How to reload the IOS image on a Cisco AP using the MODE button
If the wireless device has a firmware failure, you must reload the image file using the Web browser interface or on 1100 and 1200 series access points, by pressing and holding the MODE button for around 30 seconds.
However you cannot use the MODE button to reload the AP image file on Cisco 350 series APs. For information on how to reload the AP image file on the Cisco 350 series AP, refer to the instructions in the Using the CLI section of the same document.
This method can be used when the IOS image on the AP is corrupt. When there is a firmware failure all the LEDs on the AP will glow red.
Using the CLI
Follow the steps below to reload the wireless device image using the CLI. When the wireless device 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 wireless device.
Note Your wireless device configuration is not changed when using the CLI to reload the image file.
Step 1 Open the CLI using a Telnet session or a connection to the wireless device console port.
Step 2 Reboot the wireless device by removing power and reapplying power.
Step 3 Let the wireless device boot until it begins to inflate the image. When you see these lines on the CLI, press Esc:
Note If you do not press the spacebar to continue, the process eventually times out and the wireless device stops inflating the image.
Step 8 Enter the set BOOT command to designate the new image as the image that the wireless device uses when it reboots. The wireless device 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 Enter the set command to check your bootloader entries.
Step 10 Enter the boot command to reboot the wireless device. When the wireless device reboots, it loads the new image.
