The Platform package of J-Web is installed as part of Junos OS that is shipped with
your EX Series switch. The Platform package provides the basic features of the J-Web
interface. The Platform package enables you to configure and maintain your switch.
Application Package
The Application package is not installed by default on your switch. You must download
it and install it over the Platform package on your switch. The Application package
provides all the features of the J-Web interface that enable you to configure, monitor,
maintain, and troubleshoot your switch.
The Platform package, which is installed as part of the Junos OS that is shipped with
your switch, follows the Junos OS release cycle. However, the Application packages have
their own release cycle which is independent of the Junos OS release cycle. This separate
release cycle helps you get the latest features of J-Web by installing the latest version
of the Application package, without waiting for Junos OS releases.
NOTE: The J-Web Application package is hot-pluggable. You can install it
on top of the current Junos OS installation, and you need not reboot the
switch after the installation.
NOTE: To determine which J-Web package you are currently using, click Help

the J-Web Platform package that is associated with the upgraded Junos OS release. You
can then install the latest Application package that is associated with the main release of
the upgraded Junos OS, over the Platform package.
Release Compatibility
The Application packages of J-Web have their own release cycles (A1, A2, A3, and so on),
which are independent of the Junos OS release cycle. An Application package is
compatible only with the corresponding major release of Junos OS.
The Table 3 on page 5 illustrates the example of the release compatibility.
