Console directly onto the secondary SUP and see what state it is in, this will at least give you a clue as to what the next steps should be and if unclear, at least you can let us know so we can advise.

I would check that it has a valid IOS to boot from in flash, (make sure this is the same as your other SUP if you intend to us this as a backup SUP).


If it doesn't you will need to copy an image over and then reboot it, here is a URL with ROMMON commands :-

When you are in rommon via console, and you type :-


boot :.bin


how far does it get and what error messages do you see?

Hi


I think you will have to open a case with Cisco and supply this info to them as it looks like you SUP is broken but they will be able to tell you for sure. Hopefully it's not but it doesn't look good.

I agree with Adam. Your Sup most probably reloaded and failed to complete the reload due to %Software-forced reload. If you check the Sup bootdisk you'll probably find a number of crashinfo directories.


You need to find out why this is happening. There's almost 200+ identified crash-causing bugs for the SXF14 IOS.
