About software upgrade
At the web interface, you can upgrade software, specify the main/backup software, and remove
software files.
Software upgrade is performed with TFTP (see Figure 6-12). Therefore, to download a software
upgrade file from a TFTP server, you must set the IP addresses of your U200 series device (the TFTP
client) and the TFTP server correctly and ensure that they are reachable to each other.
