The Allied Telesis AT-8350GB is a fast Ethernet switch. The switch features 48 10/100 Ethernet ports and two 10/100/1000 Ethernet ports for speedy networking. Certain security features can only be configured by connecting the switch directly to a terminal using an RS-232 cable. Fortunately, any computer with an RS-232 port and a terminal emulator can configure these features. Changing the switch's username or login password requires a direct connection to the switch and the previous username and password.
Connect one end of the RS-232 cable to the RS-232 port on the back of the Ethernet switch. Connect the other end of the cable to the RS-232 port on the back of your computer.
Start the terminal emulation program on your PC and open the options menu. Consult the help file for your product on how to do this. Enter the following settings on the options menu:
Emulation mode: VT100
Baud rate: 9600
Data bits: 8
Stop bits: 1
Flow control: none
Key mode: Terminal keys
Type in the current username and password to log in to the router. The default username and password are both "manager."
Type "B," then "U" to enter the user interface configuration utility. Type "P" to edit the password or "N" to edit the username. Type the new password or username and press "Enter."
Continue pressing "Q" until you have logged out of the router. Close the terminal emulator and disconnect the RS-232 cable from your computer and the router.
