## Upgrade Firmware

There are two possible ways to upgrade the firmware of the Power Platform controller. One way is to use the **Web-Based Management (WBM)** interface and the other way is to use
a **Shell session**. Regardless of the two options to update the firmware version of the controller, you first need to download the firmware from the Phoenix Contact website. For that:

  </Step>
</Steps>

### Through Shell Session

<Steps>
  <Step title="Copy Firmware File">
    Copy the `axcf2152-2025.0.3-25.0.3.99.raucb` file from the extracted ZIP archive to the controller using SCP (Secure Copy Protocol):

    ```bash theme={null}
    scp axcf2152-2025.0.3-25.0.3.99.raucb admin@192.168.1.10:~
    ```

    Alternatively, use an FTP (File Transfer Protocol) software such as FileZilla to copy or move the `.raucb` file to the controller.
  </Step>

  <Step title="Open Shell Session">
    Open a shell session:

    ```bash theme={null}
    ssh admin@192.168.1.10
    ```

    Enter the default password (printed on the housing of the controller).
  </Step>

  <Step title="Stop Controller Runtime">
    ```bash theme={null}
    sudo /etc/init.d/plcnext stop
    ```
  </Step>

  <Step title="Install Firmware">
    ```bash theme={null}
    rauc install axcf2152-2025.0.3-25.0.3.99.raucb
    ```
  </Step>

  <Step title="Reboot Controller">
    ```bash theme={null}
    sudo reboot
    ```
  </Step>
</Steps>

Verify in the WBM that the firmware version has been updated to version 2025.0. Please refer to previous section for more information on how to check the current firmware version.
