Reloading the Access Point Image
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.
Step1 Open the CLI using a connection to the wireless device console port.
Step2 Reboot the wireless device by removing power and reapplying power.
Step3 Let the wireless device boot until it begins to inflate the image. When you see these lines on the CLI,
press Esc:
Loading "flash:/c350-k9w7-mx.v122_13_ja.20031010/c350-k9w7-mx.v122_13_ja.20031010"

Step4 When the ap: command prompt appears, enter the set command to assign an IP address, subnet mask,
and default gateway to the wireless device.
Note You must use upper-case characters when you enter the IP-ADDR, NETMASK, and
DEFAULT_ROUTER options with the set command.
Your entries might look like this example:
ap: set IP_ADDR 192.168.133.160
ap: set NETMASK 255.255.255.0
ap: set DEFAULT_ROUTER 192.168.133.1
Step5 Enter the tftp_init command to prepare the wireless device for TFTP.
ap: tftp_init
Step6 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
the name of the image
the destination for the image (the wireless device Flash)
Your entry might look like this example:
ap: tar -xtract tftp://192.168.130.222/images/ap3g2-k9w7-tar.152-4.JB5.tar flash
