Installing Software on Network Services Platform with a Single Routing Engine

 

You can use this procedure to upgrade Junos OS on an NFX150 Network Services Platform with a single Routing Engine.

Note

Junos OS is delivered in signed packages that contain digital signatures to ensure the Juniper Networks software is running. When installing the software packages, Junos OS validates the signatures and the public key certificates used to digitally sign the software packages. If the signature or certificate is found to be invalid (for example, when the certificate validity period has expired or cannot be verified against the root CA stored in the Junos OS internal store), the installation process fails.

To install software upgrades on an NFX150 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 NFX150 device from your management device, and log in to the CLI. (For instructions, see Initial Configuration on NFX150 Devices.)
  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 NFX150 device. We recommend that you use FTP to copy the file to the /var/tmp/ directory.

    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 package on the NFX150 device:

    Replace package with one of the following paths:

    • For a software package in a local directory on the NFX150 device, use /var/tmp/package.tgz.

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

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

  6. Reboot the device to load the installation and start the new software:
