Using diagnostic aids for the 7036-P16

You might need to use diagnostic programs to identify hardware problems. Use the procedure in this section to perform this task.

The 7036-P16 is not supported under AIX® Diagnostics. A means to diagnose hardware problems with the 7036-P16 is provided by an executable program.

The purpose of this program is to diagnose hardware problems with the 7036-P16, such as bad connectors, faulty electronic components, and so on. The diagnostic is not intended to resolve protocol problems, network problems or a faulty host server to which the 7036-P16 may be attached.

Requirements for using the 7036-P16 diagnostic program

7036-P16 diagnostic program capabilities

Using the 7036-P16 diagnostic program

  1. Log in to the AIX host server as root.
  2. From the root home directory type:

    ./usr/lbin/tty/dpa-ncxa

  3. Press Enter.
  4. The next screen will present a list of all the 7036-P16s configured on the host server. The list includes the device name and the IP Address for each 7036-P16. The user should look at the bottom of the screen for options.
  5. Select a 7036-P16 on the list by using the cursor keys. The 7036-P16 selected is highlighted.
  6. Type D to see the 7036-P16 product information.
  7. Press enter to test an individual terminal type (tty) port on the selected 7036-P16. The next screen will present Port-1 of the 7036-P16 that was selected.
  8. To select a different tty port, use the cursor keys to either increment or decrement the port number.
  9. Once a tty port is selected, then select one of the following items:
    1. Wrap data by typing a T. If this option is chosen, use wrap plug part number 43G0928. Insert the wrap plug into the tty port.
    2. Monitor the data on the selected port by typing a D.
  10. To exit the diagnostic program, press ESC.

General purpose diagnostic procedures, visual inspections

Ethernet cables
  • Ensure an Ethernet cable is attached to the 7036-P16 and the host server.
  • Ensure the Ethernet cable is wired correctly.
  • Ensure the Ethernet cable is good.
Serial cables
  • Ensure a serial cable is attached to every 7036-P16 port that is in use.
  • Ensure the serial cables are wired correctly.
  • Ensure the serial cables are good.

Investigating Ethernet network problems associated with the 7036-P16

  1. Gather the following information:
    For the 7036-P16:
    • MAC Address: [MAC Address] (MAC Address label is on the back of the 7036-P16)
    • IP Address: [7036-P16 IP Address]
    • Default Gateway: [IP Gateway Address]
    • Name Server: [Name Server Address]
    • Host Name: [Host Name] (if a host name is assigned)
    For the host server:
    • Machine Type and Model
    • AIX Level
    • IP Address: [Host server IP Address]
    • Default Gateway: [IP Gateway Address]
    • Name Server: [Name Server Address]
    • Host Name: [Host Name] (if a host name is assigned)
  2. Ping the 7036-P16 from the host server by typing: ping -c 1 [7036-P16 IP Address]

    If the 7036-P16 responds to the ping, then both devices are on the network; the problem is not a network attachment problem. If the ping times out, then either the 7036-P16 or the host server is not on the network.

  3. Use traceroute to see where the link between the 7036-P16 and the host server is broken. Type:

    traceroute [7036-P16 IP Address]
