You could either use the mode button approach or the set commands at the ap: prompt:

Re: Installing an OS on a cisco 1200 Aironet AP

This goes way back in my archives but hopefully all you should really need to do is modify it for your TFTP server address and image name.

Follow the steps below to reload the access point image using the CLI. 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 the access point.

Step 1 Open the CLI using a Telnet session or a connection to the access point console port.

Step 2 Reboot the access point by removing power and reapplying power.

Step 3 Let the access point boot until it begins to inflate the image. When you see these lines on the CLI, press Esc:

Loading "flash:/ c1200-k9w7-mx.123-7.JA2/c1200-k9w7-mx.123-7.JA2"....

###########################################################################

Step 4 When the ap: command prompt appears, enter the set command to assign an IP address, subnet mask, and default gateway to the access point.

Your entries might look like this example:

ap: set IP_ADDR 10.0.0.1

ap: set NETMASK 255.255.255.0

ap: set DEFAULT_ROUTER 10.0.0.1

Step 5 Enter the tftp_init command to prepare the access point for TFTP.

ap: tftp_init

Step 6 Enter the tar command to load and inflate the new image from your TFTP server. The command must include this information:

• the -xtract option, which inflates the image when it is loaded

• the IP address of your TFTP server

• the directory on the TFTP server that contains the image, if needed

• the name of the image

• the destination for the image (the access point Flash)

Your entry might look like this example:

ap: tar -xtract tftp://10.0.0.10/c1200-k9w7-mx.123-7.JA2.tar flash:/

Step 7 When the display becomes full the CLI pauses and displays --MORE--. Press the spacebar to continue.

extracting info (229 bytes)

c1200-k9w7-mx.123-7.JA2/ (directory) 0 (bytes)

c1200c1200 c1200-k9w7-mx.123-7.JA2/html/ (directory) 0 (bytes)

extracting c1200-k9w7-mx.123-7.JA2/html/level1/images/apps_button_last_flat.gif (318

bytes)

-- MORE --

If you do not press the spacebar to continue, the process eventually times out and the access point stops inflating the image. Repeat until done inflating the files.

Step 8 Enter 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:/c1200-k9w7-mx.123-7.JA2/c1200-k9w7-mx.123-7.JA

Step 9 Enter the set command to check your bootloader entries.

ap: set

BOOT=flash:/c1200-k9w7-mx.123-7.JA2/c1200-k9w7-mx.123-7.JA2

DEFAULT_ROUTER=10.0.0.1

IP_ADDR=10.0.0.1

NETMASK=255.255.255.0

Step 10 Enter the boot command to reboot the access point. When the access point reboots, it loads the new image.

ap: boot

Step 11 Reconfigure the Access Point.

Good luck!
