  1. Remove the nut and star washer from the ground stud on the back of the firewall.
  2. Crimp a 14AWG ground cable to a ring lug (cable and lug not included) and then attach the ring lug to the ground stud on the firewall. Replace the star washers and nuts and torque to 25 in-lbs. Connect the other end of the cable to earth ground.
  3. Connect the AC power cord to the power input on the back of the firewall.
  4. Secure the power cords to the power supplies using the provided cord retainer.
    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.
  5. Connect the other end of the power cords to an AC power source. After the power supply is connected, the power supply powers on, the input and output LEDs on the power supply turn green, and the PWR LED and the power supply LED (PWR 1 or PWR 2) on the front of the firewall turns green.
    Connect the second power cord through a different circuit breaker to provide power redundancy and to allow for electrical circuit maintenance.
