Fortinet 110C 用户手册

You can test a new firmware image by installing the firmware image from a system 
reboot and saving it to system memory. After completing this procedure, the 
FortiGate unit operates using the new firmware image with the current 
configuration. This new firmware image is not permanently installed. The next time 
the FortiGate unit restarts, it operates with the originally installed firmware image 
using the current configuration. If the new firmware image operates successfully, 
you can install it permanently using the procedure 

. 

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 temporarily installs 
a new firmware image using your current 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. 

Connect to the CLI using a RJ-45 to DB-9 or null modem cable. 

Make sure the TFTP server is running.

Copy the new firmware image file to the root directory of the TFTP server.

Make sure the internal interface is connected to the same integer as 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 restart the FortiGate unit:

execute reboot

As the FortiGate unit reboots, press any key to interrupt the system startup. As the 
FortiGate unit starts, a series of system startup messages appears.
When the following messages appears:

Press any key to display configuration menu....

Immediately press any key to interrupt the system startup.

If you successfully interrupt the startup process, the following messages appears:

[G]: Get firmware image from TFTP server.
[F]: Format boot device.
[Q]: Quit menu and continue to boot with default
firmware.
[H]: Display this list of options.

Enter G, F, Q, or H:

Note: You have only 3 seconds to press any key. If you do not press a key soon enough, 
the 

FortiGate

 unit reboots and you must login and repeat the execute reboot 

command.
