Power Over Ethernet (PoE)

Configure Power Over Ethernet (PoE) to route electrical power from your firewall to another network device.
You can configure Power Over Ethernet (PoE) on the interfaces of supported firewalls to transfer electrical power from the firewall to a connected network device. This allows you to meet the power needs of other devices while continuing to transmit data to them using a single Ethernet cable per physical PoE port.
This table lists each Palo Alto Networks® Next-Generation firewall with PoE ports as well as the maximum power they offer, the total allowed power budget, and the interface types they support.

The following task describes the procedure for setting up PoE on your firewall.
  1. Ensure that the device you want to provide power to is connected to the firewall using an Ethernet cable through a supported PoE port on the firewall.
    Using a Cat5 or Cat6 Ethernet cable ensures the most reliable power transfer. A Cat3 cable, for example, will only be able to transfer as much as 20W.
  2. Select
    Network
    Interfaces
    Ethernet
    and choose the interface you have cabled.
  3. PoE is active on all PoE ports by default. On the Ethernet Interface window, selecting
    Advanced
    and viewing
    PoE Settings
    shows that
    PoE Enable
    is already enabled.
  4. Set the amount of power reserved by the port by entering a value (in Watts) for
    PoE Rsvd Pwr
    . This value must be a number between
    0
    and the Maximum Reserved Power of the port as defined in the table above. A
    0
    indicates that no power will be sent through the port connection.
    The total
    PoE Rsvd Pwr
    of all of your PoE ports should not exceed the Total PoE Budget Allowed in the table above. If you go over the Total PoE Budget Allowed, one or more powered devices will enter the
    Den
    (Power Denied) state until you reallocate the reserved power.
    If no device is connected to a PoE port, ensure that either
    PoE Enable
    is disabled or the
    PoE Rsvd Pwr
    value is
    0
    to avoid consuming a portion of the PoE budget.
