Resetting to the Default Configuration

Reconfiguration Steps for Boot Block Version 1.01 or Earlier

Follow these steps to reconfigure your access point if the boot block version on your access point is

version 1.01 or earlier and the firmware version on your access point is 11.06 or earlier. To find which

boot block version is on your access point, follow the steps in the “Determining the Boot-Block Version”

section on page 4-5.

Caution Failure to follow these instructions correctly can result in a nonoperational access point that must be

returned to the factory. If your access point stops working after you attempt this procedure, contact Cisco

TAC for assistance.

Step 1 Use a straight-through cable with 9-pin male to 9-pin female connectors to connect the COM 1 or COM

2 port on your computer to the RS-232 port on the access point.

Step 2 Open a terminal-emulation program on your computer.

Note These instructions describe HyperTeminal; other programs are similar.

Step 3 In the Connection Description window, enter a name and select an icon for the connection and click

OK.

Step 4 In the Connect To window, select the port to which the cable is connected and click OK.

Step 5 In the Port Settings window, make the following settings: 9600 baud, 8 data bits, No parity, 1 stop bit,

and Xon/Xoff flow control.

Step 6 Click OK and press Enter three times.

Step 7 When the Summary Status screen appears, reboot the access point by unplugging the power connector

and then plugging it back in, or by pressing Ctrl-X.

Step 8 When the message “Type <esc> within 5 seconds for menu” appears, press Esc.

Step 9 Write down the list of files for future reference.

Caution Perform the next six steps carefully to avoid accidentally deleting the installation key files or the

firmware files. You must carefully note the file selection letters, because they change during the

following steps. If you forget to copy the access point’s installation key file to DRAM in Step 10, or if

you do not copy it back to configuration memory in Step 13, your access point will stop functioning.

Step 10 Copy the access point’s installation key file to the access point’s DRAM by pressing c to select Copy

file, then 1 to select DRAM, then the selection letter for the file called AP Installation Key.

Step 11 If the list of configuration files contains a file called VAR Installation Key, copy that file to DRAM along

with the AP Installation Key. Copy the VAR installation key file to DRAM by pressing c to select Copy

file, then 1 to select DRAM, then the selection letter for the file called VAR Installation Key.

Caution Make sure you select the Configuration memory bank for formatting in Step 12. If you accidentally

format a different memory bank your access point will stop functioning.

Step 12 Reformat the access point’s configuration memory bank by pressing ! to select FORMAT memory

bank, then 2 to select Config, then upper-case Y to confirm the FORMAT command.
