Troubleshooting the AP-4000

Recovery Procedures

I have just configured the Management ID and now I can't manage the AP?
• Check to ensure your password is correct. If your password is incorrect or all inbound packets do NOT have the correct tag, then a
manual override is necessary.
CAUTION
!
The manual override process disconnects all users and resets all values to factory defaults.

Active Ethernet (AE)

The AP Does Not Work

1. Verify that you are using a standard UTP Category 5 cable.
2. Try a different port on the same AE hub (remember to move the input port accordingly) – if it works, there is probably a faulty port or bad
RJ-45 port connection.
3. If possible, try to connect the AP to a different AE hub.
4. Try using a different Ethernet cable – if it works, there is probably a faulty connection over the long cable, or a bad RJ-45 connection.
5. Check power plug and hub.
6. If the Ethernet link goes down, check the cable, cable type, switch, and hub.

There Is No Data Link

1. Verify that the indicator for the port is "on."
2. Verify that the AE hub is connected to the Ethernet network with a good connection.
3. Verify that the Ethernet cable is Category 5 or better and is less than 100 meters (approximately 325 feet) in length from the Ethernet
source to the AP.
4. Try to connect a different device to the same port on the AE hub – if it works and a link is established, there is probably a faulty data link in
the AP.
5. Try to re-connect the AP to a different output port (remember to move the input port accordingly) – if it works, there is probably a faulty
output or input port in the AE hub or a bad RJ-45 connection.

"Overload" Indications

1. Verify that you are not using a cross-over cable between the AE output port and the AP.
2. Verify that there is no short over any of the twisted pair cables.
3. Move the device into a different output port – if it works, there is probably a faulty port or bad RJ-45 connection.
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 a new AP Image to the AP. 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 to default values. The
configuration settings, but does not change the current AP Image.
If the AP has a corrupted software image, follow the

Reset to Factory Default Procedure

Use this procedure to reset the network configuration values, including the Access Point's IP address and subnet mask. The current AP
Image is not deleted. Follow this procedure if you forget the Access Point's password:
1. Press and hold the RELOAD button for 10 seconds.
NOTE
You need to use a pin or the end of a paperclip to press a button.
Result: The AP reboots, and the factory default network values are restored.
2. If not using DHCP, use the ScanTool or use CLI over a serial connection to set the IP address, subnet mask, and other IP parameters.
See Using the Command Line Interface (CLI)
Forced Reload Procedure
for CLI information.
Reset to Factory Default Procedure
to erase the current AP Image and download a new image.
