Cisco 3550: Data bus test failed for associated data

Unanswered Question
Sep 29th, 2010

Hello Guys, I have Cisco 3550 switch. When i switch it on, i can login to the global configuration mode. But i cant view any interfaces. I am getting a message saying "data bus test failed for associated data". Is this is reolvable? Or is it is a hardware issue?

I have attached the show run and show version output below.

Is it is possible to figure out what is the problem and any means of rectifying it..??

Sometime ago, I've seen this error and the device was hardware fault, as far as I remember.
