Can an autonomous 1252 be converted to Lightweight AP?

Answered Question
Feb 10th, 2009

I have incorrectly received a 1252 AP (model number AIR-AP1252AS-E-K9) and was hoping to convert this to a lightweight AP. But in the documentation this device is missing from the list of devices that can be converted.


I am also unable to find an upgrade tool for this model.


Is it possible to convert this device?

Someone on the forum used the latest upgrade tool and siad he was able to convert the 1252 to LWAPP. You can try it or else here are some steps from another member on converting these ap's:


Here is a method to do the conversion.

*Method 1 : ( Mode Button )*

1. Install an external TFTP tool such as tftpd32 tool from http://tftpd32.jounin.net/

2. Assign IP address in the range 10.0.0.2 - .254 ( Ex : 10.0.0.3) to the tftp server (your laptop or pc).

3. Download the IOS to lwapp image onto the tftp's root directory. Use http://www.cisco.com or

4. Rename c1250-rcvk9w8-tar.124-10b.JA3 to c1250-rcvk9w8-tar.default

5. Make sure you set the IP address on the BVI interface of the AP if not set. Set it in the 10.0.0.x range. Default is 10.0.0.1.

6. Connect the Ethernet port on AP to your TFTP Server ( Laptop )

7. Hold the mode button and power off the AP.

8. Power back the AP while continually holding the mode button for 20-30

seconds.


*Method 2 : ( Archive Command )*

1. Install an external TFTP tool such as tftpd32 tool from http://tftpd32.jounin.net/

2. Assign IP address in the range 10.0.0.2 - .254 ( Ex : 10.0.0.3) to the tftp server (your laptop or pc).

5. Connect the Ethernet port on AP to your TFTP Server ( Laptop )

6. On AP, type archive download-sw /overwrite /force-reload tftp:///c1250-rcvk9w8-tar.124-10b.JA3

If you need to manually "prime" the LWAPP:


AP#lwapp ap ip address


AP#lwapp ap ip default-gateway


AP#lwapp ap controller ip address


AP#lwapp ap hostname

Fella5, thanks very much for the prompt and very comprehensive response. I'll give it a try

s-moynihan Thu, 02/12/2009 - 01:49

Hi Fella5, couldn't get method 1 to work but method 2 was successful. AP is now converted and registered to the WLC


Thanks very much for your help


Steve

Glad you got it to work. I will review method 1 to see if there is a typo of some sort.
