6850 stuck in Vxworks mode, doesn't load MiniBoot

[AcMe]

Posted this new topic 2/11 but it didn't show in forum?? Well, well, I try again.

The problem is that the switch hangs in vxWorks mode:

"U-Boot (6.3.4.265.R01) (for OS6400, OS6850, and OS6855 platforms) (Dec 15 2008 - 21:31:42)

The next line is supposed to like something like this:
"ataDrv call. 0 1 24 24 621 0 0"

But this line never shows....

Any clue what to do next?

Sincerely,
Stefan

I don't know what to do. You can try to exchanche the flash card with an other switch for finding the issue. Also I had have a similar issue (2 times): the power supply was the reason. You can exchange this.
But sometimes also an alcatel-switch goes damaged. Then you can use the lifetime warranty - this is an advanced replacement.
Do you know what was with the switch before the issue: does it work fine a long time or is it a new one? Was there a power interuption?

Just before a reply was posted, I actually tried with a different powersupply!
Now the switch is back in business!

Thank you for the attention!
