Installing Software on an NFX250 Network Services Platform with a Single Routing Engine (FIPS Mode)


You can use this procedure to upgrade Junos OS on an NFX250 Network Services Platform with a single Routing Engine.

To install software upgrades on an NFX250 device with a single Routing Engine:

  1. Download the software package as described in Downloading Software Packages from Juniper Networks (FIPS Mode).
  2. If you have not already done so, connect to the console port on the NFX250 device from your management device, and log in to the JDM CLI. (For instructions, see Configuring an NFX250 Device.)
  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 NFX250 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 NFX250 device:

    Replace package with one of the following paths:

    • For a software package in a local directory on the NFX250 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:
  7. After the reboot has completed, log in and use the show version command to verify that the new version of the software is successfully installed. If you installed the Junos FIPS mode package, verify that the FIPS mode utilities are present—as shown in the following example:
