TCP/IP LAN Connection Troubleshooting Procedures

If the Avaya Intuity system fails the TCP/IP send-and-receive packets test, complete the following procedures:


Important! Because the LAN circuit card LEDs are recessed and the surface of the faceplate is reflective, you must look straight at the LEDs for an accurate reading. If you attempt to read the LEDs from a standing position, you may get a false reading. Look closely at the faceplate to determine whether or not the LEDs are lit or flashing.

  1. Check the status of the three green LEDs on the faceplate of the LAN circuit card.
    Link status activity
    Closest to the input jack
    Link connection
    Flickering continuously
    No link connection
    No link connection
    Data activity
    Middle LED
    Data activity
    Idle (No data activity)
    LAN speed
    Furthest from the input jack
    100-MBit LAN cable
    Not a 100-MBit LAN cable
  2. Verify that the circuit card configuration is correct.

    Note: The network interface card type for Release 5 is PRO100B.

  3. Return to Initializing the LAN Circuit Card and reenter the network interface type,
    if necessary.

  4. Verify that the LAN circuit card is recognized by the system. See Viewing Installed Hardware for more information on verifying the LAN circuit card.
  5. Verify the network addresses.

    Note: The TCP/IP interface name for the LAN circuit card supported for Release 5 is eeE_0.

  6. Verify that there are no TCP/IP error messages on the system.
  7. Check the condition of the LAN circuit card LED after you have readministered the network interface type. If the LED is lit, retry the send-and-receive-packets test using the Test IP Address.
  8. If the LED on the LAN circuit card faceplate is not lit, the LAN circuit card, cable, or the hub device may be bad.

  9. Visually inspect the faceplate of the LAN circuit card. The LED on the faceplate should flash if the LAN circuit card is sensing packets on the LAN. On LAN networks, each machine reads all of the packets transmitted to and from other machines on the network, and ignores the packets not addressed directly to that machine. At this stage, the Avaya Intuity system should be sensing packets on the LAN.
  10. If the LED is flashing to indicate that the Avaya Intuity system is sensing packet transmission on the LAN, continue with Step 8.

    If the LED is not flashing, the card may be faulty. Continue with Step 8, and if the LED does not come on, contact your remote support center and replace the LAN circuit card.

  11. Visually inspect the cable and the cable connection. Test the tightness of the connection.
  12. If the connection is tight, continue with Step 9.

    If the connection is loose, tighten the cable and retry the send-and-receive-packets test. If the test fails again, continue with Step 9.

  13. Disconnect the cable and verify that the cable to the LAN is functional.
  14. If the connection is functional, continue with Step 10.

    If the cable to the LAN is not functional, contact the customer LAN administrator or system administrator.

    Important! It is the responsibility of the customer to provide you with a live cable and a suitable connector.

  15. Verify your TCP/IP addressing and circuit card configuration administration. Return to Administering TCP/IP LAN Connectivity and use the procedure listed to display the windows.
  16. If your addressing is correct, press F6 (Choices) to exit from the window without making any changes and continue with Step 11.

    If your addressing or card configuration is not correct, readminister TCP/IP networking using Establishing Network Addresses and Initializing the LAN Circuit Card. Retry the send-and-receive-packets test. If this test fails again, continue with Step 11.

  17. Ask the LAN administrator or the system administrator to verify that the LAN is correctly administered for the Avaya Intuity system. Ask the administrator to verify the Avaya Intuity UNIX name, Internet protocol (IP) address, subnet mask, and default gateway.
  18. If all of the information matches what you have administered on the Avaya Intuity system, continue with Step 13.

    If the information for the Avaya Intuity system was not correctly administered for the LAN, readminister the TCP/IP Networking window and reboot the system. Try the send-and-receive-packets test again.

  19. Diagnose the session layer.
  20. If the send-and-receive-packets test fails after you have readministered and rebooted the Avaya Intuity system, ask the administrator to attempt a PING test to the Avaya Intuity system. If the administrator reports a failure to you but indicates that the customer LAN is operational, contact your remote support center.


    Avaya service technicians dispatched for Avaya Intuity system installation are not responsible for the installation, administration, or test of communications between the customer's personal computers and the LAN. Customers should seek service as directed by their LAN administrator to resolve problems with their LAN
