Fortinet FortiGate-30B Manual Do Utilizador

Make sure the FortiGate unit can connect to the TFTP server. 

You can use the following command to ping the computer running the TFTP 
server. For example, if the TFTP server’s IP address is 192.168.1.168:

execute ping 192.168.1.168

Enter the following command to copy the firmware image from the TFTP server to 
the FortiGate unit: 

execute restore image <name_str> <tftp_ipv4>

Where <name_str> is the name of the firmware image file and <tftp_ip4> is 

the IP address of the TFTP server. For example, if the firmware image file name is 
imagev28.out and the IP address of the TFTP server is 192.168.1.168, enter: 

execute restore image image28.out 192.168.1.168

The ForitGate unit responds with this message: 

This operation will replace the current firmware version!
Do you want to continue? (y/n)

Type y.
The FortiGate unit uploads the firmware image file. After the file uploads, a 
message similar to the following appears:

Get image from tftp server OK.
Check image OK. 
This operation will downgrade the current firmware version!
Do you want to continue? (y/n)

Type y.
The FortiGate unit reverts to the old firmware version, resets the configuration to 
factory defaults, and restarts. This process takes a few minutes. 

Reconnect to the CLI.

To restore your previous configuration, if needed, use the command: 

execute restore config <name_str> <tftp_ip4>

Update antivirus and attack definitions using the command:

execute update-now. 

This procedure installs a firmware image and resets the FortiGate unit to default 
settings. You can use this procedure to upgrade to a new firmware version, revert 
to an older firmware version, or re-install the current firmware.

To use this procedure, you must connect to the CLI using the FortiGate console 
port and a RJ-45 to DB-9, or null modem cable.

This procedure reverts the FortiGate unit to its factory default configuration. 

For this procedure you install a TFTP server that you can connect to from the 
FortiGate internal interface. The TFTP server should be on the same subnet as 
the internal interface. 

Before beginning this procedure, it is recommended that you back up the 
FortiGate unit configuration.
