Retrieving a BTI7800 Software Image


Use this procedure to retrieve a BTI7800 software image from the Juniper Networks software download page. BTI7800 software is available as an RPM file or as a gzipped USB image.

  • Download the RPM file if you are upgrading software using CLI commands.

  • Download the gzipped USB image if you are upgrading software using a system repair drive. A system repair drive installs software onto a CMM from the USB port.


  • A computer running Linux, Mac OS X, or Windows

  • Internet access capable of transferring large files

  • A user login account on

  • If using Windows, a file archiver program (to gunzip the USB image)

  1. Use your browser to go to
  2. From the By Series drop-down list, select BTI7800 Series and then select the desired chassis type from the BTI7800 family.

    The browser displays the download page for the selected chassis type.


    The same software image is used for all BTI7800 chassis types.

  3. Click the Software tab.
  4. Select the desired software release from the Version drop-down list.
  5. Click the RPM file or gzipped USB image that you want to download.
  6. If you are not already logged in, the browser displays a login screen.
    1. Enter your User ID and Password.

    2. Read through the EULA, select I Agree, and click Proceed if you agree with the terms of the EULA.

  7. The download begins automatically. If your operating system prompts you to save or open the file, choose the Save File option or equivalent.

    Depending on the speed of your Internet connection, the download might take 30 minutes or longer.

    The RPM filename is in the format bti7800-sys-sw_version.x86_64.rpm.

    The USB image is a GZIP compressed file. The filename is in the format bti7800-usb-sw_version.gz.

  8. On your browser, go back to the download page and click on MD5 SHA1 to view the checksum of the corresponding download. Note that the checksums are different between the RPM file and the gzipped USB image.

    Both the MD5 and SHA1 checksums appear in a pop-up window.

  9. Verify the checksum of the downloaded image with the expected checksum. The examples below verify the MD5 checksum for a gzipped USB image download.
    1. On a Linux command line, for example:

    2. In a Mac OS X terminal window, for example:

    3. On a Windows command line, for example:

    Compare the file-checksum from the output of the command with the checksum displayed in step 8. If the checksums do not match, download the image again and re-verify the checksum.

  10. Copy the downloaded file to the desired location.
    • Copy the RPM file to the FTP server that you use to distribute software loads to your network elements.

    • Copy the gzipped USB image to a location that is accessible from the computer that you are using to create the system repair drive.

    If you are downloading an RPM file, you have completed this procedure.

    If you are downloading a gzipped USB image, proceed to the next step.

  11. Uncompress the gzipped USB image.
    1. On a Linux command line, for example:

    2. On Mac OS X, double-click the gzipped file to uncompress and save the extracted image.

    3. On Windows, download and use a file archiver utility (for example, 7zip) to uncompress and save the extracted image.

    The USB image has been downloaded and extracted successfully. You can now proceed to create the system repair drive.
