Local Work Station Network Analysis Procedure - IBM System/36 Maintenance Information Manual

706 Local Work Station Network Analysis Procedure
The system console must be working before this procedure can be used. Also, you need to know the
addresses of the work stations that are attached to the system. The customer should give you this
information.
This procedure uses the network analysis option of the DCP Main menu to isolate local work station
problems. The network analysis option displays a matrix on the system console. The matrix shows:
• The cable and station addresses of all possible work stations across the top of the matrix.
• The conditions sensed for each address down the side of the matrix.
An X is placed at the position of the work station address and the condition that was sensed. The correct
responses are as follows:
• Work station display: An X in the single-frame condition row.
• Work station printer: An X in the single-frame condition row for the first sense and an X in the
multiframe condition row for following senses.
• No work station at the address: An X in the no-response row.
The following FRUs are partially tested:
- AIF2 work station adapter/control panel interface
- AIE2 work station pass-through or work station controller
• Work station controller card (AIE2): The controller card is used only on systems with the work station
expansion feature. (28 local work stations)
• Work station pass-through card (AIE2): The pass-through card is used only on base systems. (16 local
work stations)
• Internal cable to workstation ports.
• Al board
• Twinaxial cables
• Work stations
To run network analysis:
1.
Ensure that the Security switch is in the Service position.
2. Insert diskette 61.
3. Select function 3 (IPL Diskette).
4. Enter 0000.
5. Press the Start Function key.
6. When the DCP Main menu appears on the system console, select the network analysis option.
The system displays a status matrix on the console after approximately 30 seconds.
7. Use the following table and the matrix that is displayed to isolate the failure.
8. To end network analysis, load the system again ("320 Loading the SSP" on page 3-7). Verify that the
system is operating correctly.
