AS2511-RJ - NVRAM verification failed - want to try running different version of OS

[marshallkelly]

Hi, I suspect my terminal servers are no longer supported but I'm hoping to try to recover one that cannot remember it's config. The problem was detected when our lab was taken offline and physically moved across town.

The solution I was going to try is to load a different version of OS because I found that as a possible solution to a similar issue online. But I can't find a link to download the OS.

Am open to try other things if anyone has a different idea.

Thanks!

if write successful, reload and test the device is the config hold as expected.

also test

show run

show start

do you see both the command works as expected.

[marshallkelly]

Show run looks like expected but show start complains.







Router#show start

%% Non-volatile configuration memory has not been set up

[balaji.bandi]

try now copy run start or write memory

[marshallkelly]

I'm scared to get too optimistic but it actually looks like it's working now!



Thanks!

If still an issue format and test it, also google some stable IOS the one was too old.

[marshallkelly]

Well I tried a reload and it lost the config again.

A subsequent write was successful but I tried it again and it is failing again.

I think I may run through the steps you indicated again. Maybe it's just time to replace this one.



Thanks for all your help. I will add an update after I retry - maybe tomorrow.
