Hello,

smem ram ptable found: ver: 1 len: 3

I looked into it but i can not find a solution. I hope someone here can help me.

Best regards

 - Could be related to them running a bad software version but since they are new I would engage on that with TAC and or ask Cisco for an explanation.

As far as i know my Chef has buyed them used so there is a possibility that they are running a bad Version. But i cant really figure out how i can upload a new or better version to them. With the Command "dhcp" in "btldr" i have no clue what the AP tries to attemp. And "tftpboot" downloads the image only to the address-offset 8800000. But i dont know how to go further from there.

So at the moment i dont know what to do, rather then send them back to the seller.

If there is still a working image on the AP, this here should help:

You can try to boot the part2 instead of part1. If there is also no image, then I don't have a ready solution for you.

Finally i made it Start an Image but now im left with these Messages:

Does somebody know what i have to do now?

[marce1000 · Accepted solution]

 - The situation does not seem that different from your initial post , answers from me and patoberti still apply, did the seller sold you something brand-new or used-already, you need to look at  the integrity of both vendor and what was sold to you.

 M.

[Rich R]

Sounds like somebody sold you faulty APs - return for a refund unless they can get them fixed for you.

[tidope90]

I am going to find out if I should buy a provider contract as I spent too much money and time on the lab and absolutely don't want to throw it away to get air rifle.

Just out of curiosity, does TAC use the flash power that came with APIC to repair the APIC signature? If not, what is the motive of that flash power?

[patoberli]

This is probably unknown what TAC exactly does. I assume they have a way to
reimage those devices if they have corrupt signatures, but for us customers
it's typically RMA.
