Recovery Procedures

The Access Point will reboot and the download will begin automatically. You should see downloading activity begin 
after a few seconds within the TFTP server’s status screen.

11.Click OK when prompted that the device has been updated successfully to return to the Scan List screen.
12.Click Cancel to close the ScanTool.
13.When the download process is complete, configure the AP as described in 

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 with a cross-over Ethernet cable.

You must also connect the AP 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.

Before starting, you need to know the Access Point’s IP address, subnet mask, the TFTP Server IP Address, and the AP 
Image file name. Make sure the TFTP server is running and configured to point to the folder containing the image to be 
downloaded.

1. Download the latest software from 

 (Knowledgebase Answer ID 1250). 

2. Copy the latest software updates to your TFTP server’s default directory.
3. Use a straight-through serial cable to connect the Access Point’s serial port to your computer’s serial port.
4. Open your terminal emulation program (like HyperTerminal) and 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

5. Under File > Properties > Settings > ASCII Setup, enable the Send line ends with line feeds option. 

HyperTerminal sends a line return at the end of each line of code.

6. Press the RESET button on the AP. 

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]> 

7. Enter only the following statements:

[Device name]> show (to view configuration parameters and values)
[Device name]> set ipaddrtype static
[Device name]> set ipaddr <Access Point IP Address>
[Device name]> set ipsubmask <IP Mask>
[Device name]> set tftpipaddr <TFTP Server IP Address>
[Device name]> set tftpfilename <AP Image File Name, including file extension>
[Device name]> set ipgw <Gateway IP Address>
[Device name]> show (to confirm your new settings)
