Installing Junos Continuity Software Package to Support New Hardware

 

You install the Junos Continuity software package to enable a router to support new hardware without the need to upgrade Junos OS. You can install the Junos Continuity software package as a standalone package or as a package bundled with Junos OS.

If graceful Routing Engine switchover (GRES) is enabled, you must install the Junos Continuity software package on both the primary and the backup Routing Engines to ensure that the hardware components remain operational after a Routing Engine switchover.

Note

Before you proceed with the installation, verify that the version of Junos OS that is installed on the router supports Junos Continuity software.

You can consider one of the following methods to install Junos Continuity software:

  • Install the Standalone Junos Continuity Plug-in—Upgrade of Junos OS is not required. You install the Standalone Junos Continuity Plug-in if the version of Junos OS that is installed on the router supports Junos Continuity software. For example, if the router is running Junos OS Release 15.1F4, you can directly install Standalone Junos Continuity Plug-in and then bring the line cards online.

    After you install Junos Continuity software, you can bring the new line card online by using the request chassis fpc slot-number online command.

    This topic guides you through the installation of the Standalone Junos Continuity Plug-in on 64-bit Junos OS.

  • Install the Junos Continuity Plug-in Integrated with Junos OS—Requires you to upgrade Junos OS. You use the integrated package if the version of Junos OS that is installed on the router does not support Junos Continuity software. For example, if you want to install Junos Continuity software on Junos OS Release 13.3, you can use the integrated package that contains both Junos OS Release 15.1F4 and the Junos Continuity Plug-in. This is a one-step process to upgrade Junos OS to Junos OS Release 15.1F4 and also to install Junos Continuity software. See Software Installation and Upgrade Guide for more information about upgrading Junos OS.

Note

To upgrade the Junos Continuity software package, you can just install the new package on the router. The installed version of Junos Continuity software gets overwritten when you install a later version.

Before you begin installing Junos Continuity software:

  1. Download the Junos Continuity software package from https://www.juniper.net/support/. For information about downloading software packages, see Downloading Software.

  2. Install the new line cards by following the procedure given in the router’s hardware guide.

  3. (Optional) Run the run show chassis fpc command to verify the status of the new line cards.

    For example, the following sample output displays information about all the line cards installed on the router:

    The newly installed line cards are displayed as FPC incompatible with SCB because the router cannot recognize them.

Installing the Junos Continuity Software Package

This section provides the steps to install the Junos Continuity software package.

To install the Junos Continuity software package:

  1. Run the request system software add path/package-name command to start installation of the Junos Continuity software package on the master Routing Engine. For example, to install the jam-mpc7-8-9-x86-64-15.1F4.15-C1.9 package:
    Note

    Juniper Networks recommends that you do not use the validate option when you install the Junos Continuity software package. If you use the validate option, you need to restart the router to activate the Junos Continuity software package.

  2. Run the show version command to verify the installation.

    After Junos Continuity software package is installed successfully, the output of the show version command displays JUNOS 64-bit JAM Plugin Software Suite among the list of packages that are installed on the router.

  3. (Optional) Run the request system software add path/package-name command to install Junos Continuity software package on the backup Routing Engine. For example, to install the jam-mpc7-8-9-x86-64-15.1F4.15-C1.9 package:
  4. (Optional) Run the show chassis fpc pic-status command to display the status of the new line card.

    For example, the following sample output shows the status of the new line card installed in slot 19.

    Note

    The status Present indicates that the router can recognize the new line cards. To make the new line cards operational, you must bring them online.

  5. Run the request chassis fpc slot slot-number online command to bring the newly installed line card online.

    For example, the following sample output shows that the line card is being brought online.

  6. (Optional) Run the show chassis fpc pic-status command to display the status of the newly installed line card.

    For example, the following sample output shows the status of the line card in slot 19 and the installed PICs.

    The newly installed line card and PICs are online and operational.

  7. Run the show system software detail command the verify whether the Junos Continuity software package is installed and the hardware components that the package supports.

    For example, the following sample output shows that Junos Continuity package installed on the router and supports MPC7E.
