25. The test indicated that there was no signal from the system. Reconnect the cable you disconnected
and perform the following:
a. Exchange the following parts:
1) Twinaxial workstation IOA card
2) The multi-adapter bridge. See symbolic FRU “MA_BRDG” on page 363.
b. Power on the system to perform an IPL.
This ends the procedure.
26. The tester is in the self-test mode. Check the position of the selector switch:
v If the selector switch is not in the left (1) position, set the switch to the left (1) position. Then go to
step 24 (See page 243).
v
If the selector switch is already in the left (1) position, the port tester is not working correctly.
Exchange the port tester and go to step 23 (See page 243).
27. The cable to the workstation is the failing item. Cable maintenance is a customer responsibility. The
cable must be repaired or exchanged. For information on correcting cable problems, refer to the
Twinaxial cables page in the Plan for hardware and software, Planning reference, Cables topic. For
Cabling instructions, see Print server and rack cabling instructions.Then, power on the system to
perform an IPL.
This ends the procedure.
28. 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.
a. 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.
b. Exchange the following parts:
1) Console
2) Twinaxial workstation IOA
3) The multi-adapter bridge. See symbolic FRU “MA_BRDG” on page 363.
4) Cables
c. If you have another working display, you can exchange the console and perform an IPL to attempt
to correct the problem. See the service information for the failing display for more information.
d. 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 118.
e. The problem may be caused by devices that are attached after the console on port 0.
This ends the procedure.
Workstation adapter PIP
For use by authorized service providers.
This topic contains the procedure necessary to isolate a failure that is detected by the workstation adapter.
This procedure is used when no display is available with which to perform on-line problem analysis.
The workstation adapter detected a problem while communicating with the workstation that is used as the
primary console.
Note: If you are using a PC, you must install an emulation program.
Read all safety procedures before servicing the system. Observe all safety procedures when performing a
procedure. Unless instructed otherwise, always power off the system or expansion tower where the FRU is
located, (see Power on/off the system and logical partitions) before removing, exchanging, or installing a
field-replaceable unit (FRU).
