5.11.3 Connecting to 4100 Motherboards
Panels with motherboards on the left side of the expansion bays require some non-PDI connections. If you need to connect a harness to
a motherboard, refer to Figure 30 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 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 4100-6052 DACT 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.
