can i have the RTOS file becuase i am facing the dtl driver not initited issue due to crash,
the main thing is we dont have service contract for this.
If it is a software problem(bug), reloading the WLC should work. If not, try Clear Configuration.
If none of these solve the problem, there may be a hardware problem.
Where can AS_5500_RTOS-7.0.250.0 and AS_5500_RTOS-7.0.250.0 be downloaded? My WLC will not boot and the primary and backup images are 6.0.196.0. I’ve see it posted that RTOS is part of AIR-CT5500-K9-1-9-0-0-FUS.aes. Is there a way to extract those files from the aes file? I have another working 5508, is there a way to extract the files from that WLC? Thanks
You need to contact TAC to get RTOS images, or files shared by others on the Internet.
I found the file in Telegram file search ..and it works well.
Regards,
can you please share a link ?
Couldn’t find it on TG…
Thanks in advance
