This article describes troubleshooting with built-in FortiOS hardware diagnostic commands.
As described in the related article 'RMA Note: HQIP - Hardware Quick Inspection Package', HQIP can perform tests on a number of hardware elements. While it does not detect all hardware malfunctions, tests for the most common hardware problems are performed.
Traditionally, hardware diagnostics require users to download the HQIP image, then load the image on the device before the tests can be performed. Starting in FortiOS 5.4 with FortiGate E-Series models, HQIP tests are built into FortiOS itself. This allows users the convenience of performing hardware diagnostics without needing find the HQIP image and reloading the firmware image.
Note that no HQIP images will be produced for FortiGate E-Series and above that support built-in HQIP commands. Conversely, for units that require an HQIP image, continue using their designated HQIP images. See the "Running an HQIP Test" attachment to the related article 'RMA Note: HQIP - Hardware Quick Inspection Package' article for details.
