the screwdriver. Hold the screws and gently pull the cover panel outward to remove the cover panel. Save the cover
panel for later use.
2. Without touching the power supply pins, leads, or solder connections, remove the power supply from the bag.
3. Using both hands, place the power supply in the power supply slot on the rear panel of the switch and slide it in until
it is fully seated and the ejector lever fits into place.
