Follow the steps below to reload the access point image using CLI on the serial port. When the access point begins to boot, you interrupt the boot process and use boot loader commands to load an image from a TFTP server to replace the image in your access point
Note ï¿¼Your access point configuration is not changed when you use the CLI to reload the image file.
Step 1 ï¿¼Open the CLI using a Telnet session or a connection to the access point console port.
Step 2 ï¿¼Reboot the access point by removing and reapplying power.
Step 3 ï¿¼Let the access point boot until it begins to inflate the image. When you see these lines on the CLI, press Esc:
Step 7 ï¿¼When the display becomes full, the CLI pauses and displays --MORE--. Press the spacebar to continue.
extracting info (229 bytes)
c350-k9w7-mx.122-13.JA1/ (directory) 0 (bytes)
-- MORE --
Note ï¿¼If you do not press the spacebar to continue, the process eventually times out and the access point stops inflating the image.
Step 8 ï¿¼Enter the set BOOT command to designate the new image as the image that the access point uses when it reboots. The access point creates a directory for the image that has the same name as the image, and you must include the directory in the command. Your entry might look like this example:
ap: set BOOT flash:/c350-k9w7-mx.122-13.JA1/c350-k9w7-mx.122-13.JA1
Step 9 ï¿¼Enter the set command to check your bootloader entries.
I have used this process and it does work. It replaces the VXWorks boot loader and image with the IOS boot loader and image.
A word of caoution you can expect a failure so be prepared to follow the recovery proceedue using the serial port. if you have 10 expect one failure. I have always been able to recover with the serial port proceedure.
