Step 7 For AC-input power supplies: On the interface processor side of the power supply, replace the cable retention clip on the AC input port by pinching the sides of the retention clip together and letting the ends of the retention clip snap outward into the holes in the jackscrews.

For DC-input power supplies: To provide strain relief for the DC-input cable, replace the nylon cable tie with a new nylon cable tie.
