If there are modules attached, remove them and reboot the switch.

Could you try a different IOS? Try the latest 15.0(2)SE train.
You'll need to force the switch to boot into ROMmon and force the switch to boot the IOS using USB.

I have already upgraded it to latest ios: Version 15.2(4)E6, RELEASE SOFTWARE (fc4)

Leo Laohoo · ‎10-08-2018

Try a different version. The latest 15.0(2)SE is a good one to use.

Abhishek Nanda · ‎10-08-2018

Hi Leo

Your solution worked. But I dont want it to happen each time the switch reboots. Again after installing the modules the same issue persists. Please suggest a permanent solution to this problem.
