Setting IP Address using Serial Port and Normal CLI

Use the following procedure to set an IP Address over the serial port using the normal CLI. The network administrator
typically provides the AP-2500 IP Address.

Hardware and Software Requirements

• Standard serial data (RS-232) cable with a female DB-9 connector at each end (for newer models) or a standard
serial cable and the Mini-DIN8 to DB-9 adapter included in your kit (for older models).
• ASCII Terminal software, such as HyperTerminal.

Attaching the Serial Port Cable

1. Remove power from the AP-2500 and your computer.
2. Connect the serial port cable to the back of the AP-2500 unit and to your computer.
3. Restart the computer and power up the Access Point device.

Initializing the IP Address using Normal CLI

After connecting the serial cable, you may use the CLI to communicate with the AP-2500. You may use most generic
terminal programs, such as HyperTerminal. Once the IP Address has been assigned, use the HTTP Interface or the
CLI to set the AP’s other parameters. Many web sites offer shareware or commercial terminal programs you can
download.
Use the following procedure to initialize the AP’s IP Address.
1. Open your terminal emulator, and then set the following connection properties:
• Com Port: <COM1, COM2, etc., depending on your computer>
• Baud rate: 9600
• Data Bits: 8
• Stop bits: 1
• Flow Control: None
• Parity: None
2. Enable the “ASCII Setup” settings by selecting “Send line ends with line feeds”. Result: HyperTerminal sends a line
return at the end of each line of code.
3. Press the RESET button on the AP-2500 (located on the LED Indicator side of the unit). Result: The terminal
display shows Power On Self Tests (POST) activity, and then displays a CLI prompt, similar to the example below.
This process may take several minutes.
[Device name]> Please enter password:
4. Enter the password (default is "public"). Result: The terminal displays a welcome message and then the CLI
Prompt:
[Device name]>
5. Enter show ip. Result: Network parameters appear:
[Device name]> show ip
