Troubleshooting
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.
Result: HyperTerminal sends a line return at the end of each line of code.
6. Press the
RESET
button on the AP.
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]>
7. Enter only the following statements:
[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 ip
(to confirm your new settings)
[Device name]>
show tftp
(to confirm your new settings)
[Device name]>
reboot 0
Example:
[Device name]>
set ipaddrtype static
[Device name]>
set ipaddr 10.0.0.12
[Device name]>
set ipsubmask 255.255.255.0
[Device name]>
set tftpipaddr 10.0.0.20
[Device name]>
set tftpfilename MyImage.bin
[Device name]>
set ipgw 10.0.0.30
[Device name]>
show ip
[Device name]>
show tftp
[Device name]>
reboot 0
Result: The AP will reboot and then download the image file. You should see downloading activity begin after a few
seconds within the TFTP server’s status screen.
8. When the download process is complete, reset the AP to factory defaults (see
Reset to Factory Default Procedure
)
and configure the AP settings or download configuration files to the AP that you saved as a back-up previously.
