3.5 Upgrading
Software
Using TFTP (option 2)
Upgrading the application image with the Ethernet SubMenu will use an Ethernet interface to
download the application. In this approach, the router is the TFTP Client and needs to connect
to a TFTP Server using a fixed Ethernet interface. The following describes how to upgrade the
application image with this approach:
1
Start the TFTP Server on the host connected to the Ethernet interface on the router. Set the
path for the source file to be downloaded.
Caution:
No TFTP Server is available on the routers. You must have a TFTP server available.
2
In the Boot Menu, select option 3 to enter the Ethernet SubMenu (shown below):
