Introduction

This section helps you locate problems related to AP-3 setup. The most common installation problems relate to IP Addressing. For example, without the TFTP server IP Address, you will not be able to download the AP Image to the AP-3.

IP Address management is fundamental. We suggest you create a chart to document and validate the IP addresses for your system.

If the password is lost or forgotten, you will need to reset the AP-3 to default values. The Reset to Factory Default procedure resets configuration settings, but does not change the current AP Image. The Forced Reload procedure erases the current AP Image if you need to download a new image.

It is useful to set up the serial port and use your terminal emulator to monitor AP-3 activity.

Reset to Factory Default procedure

Use this procedure to reset the network configuration values, including the AP-3 IP Address, Subnet Mask, and so on. The current AP Image is not deleted. This procedure may required if the AP-3 password is forgotten.

  1. Press and hold the RELOAD button for about 10 seconds. Result: The AP-3 reboots, and the factory default network values are restored.
  2. If not using DHCP, use the Scan Tool or normal CLI to set the AP-3 IP Address, Subnet Mask, and so on. Please refer to the "Command Line Interface Reference Manual" for CLI information.

Forced Reload procedure

Use this procedure to force the AP-3 back to default network configuration values and download a new AP Image. This procedure may be required when the password is forgotten or the current AP Image is missing or corrupted.

In this procedure, use the Bootloader CLI over the serial port to set the IP Address and download a new AP Image.

  1. While the AP Image is running, press the RESET button. Result: The AP-3 reboots and the indicators begin to flash.
By completing Step 2, the firmware in the Avaya AP-3 will be erased. A serial cable will be required to reload firmware.
  1. Press and hold the RELOAD button for about 20 seconds until the POWER LED turns amber. Result: The AP-3 deletes the current AP Image and Configuration files. The Bootloader CLI becomes active. The following procedure describes how to use the Bootloader CLI to assign an IP Address and download a new AP Image.

Initialize the AP-3 using the Bootloader CLI

In some cases, specifically when a bad AP Image prevents successful booting, you may need to use the Bootloader CLI to download a new executable AP Image. If you need to force the AP-3 to factory default state, use the "Forced Reload Procedure" above.

To download the AP Image, you will need an Ethernet connection to the computer on which the TFTP server resides. This can be any computer on the LAN, or connected to the AP-3 with a "crossover" Ethernet cable.

You must also connect the AP-3 to a computer with a standard serial cable and use a terminal client, such as HyperTerminal. From the terminal, enter CLI Commands to set the IP Address and download an AP Image.

Preparing to download the AP Image

Before starting, you need to know the AP-3 IP Address, Subnet Mask, the TFTP Server IP Address, and the AP Image file name. Ensure the TFTP sever is running and configured to point to the folder containing the image to be downloaded.

Download procedure

  1. Connect the computer serial cable to the AP-3 serial port.
  2. Start TFTP Server, and ensure the new AP Image file is in the TFTP directory. In this procedure, TFTP downloads an AP Image to the AP-3.
  3. Open your terminal emulator, set the following connection properties, and then connect.
    • Com Port: <COM1, COM2, etc., depending on your computer>
    • Baud rate: 9600
    • Data Bits: 8
    • Stop bits: 1
    • Flow Control: None
    • Parity: None
  4. 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.
  5. Press the RESET button on the AP-3. Result: The terminal display shows Power On Self Tests (POST) activity. After approximately 30 seconds, a message indicates: Sending Traps to SNMP manager periodically. After this message appears, press the ENTER key repeatedly until the following prompt appears:

[Device name]>

  1. Enter only the following statements.
    1. [Device name]>set ipaddrtype <Access Point IP Address>
    2. [Device name]>set ipsubmask <Subnet Mask>
    3. [Device name]>set ipaddrtype static
    4. [Device name]>set tftpipaddr <TFTP Server IP Address>
    5. [Device name]>set tftpfilename <AP Image File Name>
    6. [Device name]>set ipgw <Gateway IP Address>
    7. [Device name]>reboot 0

Example:

  1. [Device name]>set ipaddrtype 10.0.0.12
  2. [Device name]>set ipsubmask 255.255.255.0
  3. [Device name]>set ipaddrtype static
  4. [Device name]>set tftpipaddr 10.0.0.20
  5. [Device name]>set tftpfilename MyImage
  6. [Device name]>set ipgw 10.0.0.30
  7. [Device name]>reboot 0

Result: The AP-3 will reboot and then download the image file. Observe the TFTP display and you should see downloading activity begin after a few seconds. When downloading has stopped, the AP-3 is ready for configuration, providing the AP-3 IP Address is correct.

  1. Once the AP-3 image is downloaded and you have a valid AP-3 IP Address, configure the AP-3 as described in "Configuration".

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-3 IP Address.

Hardware and software requirements

  • Standard serial data (RS-232) cable with a male DB-9 connector on one end and a female DB-9 connector on the other end.
  • Serial Port Adapter plug to convert DB-9 to Mini-DIN8 (supplied with kit).
  • ASCII Terminal software, such as HyperTerminal.

Attaching the serial port cable

  1. Remove power from the AP-3 and your computer.
  2. Connect the male end of the serial port cable to the Serial Port Adapter, and then plug the Serial Port Adapter into the Mini-DIN8 connector on the back of the AP-3.
  3. Connect the female end of the serial port cable to the computer.
  4. Restart the computer and power up the AP-3.

Initializing the IP Address using normal CLI

After installing the serial port cable, you may use the CLI to communicate with the AP-3. 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 complete configuration. Many web sites offer shareware or commercial terminal programs you can download.

Use the following procedure to initialize the AP-3 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-3 (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 up to 90 seconds.

[Device name]>Please enter password:

  1. Enter the password (default is "public"). Result: The terminal displays a welcome message and then the CLI Prompt:

[Device name]>

  1. Enter show ip. Result: Network parameters appear:

[Device name]> show ip
IP Address: 10.0.0.1
Subnet Mask: 255.0.0.0
Default Router: 10.0.0.1
Default TTL: 64
Address Type: 1

  1. Change the IP Address and other network values using set and reboot CLI commands, similar to the example dialog below (use your own IP Address and Subnet Mask). Result: After each entry the CLI reminds you to reboot; however wait to reboot until all commands have been entered.

[Device name]>set ipaddrtype static

[Device name]>set ipaddr <IP Address>

[Device name]>set ipsubmask <Subnet Mask>

[Device name]>set ipgw <Default Gateway IP Address>

[Device name]>reboot 0

  1. After the AP-3 reboots, verify the new IP Address by reconnecting, and then entering a show ip CLI statement (as in Step 5). Alternatively, you can use the ping network command from networked computers to test the new IP Address.
  2. When the proper IP Address is set, use CLI or the HTTP Interface over the LAN to complete configuration and manage operations.
