A partition can contain one version of the firmware and the system
configuration. FortiGate-100A units and higher have two partitions.
One partition is active and the other is used as a backup.
A green check mark indicates the partition currently in use.
The date and time of the last update to this partition.
The version and build number of the FortiGate firmware. If your
FortiGate model has a backup partition, you can:
• Select Upload to replace with firmware from the management
computer or a USB disk. The USB disk must be connected to the
FortiGate unit USB port. See
• Select Upload and Reboot to replace the existing firmware and
make this the active partition.
Restart the FortiGate unit using the backup firmware.
This is available only for FortiGate-100 units or higher.
Select one of the available firmware versions. The list contains the
following information for each available firmware release:
• continent (for example, North America)
• maintenance release number
• patch release number
• build number.
For example, if you are upgrading to FortiOS 3.0 MR6 and the
FortiGate unit is located in North America, the firmware version
available is v3.0 MR6-NA (build 0700).
Select to allow installation of older versions than the one currently
installed.
This is useful if the current version changed functionality you need and
you have to revert to an older firmware image.
