Hi,
I have a CISCO 1852 Access Point stuck at (RNAQ-C7) prompt after boot and detecting a nand0 error. Here after the boot log ...
Is it a hardware error ?
If not how to reload a firmware using maintenance link ?
Thanks for your answers.

nand0 is an internal storage component, nothing else but RMA

Do not waste any more time and contact Cisco and organize an RMA.
