Removing and Installing Summit 300-48 Power Supplies

The Summit 300-48 comes with a minimum of one power supply pre-installed at the factory. Follow the
instructions in this section for removing and installing power supplies. Switches with one power supply
have a metal cover plate in place of the second supply. If you install a second power supply, be sure to
retain the cover plate in case you later decide to use only one supply.
