Troubleshooting
Recovery Procedures
The most common installation problems relate to IP Addressing. For example, without the TFTP server IP address,
you will not be able to download an AP Image to the AP-2500. 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-2500 to default values. The
Reset to Factory Default
Procedure resets configuration settings, but does not change the current AP Image.
If the AP-2500 has a corrupted software image, follow the Forced Reload Procedure to erase the current AP Image
and download a new image.
Reset to Factory Default Procedure
Use this procedure to reset the network configuration values to factory defaults. The current AP Image is not deleted.
This procedure may be required if the AP’s password is lost or forgotten.
1. Press and hold the
RELOAD button for about 10 seconds. Result: The AP-2500 reboots, and the factory default
network values are restored.
2. Use the ScanTool or normal CLI to set the IP Address. See Using the Command Line Interface for CLI information.
Forced Reload Procedure
Use this procedure to erase the current AP Image and download a new AP Image. In some cases, specifically when a
missing or corrupted AP Image prevents successful booting, you may need to use ScanTool or the Bootloader CLI to
download a new executable AP Image.
NOTE
This does not delete the AP’s configuration (in other words, the Forced Reload Procedure does not reset to
device to factory defaults). If you need to force the AP to the factory default state after loading a new AP
image, use the
Reset to Factory Default Procedure above.
For this procedure, you will first erase the AP Image currently installed on the unit and then use either ScanTool or the
Bootloader CLI (over the serial port) to set the IP address and download a new AP Image. Follow these steps:
1. While the unit is running, press the RESET button.
Result: The AP reboots and the indicators begin to flash.
CAUTION
!
By completing Step 2, the firmware in the AP will be erased. You will need an Ethernet connection, a TFTP
server, and a serial cable (if using the Bootloader CLI) to reload firmware.
2. Press and hold the RELOAD button for about 20 seconds until the POWER LED turns amber.
Result: The AP deletes the current AP Image.
3. Follow one of the procedures below to load a new AP Image to the Access Point:
– Download a New Image Using ScanTool
– Download a New Image Using the Bootloader CLI
Download a New Image Using ScanTool
To download the AP Image, you will need an Ethernet connection to the computer on which the TFTP server resides
and to a computer that is running ScanTool (this is either two separate computers connected to the same network or a
single computer running both programs).
ScanTool detects if an Access Point does not have a valid software image installed. In this case, the TFTP Server and
Image File Name parameters are enabled in the ScanTool’s Change screen so you can download a new image to the
unit. (These fields are grayed out if ScanTool does not detect a software image problem.)
Preparing to Download the 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.
