Resolution; Instruction Steps - Fortinet FortiGate FG-80C Manual

Resolution

This issue can be corrected and prevented from occurring by re-formatting the flash file system and
removing the hidden partition. This operation will take approximately 10 minutes to perform,
FortiGate console access and a local TFTP server are required, the basic procedure is similar to
loading an HQIP test image, during the operation the device will be out of service.
Following are the detailed steps and procedures required to perform the re-formatting, the main
components required for these upgrade steps are:
• Console access to the FortiGate
• TFTP server connected to port internal1 of the FG80C
• Disk format image
• Desired FortiOS image

Instruction Steps

Depending upon the hardware model type the following format images will be required:

FortiGate FG80C - FGT_80C-FORMAT.3.0.0.1001.out

FortiGate FG80CM - FGT_80CM-FORMAT.3.0.0.1012.out

a) Save the image to the TFTP root folder, example as follows:
C:\TFTP-Root\ FGT_80C-FORMAT.3.0.0.1001.out

fail to function properly!
