sup problems C6006

[dan]

SUP1 shows Pinnacle error and continually reboots itself, have tried loading new IOS with xmodem but it will still not boot. Problem began after installation of a WS-X6348-RJ-45. Cannot get to console at all can anyone suggest a resolution.

Thanks

What is the exact error you are seeing? If you are seeing Pinnacle Synch Failed messages, try the following

We are getting the following output on boot:

If there is a fault with the 6348 could that cause a failure in the SUP1?

SUP1 was operating fine in the Chassis until the 6348 was installed.

Yes..Try powering up the switch without the line card. Also, try the ethernet card in a different slot. Make sure that Sup as well as the line cards are seated fully and the thumb screws tightenend

We have tried every possible configuration - SUP and 6348 in every slot, seated and screwed down.

The problem occurred after installing a 6348, and it's removal or movement has had no effect on the problem.

It would seem to me that the installation of the 6348 has somehow corrupted the config stored in NVRAM (we have tried booting from slot1 instead of onboard flash, but still get the same error so NVRAM would seem to be the only option.) I can't think of a way of clearing NVRAM with only romon as an interface, might there be a way of doing this short of putting the SUP1 in another chassis with a working SUP1?
