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!

Thanks you Balaji but that didn't help. Still seeing the issue.

Apologies, i worked on 2511 for more than 15 years now.

I suggest fixing the issue.(not sure if that work, if not we may need to erase NVRAM and startup from scratch - i will guide if the below steps not working)

this is test it able to write :

config t

!

service compress-config

!

boot config flash:

!

end

wr

post the outcome.

[marshallkelly]

No apologies necessary. I've worked with these 2500s or over 20 years. They just work (most of the time).

It didn't like the line -> boot config flash:

but the write was successful
