Connect DC Power to a PA-5200 Series Firewall

The following procedure describes how to connect DC power to a PA-5200 Series firewall with DC power supplies.
To avoid injury to yourself or damage to your Palo Alto Networks® hardware or the data that resides on the hardware, read the Product Safety Warnings.
  1. Remove the two nuts and star washers from the ground studs on the back of the firewall and then remove the two-hole ground lug.
  2. Crimp a 6AWG ground cable (not included) to the two-hole 6AWG ground lug and then attach the ground lug to the ground studs 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. Power off the DC power source that you will connect to the firewall.
  4. Attach the DC power cables (not included) from the DC power source to the DC power supplies on the back of the firewall.
    1. Remove the plastic DC power input cover from each of the two DC power supplies and then remove the positive and negative terminal screws.
    2. Crimp ring lugs to the ends of the DC cables. These lugs are used to connect the DC cables to the DC inputs on the firewall.
    3. Use the DC terminal screws to connect a positive (red) DC power cable to the positive terminal on the first DC power supply and then connect a negative (black) DC power cable to the negative terminal. Repeat this step for the second DC power supply using separate positive and negative cables.
    4. Replace the plastic covers over each DC power input.
    5. Connect the two positive and two negative DC power cables to your power source, ensuring that you observe the correct polarity (positive to positive and negative to negative).
  5. After all DC power cables are securely connected, power on the DC power source.
