Updating J-Web Interface on EX Series Switches (J-Web Procedure)

You can update the J-Web software packages on a single fixed-configuration switch or for all members of a Virtual Chassis.

You can use the J-Web interface to install the latest Application package that is associated with the installed Junos OS, from a server by using FTP or HTTP, or by uploading the file to the switch.

There are two ways in which you can use the J-Web interface to download and install the J-Web Application package:

  • Auto update

  • Manual update

Installing J-Web Application Package by Using Auto Update

To automatically check for and install the latest version of the J-Web Application package:

  1. Click Update Now in the Update Available window that appears when you log in to the J-Web interface.
    Note:
    • For the Update Available window to appear when you log in, your switch or computer should be connected to the Internet.

    • The Update Available window appears only if there is a latest update available on the Juniper Networks server.

    • For the Update Available window to appear when you log in, the Check for updates automatically on every login in the Update Preference section in the Maintain > Update J-Web side pane must be selected.

    • If you choose Update Later, you can update to the latest J-Web Application package by clicking the orange icon next to Update Available on the top pane of the J-Web interface or through Maintain > Update J-Web.

  2. If the switch is connected to the Internet, the Update J-Web window appears. Enter the authentication details to download from the Juniper Networks download server. The J-Web Application package downloads and installs on the switch.

    If the switch is not connected to the Internet and your computer is connected to the Internet, download the latest version of the J-Web Application package to your computer and install it on your switch. Click Download Application Package in the Update J-Web window, enter authentication details to download from the Juniper Networks download server, and download the file to your computer. Select the file and click Update.

    Note:

    You can also download the file to your computer and update it on the switch later by clicking Select Application Package in the Maintain > Update J-Web side pane, and selecting where the package is located.

Installing J-Web Application Package by Using Manual Update

To manually check for and install the latest J-Web Application package:

  1. Go to Maintain > Update J-Web in the side pane, and click Check for updates.

    If the latest update is available on the Juniper Networks server, the Update Available window appears.

  2. Click Update Now in the Update Available window.
  3. If the switch is connected to the Internet, the Update J-Web window appears. Enter the authentication details to download from the Juniper Networks download server, and click Update. The J-Web Application package downloads and installs on the switch.

    If the switch is not connected to the Internet and your computer is connected to the Internet, download the latest version of the J-Web Application package to your local computer and install it on your switch. Click Download Application Package in the Update J-Web window, enter authentication details to download from the Juniper Networks download server, and download the file to your local system. Select the file, and click Update.

    Note:

    You can also download the file to your computer and update it on the switch later by clicking Select Application Package in the Maintain > Update J-Web side pane, and selecting where the downloaded package is located.
