Reloading the Access Point Image
Using the MODE button
You can use the MODE button on 1040, 1100 and 1200 series access points to reload the access point
image file from an active Trivial File Transfer Protocol (TFTP) server on your network or on a PC
connected to the access point Ethernet port.
Note You cannot use the mode button to reload the image file on 350 series access points. To reload the image
file on 350 series access points, follow the instructions in the “Using the CLI” section on page 22-28.
If the wireless device experiences a firmware failure or a corrupt firmware image, indicated by three red
LED indicators, you must reload the image from a connected TFTP server.
Note This process resets all configuration settings to factory defaults, including passwords, WEP keys, the
wireless device IP address, and SSIDs.
Follow these steps to reload the access point image file:
Step 1 The PC you intend to use must be configured with a static IP address in the range of 10.0.0.2 to 10.0.0.30.
Step 2 Make sure that the PC contains the access point image file (such as c1100-k9w7-tar.123-8.JA.tar for an
1040 or 1100 series access point, or c1200-k9w7-tar.123-8.JA.tar for a 1200 series access point) in the
TFTP server folder and that the TFTP server is activated. For additional information, refer to the
“Obtaining the Access Point Image File” and “Obtaining TFTP Server Software” sections.
Step 3 Rename the access point image file in the TFTP server folder. For example, if the image file is
c1100-k9w7-tar.123-8.JA.tar for an 1100 series access point, rename the file to c1100-k9w7-tar.default.
Step 4 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
Step 5 Disconnect power (the power jack for external power or the Ethernet cable for in-line 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 status LED turns red (approximately 20 to 30 seconds), and release the
MODE button.
Step 8 Wait until the access point reboots as indicated by all LEDs turning green followed by the Status LED
blinking green.
Step 9 After the access point reboots, you must reconfigure the access point by using the Web-browser interface
or the CLI.
Using the Web Browser Interface
You can also use the Web browser interface to reload the wireless device image file. The Web browser
interface supports loading the image file using HTTP or TFTP interfaces.
Note Your wireless device configuration does not change when you use the browser to reload the
image file.
