JUNOS Installation Packages

The installation package is used to upgrade and downgrade from one release to another. When installed, the installation package completely reinstalls the software, rebuilds the JUNOS file system, and may erase system logs and other auxiliary information from the previous installation. The installation package does, however, retain the configuration files from the previous installation.

The following installation packages are available for download:

Installation PackageDescription

jinstall*

JUNOS software for the M-series, MX-series, T-series, and TX Matrix routers.

jinstall-ex*

JUNOS software for the EX-series Ethernet switch portfolio.

junos-jseries*

JUNOS software for the J-series routers.

junos-jsr*

JUNOS software with enhanced services for the J-series routers.

junos-juniper*

JUNOS-FIPS for the M-series, MX-series, T-series, and TX Matrix routers.

Once the package is installed on a routing platform, you cannot revert back to the standard JUNOS software installation without performing a software recovery procedure.
