Pick up the power supply with both hands and align the power supply with the guide rails. Slide the power supply forward on the guide rails to seat it in the I/O board connectors. 5. Insert and alternately tighten the two power supply jack screws, as shown in Figure 4-44 on the previous page. Take care to align the rear face of the power supply to the rear wall of the mainframe chassis so that the jack screws will mate properly. Continue tightening until the screws stop. 6. Secure the bus bars to the system board with either the four bus bar thumbscrews on the J5000 workstation, or the five bus bar thumbscrews on the J7000. Figure 4-46 shows these thumbscrews on the J5000 workstation. NOTE Failure to sufficiently tighten the bus bar thumbscrews will cause the power supply to not activate. Figure 4-46.
