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 Package | Description |
jinstall* | Junos OS for the M Series, MX Series, T Series, TX Matrix, and TX Matrix Plus routers. |
jinstall-ex* | Junos OS for the EX Series Ethernet switch portfolio. |
junos-jsr* | Junos OS for the J Series routers. |
junos-juniper* | Junos-FIPS for the M Series, MX Series, T Series, TX Matrix, and TX Matrix Plus routers. Once the package is installed on a device, you cannot revert back to the standard Junos OS installation without performing a software recovery procedure. |
