Resetting a Cisco Air Cap 1552E access point to factory defaults!

[Cap-24]

I am trying to reset a Cisco Air Cap 1552 E access point back to it's factory defaults.  I have tried every mode button press and release from what I read online, but nothing is working.  I do not have an option to reset it via a controller.  Can someone suggest what is the right way to do this.  Thanks in advance.

config ap clear-config <AP-Name>

Check this

[Cap-24]

I cannot log onto the access point.

This command from wlc

This Access point has never been connected to our WLC!

 @Cap-24  Try to hold the mode button for more then 30 seconds ,

I have tried all sorts of length of seconds to get this to reset, but nothing seems to be working.  Should I see a message come up in putty session that says it is being reset.  Other options here?  Is it possible to connect it to the WLC without being able to log into it?  At that stage I can probably change the log in?  Thoughts. 

[Mark Elsen]

 - @Cap-24  Do you see anything at all on the putty connection , for instance after a power cycle of the AP ?

Yes you should see something like this:
Button is pressed. Configuration reset activated..
Keep the button pressed for > 20 seconds for full reset
Wait for the button to be released ....
Button pressed for 0 seconds 1 seconds 2 seconds 3 seconds 4 seconds 5 seconds 6 seconds 7 seconds 8 seconds 9 seconds 10 seconds 11 seconds 12 seconds 13 seconds 14 seconds 15 seconds 16 seconds 17 seconds 18 seconds 19 seconds 20 seconds 21 seconds 22 seconds 23 seconds 24 seconds 25 seconds 26 seconds 27 seconds 28 seconds 29 seconds 30 seconds 31 seconds

Yes - you could plug it into the same subnet as the WLC for local broadcast discovery or use DHCP Option 43 to direct it to discover the WLC.  As long as it can join then you will be able to configure it *but* you made no mention of what software version you're running so if not up to date, and correctly configured, you could be affected by some of the field notices below.

[Cap-24]

Putty does show a full boot up of the Access point.  Goes through two bootloaders, flash phase and Capwap discovery.  I don't see the reset button option working for any second amount.  Any other ideas?  

[Mark Elsen]

 - @Cap-24  No direct other ideas , can you show this boot process ?

@Cap-24 

On the 1552E the reset only works if you do it exactly during the power-on self-test. Unplug the DC/power cable, hold the MODE button down, plug the power back in, keep holding for about 45 seconds until the LED turns red, then release. The AP should wipe its config and reboot to factory defaults.

If you just press the button after boot, nothing happens – it has to be done at power-up.

@Stefan Mihajlov  When I pressed the mode button down for 45 sec, just as I was releasing all lights were red. Unfortunately this did not reset the device.

Does it reboot-loop after the boot process (such as after capwap discovery process and failing to find a controller if it has never joined a controller) ?  Or does the boot up process end to a prompt?  This boot process looks familiar, and I had similar reset issues on 1572s and 1562s, but I haven't had luck trying to find my related notes on it...curious, do you have a controller environment, or wanting to set up as a standalone/autonomous, and therefore needing to factory reset, etc?

[Cap-24]

@coolbreeze  I don't think it reboots after it tries to capwap discovery.  It does not end at prompt, unless I press return and get to log in option.  Can I just join this Lightweight Access Point to our Controller.  I have put the MAC address, host name, IP in our WLC. Let me know.
