Ensure that your power source(s) are powered off.
Remove the nut and star washer from the ground stud(s) on the back of the firewall.

Remove the connector cover from the power supply. Connect the positive and negative cable ends to the respective polarity slots in the power supply, then re-install the connector cover. Repeat this for each power supply.
Connect the opposite end of the positive and negative cables to a 60A circuit breaker, then secure the power cords to the power inlets using the velcro straps. Repeat this for the second power supply, ensuring that each power supply is connected to its own 60A power circuit breaker. This ensures power redundancy and allows for planned electrical circuit maintenance.
After each DC cable is securely connected, turn on the power source and the appliance will power on.

Before powering on the firewall, ensure that you have connected your Ethernet cables in accordance to the mode you wish to boot the firewall in (standard mode or Zero Touch Provisioning mode) as specified in Set Up a Connection to the Firewall.
