Q: No image on my brand new Thunderbolt 27" Display

I just purchased the TB 27 inch to work with my brand new MacBook Pro 15" and my MacBook Air (model mid 2012). I get no image on the TB display. Apple profile says under TB: "No devices connected"

 

I'm running Mountain Lion on both laptops.

 

Did anyone experience a similar situation?

Do I need to update any firmware or so?

 

pls help.

Apple Thunderbolt Display (27-inch), OS X Mountain Lion (10.8.1)
