On-Line Trouble Shooting

The information is in FAQ format and defines for the most commonly encountered problems a series of steps to isolate the problem.

Questions:

Q. The RSSI LED is OFF.

Q. The TX and RX LEDs are flashing.

Q. The RSSI LED is ON but the TX and RX LEDs are OFF.

Q. The Power LED is OFF.

Q. There is no LINK LED on the Hub (or Switch) Port to which the Air-frame is connected.

Answers:

Q. The RSSI LED is OFF.

A. This indicates that there is no other Air-Frame product in the same Cell Group and in range of this Air-Frame. Verify the following:

  1. The Power LED is ON (if not see the FAQ on this topic).

  2. The antenna cable is securely and correctly connected to your Air-Frame (make sure it is threaded correctly).

  3. The antenna has sufficient power to connect to the remote antenna.

  4. The power loss in the cable connecting the antenna to the Air-frame is not excessive.

  5. You are using the correct (low-loss) cable type to connect the antenna to the Air-Frame.

  6. If the antenna is directional confirm that it is pointed in the right direction and that good line of sight is available.

  7. Confirm that the radio is fully functional by powering on another Air-Frame beside the suspect unit. If the RSSI unit fails to go ON the Air-Frame may be faulty.

Q. The TX and RX LEDs are flashing.

This is normal and indicates that data is being sent and received by the radio interface. If you are not receiving data see the section on ‘Verifying Network Connections’.

Q. The RSSI LED is ON but the TX and RX LEDs are OFF.

This may indicate that no data is being sent or received by the network. Use the ping command defined in the section ‘Verifying Network Connections’ and if this fails read the ping FAQ.

Q. The Power LED is OFF.

A. This indicates there is no power available to the Air-Frame. Verify the following:

  1. The transformer is connected to a power socket.

  2. The transformer is the correct voltage for local conditions (all transformers will work on voltage from 90 to 250V.

  3. The other end is securely connected to the Air-Frame power connector (see Figure-1 (1)). Remove and firmly replace this connector.

  4. There is power available at the wall socket (plug in any equipment that is known to work in the same power socket and confirm that power is available (i.e. the circuit may have fused). If another piece of equipment works in the same power socket then you may have either a faulty transformer or a faulty Air-Frame unit. Contact your local support (see Customer Service section.

Q. There is no LINK LED on the Hub (or Switch) Port to which the Air-Frame is connected.

A. This indicates there is not a good LAN connection between the Air-Frame and your local network. Verify the following:

  1. The Air-Frame Power LED is ON.

  2. Ensure the LAN cable is securely connected to the Air-Frame. Remove and firmly replace the connector (Figure-1 (2)), when the connection is made you should hear an audible click.

  3. Ensure the LAN cable is securely connected to the Hub (or Switch). Remove and firmly replace the connector, when the connection is made you should hear an audible click.

  4. Move the cable at the Hub (or switch) end to another port or if connected to a PC try using a PC that is known to work.

  5. Ensure that you are using a ‘straight’ (uncrossed) cable if the connection is from the Air-Frame to a Hub (or Switch) OR a crossed cable if connection from the Air-Frame directly to a PC (go here for cable pin-outs).

  6. Ensure that the LAN cable is less than 100 meters in length, has no severe kinks, is not damaged and is Category 5 or 5e (Category 3 or ‘silver satin’ cable will NOT provide reliable results).

  7. Use the cable that is currently connecting the Air-Frame to the Hub (or switch) to connect to another device e.g. a PC to the same Hub port. If the Link LED is ON the cable is correct. If the Link LED remains OFF the cable is faulty and should be replaced. Note: In the case of 100M bit/s LANs an equivalent connection should be used for this test. If the Air-frame is operate at 100M then the device which is used for this test MUST be a 100M bit/s connection. A Cable that works at 10M bit/s may NOT work at 100M bit/s.

  8. If all the above fails you may have a faulty Air-Frame unit. See the Customer Service section.
