cisco C9120AXI-E keeps reloding.

One of my 9120 is stuck in an boot loop.

Is there a way to stop it and flashing the Image?

Well unplug it and then try a factory restore. Hold the mode button down for >2@ seconds. The led should flash red.

Does not help. The result is the same!

- The basic startup contains a number of correctable ECC errors , this is worrisome. Whilst they may be correctable, then the basic OS starts with Welcome to Cisco, which is probably grateful but perhaps the native AP-OS, cannot handle these errors as well as the initial-starup-tests. Since the factory reset does not improve the situation, which would be logic if there is a hardware problem then I think it's time to RMA the device.

Hi Mark,

What switch you connecting it to? I have seen issues with C9100s - where I needed to update my switches to latest code.

Also you running in AireOS or C9800?

If you have other AP’s joined with no issues, then open a TAC case and see if they can help or maybe issue an RMA.

No switch connection at all. Just poe adapter.

I agree. This two lines are unusual.
Contact Cisco TAC and arrange for an RMA. If the AP is brand new, contact your vendor and arrange for a DOA.
