Chapter 4 Troubleshooting 1240AG Series Lightweight Access Points
Returning the Lightweight Access Point to Autonomous Mode
Returning the Lightweight Access Point to Autonomous Mode
You can return a lightweight access point to autonomous mode by loading a Cisco IOS release that
supports autonomous mode (such as Cisco IOS Release 12.3(7)JA or earlier). If the access point is
associated to a controller, you can use the controller to load the Cisco IOS release (refer to your
controller documentation). If the access point is not associated to a controller, you can load the Cisco
IOS release using TFTP.
Using a Controller to Return the Access Point to Autonomous Mode
Follow these steps to return a lightweight access point to autonomous mode using a controller:
Step 1 Log into the CLI on the controller to which the access point is associated and enter this command:
config ap tftp-downgrade
tftp-server-ip-address filename access-point-name
(where:
a)
tftp-server-ip-address is the IP address of the TFTP server
b)
filename is the full path and filename of the access point image file, such as
D:/Images/
c1240-k9w7-tar.123-7.JA.tar
c)
access-point-name is the name that identifies the access point on the
ocntroller.)
Step 2 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED
blinking green.
Step 3 After the access point reboots, reconfigure it using the access point GUI or the CLI.
Using the MODE Button to Return the Access Point to Autonomous Mode
Follow these steps to return a lightweight access point to autonomous mode using the access point MODE
button and a TFTP server:
Note The access point MODE button is enabled by default, but you need to verify that the MODE button is
enabled (see the “MODE Button Setting” section on page 4-10).
Step 1 Set the static IP address of the PC on which your TFTP server software runs to an address 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 c1240-k9w7-tar.123-7.JA.tar for a
1240 series access point) in the TFTP server folder and that the TFTP server is activated.
Step 3 Rename the access point image file in the TFTP server folder to c1240-k9w7-tar.default.
Step 4 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
Step 5 Disconnect power from the access point.
Step 6 Press and hold the MODE button while you reconnect power to the access point.
Step 7 Hold the MODE button until the Radio LED turns red (approximately 20 to 30 seconds) and then
release.
