Troubleshooting Tip : Collecting Logs for a FortiGate is not powering on

[msanjaypadma]

Description

This article describes how to handle a scenario where a FortiGate fails to power on, and how to collect relevant logs to diagnose the problem effectively.

Scope

FortiGate.

Solution

The following steps demonstrate how to troubleshoot, verify, and share information with a Fortinet TAC engineer when a FortiGate is not powered on.

1. Check the Power Source:

• Ensure that the power outlet is functional. Plug another device into the same outlet to verify.
• Confirm that the power cable is securely connected to both the power source and the FortiGate device.
  
  

2. Inspect the Power Cable and Adapter:

• Look for any visible damage to the power cable or adapter. If possible, replace it with a known working unit.
  
  

3. Check for Power LED Indicators:

• Observe the Power LED indicators on the firewall. If no lights are visible, the unit might not be receiving power. 

4. Check with an alternative PSU:

• For models equipped with additional power supplies, swap the power cable to an alternate power supply unit and check the device's status.
• If the Power LED is not illuminated, take a photograph of the unit, ensuring that the power supply cable is connected. Share this image with the Fortinet TAC support case.
• Additionally, if the Power LED is not blinking, connect a console cable to the device and capture any console logs that may be generated.
• If the Power LED is blinking but unable to access the device via LAN or WAN interface, access the firewall using the console cable. Gather the relevant information and provide this data to the Fortinet TAC support case for further assistance.
