MainbMainboard authentication failed

[malhalafi]

I have issues with our switch, including an appearance notification that says "MainbMainboard authentication failed." Abort init... 

and I open tieckt with cisco and request me provide below information :

• switch:set
• switch:version
• switch:gettlv
• switch:dir flash:

but I can't provide this information because of this problem.

Console into the switch and reboot. 
Post the entire boot-up process.

Let us be the judge of that. 
I want to see the boot-up process.

Kindly provide the serial number of the switch. 

IMPORTANT:  I only want to see the first seven characters of the serial number.  Leave the last four characters out.

Contact Cisco TAC and organize for an RMA.

serial number :FCW2219

and what's mean (RMA)??

Contact Cisco TAC and tell them the switch is dead.  
RMA means TAC will send a replacement for free.

I was already suggested you for  raise a RMA for the device replacement with cisco tac couple of bugs reported for the same and cisco already recommended to raise RMA ticket for that.
