Installing firmware images from a system reboot using the CLI
This procedure installs a specified firmware image and resets the FortiGate-5000
module to default settings. You can use this procedure to upgrade to a new firmware

For this procedure you:
•
access the CLI by connecting to the FortiGate console port using a null-modem
cable,
•
install a TFTP server that you can connect to from port8. The TFTP server should
be on the same network as port8.
Before beginning this procedure you can:
•
Back up the FortiGate-5000 module configuration.
For information, see
the
FortiGate Administration Guide
