NOTE: Replace the power supply
•
Position the power supply over the chassis, then insert its side hooks into
the holes on the back of the chassis. See step 1 in the figure below.
•
Carefully swing the power supply inward, making sure that the arc on top
of the power supply matches the curved railing on top of the system unit.
See step 2 in the figure below.
•
Push the power supply all the way in until you hear a click that locks it into
the system unit.
•
Arrange the power cables and secure them with the cable tie to prevent
them from touching the system board components.
