If the Status page shows a success, click Home to continue with the upgrade and return to the Console page.

Installing Software on Upgrade Link installs the software on the NMS in the following directory: the NMS

Windows:

\%tftpboot%\image\<platform>\SWFW\<version>\<pkg>

UNIX:

/tftpboot/image/<platform>/SWFW/<version>/<pkg>

For UNIX, if there is not enough space on the disk, you can link /tftpboot to another disk. For example, to link /tftpboot to the usr directory, enter:

ln -s /usr/tftpboot /tftpboot/

The utilities work only with the default directory names and structures.
