!!! Warning: This switch is not usable !!!

Unanswered Question
Feb 24th, 2007

I have a 3550 Catalyst switch once I power it up, It displays this error message "!!! Warning: This switch is not usable !!!". When I did show run, both the Gigabitethernet/fastethernet ports did not display. If I plug my laptop to the switch my LAN connection shows connected but no light displays on the switch. I assumed the switch has hardware error, or can somebody figure out what the problem is. I have change the IOS several time but still the same problem.

I have this problem too.

After that error there will be another line that will tell the cause of the error. Are you still able to collect the output for show tech-support?
