Hi,


I'm having problems with a WS-X6K-SUP2-2GE module that is not booting up.


This is the output I get when trying to boot it up:


rommon 1 > i

You must reset or power cycle for new config to take effect

I followed the instructions on this document, uploaded a new version into the SUP through xmodem but still no luck:

Is there anything else I can do to recover from this behaviour?


Thanks,

Hi Pedro,


What IOS version you trying to boot ? I guess that you probably below required min memory which could be 256MB,

where you have only 128. And you need to have 256 on both - SUP & MSFC

Hi Arunas,


Thanks for your reply.


This a CatOS supervisor. I am trying it to boot from cat6000-sup2.6-4-4a.bin which is approximately 6MB in size. So I don't think memory is the issue here.


After some more reading I saw that this might be a problem related with the NVRAM need to use the battery (cr-2430) on board, if the battery ran out, then the NVRAM can not store the data.


If this is the case then I think RMA is my only chance.


Nonetheless please share your thoughts on this one.
