Convert a 2602i from lightweight to autonomous?

I have a CAP2602i that I would like to convert from lightweight to autonomous.  Is this possible as with the older APs? 

I'm following the instructions for the older models http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html#wp161272 with the adjustment of renaming file ap3g2-k9w7-tar.152-2.JB.tar to ap3g2-k9w7-tar.default.

Here is my console output at the point that I am failing:

process_config_recovery: set IP address and config to default 10.0.0.1

process_config_recovery: image recovery

image_recovery: Download default IOS tar image tftp://255.255.255.255/ap3g2-k9w7

-tar.default

examining image...

DPAA Set for Independent Mode

DPAA_INIT = 0x0

%Error opening tftp://255.255.255.255/ap3g2-k9w7-tar.default (connection timed o

ut)ap:

ap:

The IP address of my PC is set to 10.0.0.2.  The max timeout I can set on my TFTP server is 20 seconds.  Could this be my problem?

Thanks in advance!  Any help would be apprectiated!

Convert a 2602i from lightweight to autonomous?

I was able to get this AP converted from lightweight to autonomous using the following method.

Step 1 Log into the CLI on the controller to which the access point is associated.

Step 2 Enter this command:

config ap tftp-downgrade tftp-server-ip-address filename access-point-name

I still wouldn't mind knowing if there is a doc out there on Cisco.com on the proper steps to convert a 2600 from lightweight to autonomous.  If anyone knows of anything please share.

Otherwise, this has solved my issue for now.

Can someone help me....
I need to switch my 2602e from lightweight to autonomous mode. But I don't have access to the device from the console port.
Is it possible console port be locked using any kind of configuration? I see garbage on my terminal any serial settings I tried. 
Is any familiar with this issue ?

Thanks....

Problem Solved !!!

Although the same roll-over console cable is working fine with all my other Cisco devices it refuses to operate on any 2602x series access point. I use usb to serial converter.
It sounds crazy but it's true. When I switch to other PC and with a different RS-232 rollover cable I had access to my AP at once !!!

I've heard same problem from one more installer who suggested me to switch PC with a real RS-232 port on it.

Convert a 2602i from lightweight to autonomous?

Hello,

I am going to show you the easiest way...


you will need:

-CLI access to the unit

-TFTPd32

-ethernet cable

-dhcp (not really needed)

one you are on the unit..

the process will be:

debug lwapp console cli

debug lwapp client no-reload

archive download-sw /overwrite  tftp://10.0.0.1/c1130-k9w7-tar.124-10b.JDA3.tar

Re: Convert a 2602i from lightweight to autonomous?

Hi Mantej,

It does not work with these new APs 1600/2600.

You need to perform these steps:

  • Restart the Access Point
  • While it loads the image in flash, press Escape, you’ll enter ROMMON mode:

The system boot has been aborted. The following

commands will finish loading the operating system
software:

ether_init

tftp_init

boot

  • Set the IP address for the gigabit 0 interface:

ap: set IP_ADDR 10.0.0.1

ap: set netmask 255.255.255.0

  • Initialize the tftp, ethernet and flash subsystems:

ap: tftp_init

tftp_init success: You can now use tftp file system!

ap: ether_init

Initializing ethernet port 0...

Ethernet speed is 100 Mb - FULL Duplex

ap: flash_init

Initializing Flash...

...The flash is already initialized.

  • Load the image from TFTP and extract it to flash:

ap: tar -xtract tftp://10.0.0.100/ap3g2-k9w7-tar.152-2.JB.tar flash

  • After it’s done, set the correct bootimage:

ap: set BOOT flash://ap3g2-k9w7-mx.152-2.JB/ap3g2-k9w7-xx.152-2.JB

  • Boot the system:

ap: boot

I have 2602i and try to convert LWAPP to Autonomous by

Hi,

Hi,

Console port can't be locked (as fart as I know) , however there is a reset button on the AP. Hold on reset button for 20-30 seconds in order to reset AP.

https://learningnetwork.cisco.com/servlet/JiveServlet/showImage/2-364966-224042/APreset.png

 

if AP is connected to WLC and You have access to WLC, try these commands to convert AP to autonomous mode (as dkleimbach said):

Step 1 Log into the CLI on the controller to which the access point is associated.

Step 2 Enter this command:

 

config ap tftp-downgrade tftp-server-ip-address filename access-point-name

 

 

It happened to own one AIR

It happened to own one AIR-CAP2602E-A-K9 and one AIR-CAP2602E-E-K9.
I purchased both on ebay. On my first attempt to configure the first (A) it was not possible to access the console port. I returned it back and now on my second purchase (E) which is in a very brand new condition I have the same problem with the console access. (My rollover cables are fully tested and functional). It seems that both are somehow configured to block access on console if not, my luck has abandoned me under the thought that both might have defective console ports.

On the other hand, according to
http://www.cisco.com/c/en/us/support/docs/wireless/aironet-1200-series/70278-lap-faq.html
Question: What restrictions are imposed on a Cisco IOS Software-based access point after conversion to lightweight mode?
Answer: APs that are converted to LWAPP provide a read-only console port.

What a read-only console port means? Is this the effect of the problem am I facing?
