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. Identify the failed power supply by viewing the
    logs or by viewing the power supply status LEDs (see Interpret the PA-3200 Series Status LEDs).
    Power off the DC power source that is connected to the failed power supply, before you continue to the next step.
  2. Remove the plastic cover that protects the DC input terminals and then use a Phillips-head screwdriver to remove the screws holding the positive and negative DC cables to the DC input terminals.
  3. Grasp the handle on the failed power supply and then simultaneously press the release lever to the left and pull the power supply outward to remove it.
  4. Remove the replacement power supply from the packaging and slide it into the empty power supply slot. Push the power supply all the way in until the release lever clicks and secures the power supply.
  5. Reconnect the positive and negative DC power cables to the new power supply using the DC terminal screws.
    Make sure you establish the correct polarity: positive to positive and negative to negative.
  6. When all DC power cables are securely connected and the plastic guard is properly reattached, power on the DC power source. The power supplies powers on, the input and output LEDs on the power supplies turn green, and the PWR LED and the power supply LEDs (PWR 1 and PWR 2) on the front of the firewall turns green.
