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 – 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.
