Chapter 3 Troubleshooting 1240AG Series Autonomous Access Points
Reloading the Access Point Image
Step 7 Click the Reset to Defaults button.
Note If the access point is configured with a static IP address, the IP address does not change.
Step 8 After the access point reboots, you must reconfigure the access point by using the Web browser interface,
the Telnet interface, or Cisco IOS commands.
Reloading the Access Point Image
If your access point has a firmware failure, you must reload the complete access point image file using
the Web browser interface or by using the MODE button. You can use the browser interface if the access
point firmware is still fully operational and you want to upgrade the firmware image. However, you can
use the MODE button when the access point has a corrupt firmware image.
Using the MODE Button
You can use the MODE button on the access point 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 If your access point experiences a firmware failure or a corrupt firmware image, indicated by the Status
LED turning an amber color, 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
access point 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 same subnet as the access
point.
Step 2 Place a copy of the access point image file (such as c1240-k9w7-tar.123-8.JA.tar) into the TFTP server
folder on your PC. For additional information, refer to the
“Obtaining the Access Point Image File” and
“Obtaining the TFTP Server Software” sections.
Step 3 Rename the access point image file in the TFTP server folder to c1240-k9w7-tar.default.
Step 4 Activate the TFTP server.
Step 5 If using in-line power, use a Category 5 (CAT5) Ethernet cable to connect your PC to the To Network
Ethernet connector on the power injector.
Step 6 Disconnect power (the power jack for external power or the Ethernet cable for in-line power) from the
access point.
Step 7 Press and hold the MODE button while you reconnect power to the access point.
