If the IBM cable system is being used to attach the workstation, see the
following information:
–
IBM Cabling System Planning and Installation Guide , GA27-3361
– Using the IBM Cabling System with Communication Products , GA27-3620
– IBM Cabling System Problem Determination Guide for Twinaxial Applications ,
GA21-9491
v
If the telephone twisted-pair cable is being used to attach the console, see:
–

Twisted-pair Adapter Planning, Installation, and Problem Analysis Guide
,
GA27-3749
v
If a twinaxial cable is being used to attach the console, see:
–
IBM 5250 Information Display System Planning and Site Preparation Guide ,
GA21-9337
– Twinaxial Cabling Troubleshooting Guide , SY31-0703
v
If a link protocol converter is being used to attach the console, see the link
protocol converter service information for problem analysis.
v
The cable must be repaired or exchanged.
Then power on the system to perform an IPL.
This ends the procedure.
31.
The port tester detects most problems, but it does not always detect an
intermittent problem or some cable impedance problems. The tester may
indicate a good condition, although there is a problem with the workstation
IOP card or cables.
v
If the failing display is connected to a link protocol converter, the link
protocol converter is the failing item. See the link protocol converter service
information to correct the problem.
v
Exchange the following parts:
a. Console
b. Twinaxial workstation IOA
c. The multi-adapter bridge (see “MA_BRDG” on page 554.)
d. Cables
v
If you have another working display, you can exchange the console and
perform an IPL to attempt to correct the problem.
v
See the service information for the failing display for more information.
v
If exchanging the failing items did not correct the problem and the
reference code was a 5002, 5082, or 50FF, there may be a Licensed Internal
Code problem. Go to “LIC-PIP3” on page 344.
v
The problem may be caused by devices that are attached after the console
on port 0.
This ends the procedure.
Workstation Adapter PIPs
Overview
This section contains the procedures necessary to isolate a failure that is detected
by the workstation adapter. These procedures are used when no display is
available with which to perform on-line problem analysis.
