M4300 Boot Freeze after FW upgrade

Hi

 

I just went through the firmware upgrade on a M4300-28G switch from version 12.0.9.3 to 12.0.11.8. After the reboot the switch was not comming up again. Re-powering the switch and watching on the terminal what happens I figured that the switch starts normal until it dumps this line to the terminal: Applying Interface configuration, please wait ...

 

Then it freezes and will not continue to boot.

 

Anybody else experiencing this problem?

  • Hello

     

    I'm happy to announce that support just shared a new firmware version (12.0.11.10) with me which, after installation, works.

     

    Thank you NETGEAR!

     

    Best

  • Hi dialsc ,

     

    Welcome to NETGEAR community! :smileyhappy:

     

    I'm sorry about the Freeze on this M4300-28G.

    Since this M4300 can not bootup normally now even powercycle.

     

    Here is my suggestion to you for device recovery and troubleshooting(following screenshoot will help you on this)

    1. Connect the Console port to M4300 and keep press "ESC" button when you see the key word "Freeing init memory"

    2. Select “Active the backup image“ for workaround and then M4300 should bootup with backup image normally.

    3. If system bootup successfully, export configuration file to local backup.

       a) And also please export techsupport file and share to us for debugging.

       b) If possible, please also send the full console log when this issue happened and M4300 can not bootup.

    After you success active backup image and system bootup.

    1. Please do not upgrade this M4300 for now and try to share more information to us for debugging.

    2. The techsupport file is useful for debugging and also topology of this M4300.

     

    Our QA have also try to reproduce this probably issue but no lucky to see it.

      Hi DanielZhang 

       

      Thank you very much for your detailed answer and your help. I already went through the "recovery" by activating the backup image which worked, the switch is up and running again with the older firmware.

       

      As for the test with an "empty" config. I will try that later today.

       

      Meanwhile if you'd like I can send over the running config to you. Maybe Netgear's QA is interessted in?

       

      Best and thanks again
