Problem after formating flash wlc 2504

Lujohny18 — Sun, 04 Jul 2021 06:16:53 GMT

Hi people! I had problems with updating the WLC image from 7.0 to 7.2, and made a BIG mistake... I had formatted the flash. So now i do not have RTOS installed on my WLC. The only thing i have is the bootloader 1.0.16. Of course i can not install the code file (*.aes). I think that i need a RTOS to install first? but where can i get one for this device??? Or may be i can install any of RTOS from openwrt (for example) just to enter a normal command line or web GUI, after what i could install (upgrade) the normal .aes image. Please give some sugestions, what to do. Thank you!

You will have to open a TAC case and the engineer can walk you through putting the image back on the WLC.

Thanks for the reply. Already done. Problem was fixed. Cisco engineer gave me the rtos for wlc 5500 and it fixed my wlc!

Dear Ivan,

What is the RTOS software?

Is it the same as the WLC controller software?

Does the name appear as below?

AIR-CT2500-K9-7-3-112-0.aes

After RTOS they will ask for the RF file... what is that?

Did you also update an AP image? Did you use TFTP or FTP for this?

Sorry for the million question but having the same problem and very hard to get support from Cisco TAC.

The rtos image is an image from Cisco TAC. That image you posted is the WLC software image not the rtos. If you can't boot your WLC then you need to have the rtos image and the process on uploading it from TAC.

Hi Scott.

Thanks for your response. I will try TAC again and see if I can gain access for the RTOS software. Is that all that I require? I have a copy of the WLC controller software in case you are wandering.

That is all that is required. TAC will be able to provide that and walk you through the process.

You have another post out there for the same issue. I would just follow up with that one.

You need to RMA the WLC or else opened a TAC case.

Slim chance that you'll see this but I have to try...

I have the same issue. Do you by chance still have the RTOS?

Brad,

Leo Laohoo — Sun, 08 May 2016 03:43:56 GMT

Brad,

Contact Cisco TAC and they'll provide the link to the RTOS. Otherwise, contact anyone from the WNBU.

I too have this same issue.

jwinters99 — Fri, 16 Sep 2016 17:25:05 GMT

I too have this same issue. My main problem is that my wlc is not under a contract and its a lab wlc. I cant open a tac case on it. Is there anyway you could provide the RTOS for 2504? Im kinda stuck here with a dead box.

Thanks!

If you have the exact same

Brad Ellis — Mon, 19 Sep 2016 13:35:05 GMT

If you have the exact same problem you'll need to RMA the device.

I ended up talking to TAC and internal teams to recover the device and in the end it wasn't recoverable - had to have it replaced by my lab support team.

Did u get it solved winters?

khorheesoo — Mon, 19 Sep 2016 14:06:19 GMT

No. I have no way of opening

jwinters99 — Wed, 05 Oct 2016 22:38:32 GMT

No. I have no way of opening a TAC case since the 2504 is out of warranty and I dont have smart-net on it. this is just a lab controller that i used for testing. I would love to be able to get it back up and running but at this point I'm stuck. If there is anyway to get the RTOS files that would be awesome!

Dave,

Contact Cisco TAC and they'll publish the file for you.

Dave Jenkins — Fri, 12 May 2017 15:58:26 GMT

I've tried that, but there is no service contract on my device.

Have you, or anyone, else had luck getting them to provide it in this case?

Or, has anyone done this process and still has the file?
