    Replace a PA-500 Series Firewall Power Supply

    Learn how to replace a power supply on the PA-500 Series Firewall.
    The PA-500 Series firewalls can operate on one power adapter. All of the PA-500 Series firewalls support the connection of a second power adapter for power redundancy. If two power adapters are installed and one fails, you can replace the failed power adapter without interruption.
    To avoid injury to yourself or damage to your Palo Alto Networks® hardware or the data that resides on the hardware, read the Safety Warnings.
    1. Unplug the failed power adapter from the AC power source and then disconnect the cable plugged into the firewall.
    2. Connect the DC connector from the new power adapter to the first power input port on the firewall and ensure that it is secure.
    3. Plug the AC connector from the power adapter into an AC power source.
