Connect Power to a PA-400 Series Firewall
    
    Connect power to a PA-400 Series firewall in preparation for the initial
        bootup.
    All PA-400 Series firewalls, except for the PA-455-5G, are powered by an external
                        power adapter that converts an AC power source to DC power. The PA-455-5G
                        firewalls operates on AC power.
All firewalls, except for the PA-410, support power redundancy.
