Upgrading flash firmware via TFTP
Trivial File Transfer Protocol (TFTP) is a simplified version of FTP that allows transfer of files between
computers over a network. An alternative method to flash upgrades via HTTP is to install and configure a
TFTP server and use that for flash upgrades.
Note: Although TFTP is an option for upgrading, this program is not supported by McAfee technical support.
Prerequisites:
• Download the binary image file (.sgu). Go to the product Web site for instructions on obtaining this file.
The UTM Firewall Firmware Upgrades page is available from

.
• Place the .sgu file in the directory your TFTP is serving files from, usually:
/tftpboot/.
To flash upgrade with TFTP, you can either use the Flash Upgrade (TFTP) page or run a command on the
command line interface.
