Symptom 1

When the AP is powered on, no information is output on the console port although the serial port of the

PC is connected to the RJ-45 port of the AP.

Analysis

z

If the serial port of the PC is connected to the network port of the AP, no information is output.

z

If the serial port settings are not correct, the serial port works abnormally.

Solution:

z

Check whether the serial port of the PC is connected to the network port of the AP. If yes, connect

the serial port to the port with silkscreen CONSOLE on the AP panel.

z

Check the serial port settings of the PC. The correct port settings should be: 9600 bps baud rate,

no parity check, and 8 data bits.

Symptom 2

When the AP is powered on, it cannot be connected to the network.

Analysis

z

If the network cable is connected to the console port of the AP, the AP cannot be connected to the

network.

z

If the length of the network cable exceeds the specifications (for example, 100 m, or 328.08 ft.), the

AP may not be able to connect to the network.

z

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:

z

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.

z

Replace the network cable with one that meets the specifications.

z

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.
