VLAN Workgroups
The correct VLAN assignment can be verified by pinging the AP to ensure connectivity, by pinging the switch to ensure
VLAN properties, and by pinging hosts past the switch to confirm the switch is functional. Ultimately, traffic can be
“sniffed” on the Ethernet or WDS interfaces (if configured) using third-party packages. Most problems can be avoided by
ensuring that 802.1Q compliant VLAN tags containing the proper VLAN ID have been inserted in the bridged frames. The
VLAN ID in the header should correspond to the user’s assigned network name.
What if network traffic is being directed to a nonexistent host?
• All sessions are disconnected, traffic is lost, and a Forced Reload is necessary.
• Workaround: you can configure the switch to mimic the nonexistent host.
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 Forced Reload is necessary.
CAUTION: The Forced Reload procedure disconnects all users and resets all values to factory defaults.
There Is No Data Link
1. Verify that the indicator for the port is “on.”
2. Verify that the PoE 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 PoE 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 PoE hub or a bad RJ-45 connection.
“Overload” Indications
1. Verify that you are not using a cross-over cable between the PoE 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 (remember to move the input port accordingly); 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 Soft Reset to Factory Default and
Hard Reset to Factory Default procedures reset configuration settings, but do not change the current AP Image.
If the AP has a corrupted software image, follow the Forced Reload procedure to erase the current AP Image and
download a new image.
Soft Reset to Factory Defaults
Use this procedure to reset the network configuration values, including the password, IP address, and subnet mask. The
current AP Image is not deleted.
1. Click Commands > Reset.
2. Click Reset to Factory Default; the device is reset to its factory default state.
