FN - 63763 - AP1250, AP1140, AP1520, and AP1130 Might Fail to Boot Up after a Software Upgrade or Power Cycle

ANURAJ.R · ‎05-17-2020

i dont understand anything from this link will u pls tell me the exact solution?

@Leo Laohoo

What Leo posted is a possible issue with your device that would require replacement if you have a valid support contract.
Erasing the startup config like you did wouldn’t break your AP. Seems like maybe your ap is failing, that is a very old AP.

ANURAJ.R · ‎05-18-2020

Ohh my goodness.

i dont have a support contract @Scott Fella bro..

Rafael E · ‎05-18-2020

The field notice share above is the problem you are seeing.

You can try recover the AP from rommon, go to rommon and from there format flash and try to load an image with the code fix for the FN.

If above does not work then you do probably need an RMA

Scott Fella · ‎05-18-2020

Yeah… that ap is end of support, so basically it's a paper weight at this point.

We'll need to RMA the device, it's a Hardware issue

These product symptoms are observed:

The AP does not boot
The AP's LEDs are all red
The AP does not respond on its console

Workaround/Solution

Normal SmartNet and warranty entitlement rules remain in place and are applied by the Cisco Technical Assistance Center (TAC) if you experience a failure in one of the products listed in the Field Notice. In other circumstances, such as out of warranty or out of contract, Cisco encourages you to raise your concern directly with your Cisco account team.

Fix on Failure Replacement Guidelines: Request Return Material Authorization (RMA) product through normal service support channels.

If you need assistance in order to determine which hardware part(s) might need replacement, consult the error messages documented in the Problem Symptom section.
