Question

Has anyone successfully installed 7.4.7 on 1048E Fortiswitches?

I only have 1 non-prod switch I can use, and I upgraded from 7.2.0(?) to 7.4.7

After upgrade, web GUI just showed Server Error 500, although I could still ssh into the switch.

After switching boot to the secondary partition (still on 7.2.0) I was able to get back into GUI. I then upgraded incrementally, and all versions worked until 7.4.6. Trying to upgrade from 7.4.6 to 7.4.7 again gave me Server Error at the GUI.

Is anyone successfully using 7.4.7 on 1048E platform?

Verify there are no crashlogs reported. 

 

Looks like there might be a known issue with FortiGate. You might need to contact the Fortinet TAC Support with the tac report of the switch.

    Follow this Troubleshooting Tip: '500 Internal Server Error' on FortiSwitch GUI after upgrade to 7.4.7 | Community

    If debug output shows ‘access_res_check.c[ 88] : Received '/access_res_check' request from 'xx.xx.xx.xx’ you can upgrade to 7.4.8 or 7.4.8+ for fix.

        Having the Bug ID and direct links to the release notes makes it much easier to understand what’s going on and how to fix it. The upgrade suggestion to 7.4.9 is clear and straight to the point too.

        Solid response, this will definitely help others running into the same issue..
