Using diagnostic aids for the 7036-P16

Purpose

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

The purpose of this program is to diagnose hardware problems with the 7036-P16, such as bad connectors, faulty electronic components, etc. 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:

1. The 7036-P16 and the AIX host server must be on the same network.
2. The Digi RealPort^® Software for AIX Package must be installed.
3. The user must ensure the problems are not caused by a faulty host server, the network or a device attached to any one of the sixteen (16) system ports.
4. The Diagnostic Program is executed from the AIX host server.
5. Wrap Plug IBM^® part number 43G0928.

7036-P16 diagnostic program capabilities:

1. Wrap data on each of the sixteen (16) system ports
2. Monitor data on each of the sixteen (16) system ports
3. Provide VPD information

How to use the 7036-P16 diagnostic program

1. Login into 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. The user can choose to see the 7036-P16 product information by typing a "D".
7. The user can choose to test an individual tty port on the selected 7036-P16 by pressing Enter.
8. The next screen will present Port-1 of the 7036-P16 that was selected.
9. The user may choose a different tty port by using the cursor keys to either increment or decrement the port number.
10. Once a tty port is selected, the user may choose to one of the following:
    1. Wrap data by typing a "T". If this option is chosen, the user must use wrap plug part number 43G0928. The user must insert the wrap plug into the tty port.
    2. Monitor the data on the selected port by typing a "D".
11. To exit the diagnostic program, press ESC.

General purpose diagnostic procedures, visual inspections:

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 pSeries^® 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.

   At this point the user must resolve the inability to communicate between the 7036-P16 and the host server.

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

   traceroute [7036-P16 IP Address]
