CISCO 2921 ROUTER WITH LOUD NOISE

[benojefua]

I have a 2921 router which has suddenly started making a loud noise. I assume this is from the fans. The system LED light is also amber. Any ideas what might be causing this and ways to resolve?

Thanks.

Contact Cisco TAC and organize for an RMA.  

The sound you hear is the sound of the motherboard "frying" and the above logs prove it.
