If the network cable is neither a straight-through nor a cross-over cable, the AP may
not be able to connect to the network.
Solution
If the network cable is connected to the console port of the AP, connect it to the
network port by referencing the Installation Guide of the AP.
Replace the network cable with one that meets the specifications.
Replace the network cable with a standard network cable.
Symptom 3
When a power adapter and a PoE-MH are used to supply power to the AP through the
network port, the AP cannot be powered on.
Analysis
Except the power interface for the power adapter, the PoE-MH has two RJ-45 ports, with
one (# 1) at the same side as the power interface, and the other (# 2) on the other side.
The network cable for power supply should be plugged into RJ-45 # 2. If it is plugged into
RJ-45 # 1, power cannot be supplied to the AP.
Solution
Plug the network cable for power supply into the correct port of the PoE-MH.
Symptom 4
The optical interface of the AP cannot be connected to the network, and the output is
abnormal on the serial port.
Analysis
If you insert an optical transceiver with its upside down, short circuit of clock signals will
occur, and the system will work abnormally.
Solution
Restart the AP and make sure that the optical transceiver is plugged into the AP in a
right direction.
