To upgrade the JUNOS Internet software on a Services Router, you install a new version that you download from the Web to a remote server or your computer. Use either the J-Web interface or the CLI to perform the upgrade.
If you need to replace the primary boot device or add a backup boot device on the router, you can configure a boot device with the CLI or with a UNIX or Microsoft Windows computer. You can also configure a boot device to receive core dumps.
Use either the J-Web interface or the CLI to schedule a reboot or system halt on the router, or to perform one immediately.
For more information about installing and upgrading JUNOS software, see the JUNOS System Basics Configuration Guide.
