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.
