This section describes errors, omissions, and changes in user documentation for 340 and 500 series 
bridges and the 4800 series access points.

If you forget the password that allows you to configure the bridge or access point through the console 
port, you might need to completely reset the configuration. Follow these steps to delete the current 
configuration and return all settings to the factory defaults:

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 bridge or access point. You can select the Reset 
option only through the console port.

Open a terminal emulation program on your computer.

These instructions describe HyperTeminal; other programs are similar.

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

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

In the Port Settings window, enter the following settings: 

Bits per second (baud rate): 9600

Data bits: 8

Parity: No parity

Stop bits: 1

Flow control: Xon/Xoff or None

Click OK and press Enter.

When the Main Menu screen appears, reboot the bridge or access point by turning the unit off and then 
turning it back on.

When the bridge or access point reboots and the Main Menu screen reappears, type 2 to select Reset and 
press Enter.

The Reset option appears only if you enable password protection for console write privileges.

Type yes and press Enter to confirm the command.
