1. If the power supply slot has a cover panel on it, loosen the captive screws on the cover panel by using your fingers or 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. Taking care not to touch 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 the power
supply is fully seated and the ejector lever fits into place.
