Installing Software on a Device


You can use this procedure to upgrade Junos OS on device with a single Routing Engine.

To install software upgrades on a device with a single Routing Engine:

  1. Download the software package as described in Downloading Software Packages from Juniper Networks.
  2. If you have not already done so, connect to the console port on the device from your management device, and log in to the Junos OS CLI.
  3. (Optional) Back up the current software configuration to a second storage option. See the Junos OS Installation and Upgrade Guide for instructions on performing this task.
  4. (Optional) Copy the software package to the device.

    This step is optional because Junos OS can also be upgraded when the software image is stored at a remote location. These instructions describe the software upgrade process for both scenarios.

  5. Install the new Junos OS image on the device:

    Replace package with one of the following paths:


    Trusted update with delayed activation is not supported by TOE.

    • For a software package in a local directory on the device, use /var/tmp/package.tgz.

    • For a software package on a remote server, use one of the following paths, replacing package with the software package name—for example, jinstall-ppc-19.1R2.8-signed.tgz.

      • ftp://hostname/pathname/package.tgz

      • http://hostname/pathname/package.tgz

  6. Reboot the device to load the installation:
  7. Once the router comes up with 19.1R2 build, copy and install fips-mode and jpfe-fips packages using request system software add fips-mode-powerpc-19.1R2.8-signed.tgz and request system software add jpfe-fips-powerpc-19.1R2.8-signed.tgz commands. Verify that the packages are successfully installed using show version command.
