1230 LWAPP in a real state...no SSC and continuous reloads

BRYN JONES · ‎08-11-2009

Hello

I have a real puzzle here:

We have around 30 1231 LWAPP AP that have been removed from the network when we ran 4.2.61.0.

The flash was cleared of config files and the en_vars file. We are now trying to redeploy them on the netowrk, which is now running 5.2.178.0.

However, we had a failure of one AP upon install and when testing a second on the desk, I see the following on the console:

*Mar 1 00:00:05.351: %SYS-5-RESTART: System restarted --

It appears to me that the SSC is missing and I need to regenerate one but I cannot find any documents telling if it is possible and how to do it.

Is anyone able to comment or provide some light onto how I may be able to rectify this problem?

I would convert them back to autonomous and then back to CAPWAP with the upgrade tool. This loads a new certificate automatically.

Thanks Dennis...I think you are right. After this post, I started doing further research into how to achieve this and cam across this, which has taken the AP back to IOS. I can now run the conversion tool again. Thsanks.

Do connect the AP directly to your PC not the Router.

The best way to do this is to console into the AP and then make sure the

AP can reach the laptop either through a switch or a crossover cable

directly attaching the laptop and AP.

With your console cable, you will be able to see if you have pressed the

button for 20 seconds.

Using a TFTP Server to Return to a Previous Release

Follow these steps to revert from LWAPP mode to autonomous mode by

loading a Cisco IOS release using a TFTP server:

Step 1 The static IP address of the PC on which your TFTP server

software runs should be between 10.0.0.2 and 10.0.0.30.

Step 2 Make sure that the PC contains the access point image file (such

as c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the

TFTP server folder and that the TFTP server is activated. Monitor the

TFTP program to see the code transfer to the AP.

Step 3 Rename the access point image file in the TFTP server folder to

c1200-k9w7-tar.default for a 1200 series access point,

c1130-k9w7-tar.default for an 1130 series access point, and

c1240-k9w7-tar.default for a 1240 series access point.

Step 4 Connect the PC to the access point using a Category 5 (CAT5)

Ethernet cable. This needs to be a crossover cable if directly connected

to the AP. Or normal ethernet cable if the AP and laptop are connected

to a switch.

Step 5 Disconnect power from the access point.

Step 6 Press and hold MODE while you reconnect power to the access

point.

Step 7 Hold the MODE button until the status LED turns red

(approximately 20 to 30 seconds) and then release.

Step 8 Wait until the access point reboots, as indicated by all LEDs

turning green followed by the Status LED blinking green.

Step 9 After the access point reboots, reconfigure it using the GUI or

the CLI.

If the image doesnt download from your pc's tftp server, you may need to delete the previous tar image on the AP from the console:

Just hold the mode button until the LED is red.

Then, using the console port, make sure the prompt is AP: and do a "show

flash:" on the device and make sure that there is no image that starts

"c1130-rcvk9w8-tar...". If there is an image that starts with that then

delete it with "delete flash:
