Installing and using a backup firmware image, 103 | Fortinet 400

System status	Changing the FortiGate firmware

Note: The local IP address is only used to download the firmware image. After the firmware is installed the address of this interface is changed back to the default IP address for this interface.

The following message appears:

Enter File Name [image.out]:

11Enter the firmware image file name and press Enter.

The TFTP server uploads the firmware image file to the FortiGate unit and messages similar to the following appear.

•FortiGate unit running v2.x BIOS

Do You Want To Save The Image? [Y/n]

Type N.

•FortiGate unit running v3.x BIOS

Save as Default firmware/Run image without saving:[D/R]

Type R.

The FortiGate image is installed to system memory and the FortiGate starts running the new firmware image but with its current configuration.

12You can login to the CLI or the web-based manager using any administrative account.

13To confirm that the new firmware image has been loaded, from the CLI enter:

get system status

You can test the new firmware image as required.

Installing and using a backup firmware image

If your FortiGate unit is running BIOS version v3.x, you can install a backup firmware image. Once the backup firmware image is installed you can switch to this backup image when required.

This section describes:

•Installing a backup firmware image

•Switching to the backup firmware image

•Switching back to the default firmware image

Installing a backup firmware image

To run 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 the FortiGate as described in the procedure “Install a firmware image from a system reboot using the CLI” on page 99.

To install a backup firmware image:

1Connect to the CLI using the null modem cable and FortiGate console port.

2Make sure that the TFTP server is running.

3Copy the new firmware image file to the root directory of your TFTP server.
