Error when starting BCM 450 R6 after an upgrade

[pietr0100]

Hello, I' have an issue when upgrading a BCM 450 with R6.

This was originally a BCM 400 R4 then I change the hardware and make an upgrade to BCM450 R6.
But I'm having a lot of issues. The Technical support team told me that I have a corrupt HD, but with or without the HD I have the following error:
* The two leds are always in orange Nortel and Power.

And it just go on and on and I can't make it work.

PLEASE anyone help me addressing this issue.
