-6053Point Reporting
DACT, or a 4100-0153 / 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
