3.2.4 Upgrading Application Programs with NET
Upgrading an application program with net is to download the application program through an
Ethernet interface. In this approach, the router is a client that needs to be connected to a TFTP or
FTP server through one of its fixed Ethernet interfaces.
Caution:

Follow these steps to upgrade an application program through TFTP or FTP:
1) Start the TFTP or FTP server
Start the TFTP or FTP server on the PC connected to the Ethernet interface on the router and set
the path to the file that is to be downloaded. For the FTP server, you must also set username and
password.
2) Enter the Boot Menu and select <2> to download with NET
3) In the NET download menu, select <1> to enter the parameter configuration interface.

file name: name of the file to be loaded.
inet on ethernet (e): IP address of the interface used for downloading on the router
