Diagnosing Access Point Indicators

 

Troubleshooting Chart

 

 

Symptom

Action

 

 

Status LED is Off

• External power supply may be disconnected. Check connections between

 

the access point, the power adapter, and the wall outlet.

 

• If using PoE, verify that access point’s RJ-45 port is attached to a PoE

 

source device, that the PoE source device is powered on, and that PoE

 

power is enabled on the port attached to the access point.

 

• Contact Technical Support.

 

 

Link LED is Off

• Verify that the access point and attached device is powered on.

 

• Be sure the cable is plugged into both the access point and corresponding

 

device.

 

• Verify that the proper cable type is used and its length does not exceed

 

specified limits.

 

• Check the cable connections for possible defects. Replace the cable if

 

necessary.

 

 

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

Console Access

If you cannot access the command line interface via a serial port connection, check the following items before you contact Technical Support:

Be sure you have set the terminal emulator program to VT100 compatible, 8 data bits, 1 stop bit, no parity and 9600 bps.

Check that the serial cable conforms to the pin-out connections provided in Appendix B.
