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 reconnect 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
If you observe indications of overload:
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
