Installing Software Upgrades from a Remote Server

To install the software upgrades from a remote server:

1. Install the JUNOS software package on the Services Router, entering the following command in operational mode in the CLI:

   user@host> request system software add validate unlink no-copy source

   Replace source with one of the following paths:

   • ftp://hostname/pathname/package-name

     or

   • http://hostname/pathname/package-name

   By default, the request system software add command uses the validate option to validate the software package against the current configuration as a prerequisite to adding the software package. This validation ensures that the router can reboot successfully after the software package is installed. This is the default behavior when you are adding a software package.

   The unlink option removes the package at the earliest opportunity so that the router has enough room to complete the installation.

   (Optional) The no-copy option specifies that a software package is installed, but a copy of the package is not saved. Include this option if you do not have enough space on the CompactFlash card to perform an upgrade that keeps a copy of the package on the router.

2. After the software package is installed, reboot the router:

   user@host> request system reboot

   When the reboot is complete, the router displays the login prompt.
