Installing and Upgrading Firmware

 

To get the optimal network performance, and to fix a vulnerability, you can upgrade the firmware on your device.

Before You Begin Installing or Upgrading the Firmware

Before you begin installing or upgrading the firmware on the MIC or PIC, complete the following steps:

  1. Verify that a previous version of the firmware package is installed on the router by using the show version command.

    show version (MX240, MX480, MX960, MX2010, MX2020)

    user@host> show version

    show version (PTX3000 and PTX5000)

    user@host> show version

    show version (ACX6360)

    user@host> show version

    If the output of the show version command displays JUNOS jfirmware.. among the list of packages that are installed on the router, then a previous version of the firmware package is installed on the router. If the output of the show version command does not display JUNOS jfirmware.. among the list of packages that are installed on the router, the firmware package is not installed on the router.

  2. If a previous version of the firmware package is installed on the router, delete the firmware package from the router by using the request system firmware delete command. If a previous version of the firmware package is not installed on the router, then proceed to install the firmware package. For information about how to install the firmware package, see Installing Firmware on the 100-Gigabit DWDM OTN MIC (MIC3-100G-DWDM) or Installing Firmware on the 5-Port 100-Gigabit DWDM OTN PIC (PTX-5-100G-WDM) . For information about how to install the firmware package on ACX6360 router, see Installing Firmware on ACX6360 Router.
    user@host> request system software delete jfirmware
  3. To verify that the firmware package is removed from the router, use the show version command.
    user@host> show version

    show version (ACX6360)

    user@host> show version

    If the firmware package is uninstalled successfully, the output of the show version command does not display JUNOS jfirmware.. among the list of packages that are installed on the router.

Installing Firmware on the 5-Port 100-Gigabit DWDM OTN PIC (PTX-5-100G-WDM)

Before you install the firmware package, ensure that a previous version is not installed on the router. For more information, see Before You Begin Installing or Upgrading the Firmware.

To install the firmware package, complete the following steps:

  1. Upgrade Junos OS on the router to the version that supports the firmware package. See Installing the Software Package on a Device with Redundant Routing Engines or Installing the Software Package on a Router with a Single Routing Engine for more information.
  2. Download the firmware package from https://support.juniper.net/support/downloads/. For information about downloading software packages, see Downloading Software. Note

    Download the firmware package specific to your router. The firmware package for PTX Series routers is different from the firmware package for the MX Series routers.

  3. Save the firmware package to the /var/path/package-name directory on the router. For example, you can save the firmware package to the /var/tmp directory.
  4. Install the firmware package by using the request system firmware add path/package-name command. For example, to install the jfirmware-15.1F6.9.tgz package:
  5. Run the show version command to verify that the firmware package is installed.
    user@host> show version

    After the firmware package is installed successfully, the output of the show version command displays Junos jfirmware.. among the list of packages that are installed on the router.

Upgrading Firmware on the 5-Port 100-Gigabit DWDM OTN PIC (PTX-5-100G-WDM)

Before you upgrade the firmware package, ensure that a previous version is not installed on the router. For more information, see Before You Begin Installing or Upgrading the Firmware.

To upgrade the version of your firmware, complete the following steps:

  1. Run the show system firmware command to view the list of components installed on the router and the firmware version for each component.
    user@host> show system firmware

    The output of the show system firmware command displays the current firmware version of the PIC as .0 and the available firmware version as 1.0.

  2. To upgrade the firmware of the PIC, use the request system firmware upgrade pic command. For example, to upgrade the firmware version of the PIC from .0 to 1.0, specify the FPC slot and PIC slot in the command.
    user@host> request system firmware upgrade pic pic-slot 0 fpc-slot 2

    Confirm that you want to perform the firmware upgrade by typing Yes so the firmware upgrade is initiated.

  3. To monitor the progress of the upgrade, use the show system firmware command. During the installation process, the status of the PIC changes to PROGRAMMING. When the installation process is complete, the status of the PIC changes to UPGRADED SUCCESSFULLY.Note

    The amount of time it takes to upgrade firmware varies depending on the component.

    user@host> request system firmware
    Note

    If the installation process fails, delete the firmware package by using the request system software delete firmware-package-name command. Reinstall the firmware package by following the procedure for installing the firmware package and then upgrade the firmware package.

  4. Restart the FPC that the PIC is installed in by using the request chassis fpc fpc-slot restart command.
  5. (Optional) After the firmware upgrade is successfully completed, uninstall the firmware package from the router by using the request system software delete command.

Installing Firmware on the 100-Gigabit DWDM OTN MIC (MIC3-100G-DWDM)
