To connect AC power to a QFX5220-128C:
1. Attach the grounding strap to your bare wrist and to a site ESD point.
2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure.
3. Locate the power cords shipped with the switch; the cords have plugs appropriate for your geographical
location.
For each power supply:
a. Ensure the loop on the power cord retainer is open and there is enough space to insert the power
cord coupler into the inlet. If the loop is closed, press the small tab on the retainer to loosen the
loop.
b. Thread the power cord coupler through the power cord retainer loop.
c. Insert the power cord coupler firmly into the AC inlet on the power supply faceplate.
d. Slide the power cord retainer loop towards the power supply until it is snug against the base of the
coupler.
e. Press the tab on the loop and draw out the loop to enclose the power cord. See Figure 48 on page 130 .
