How to Analyze the Intermittent Problem
1. Is a reference code associated with the intermittent problem?
No Yes
↓ Go to “Chapter 2. Unit Reference Codes” on page 59 and find the
reference code. If the actions in the unit reference code tables do not
correct the intermittent problem, return here and continue with the next
step of this procedure.
2. Is a symptom associated with the intermittent problem?
No Yes
↓ Go to “Intermittent Symptom Table”. If the Intermittent Symptom Table
does not correct the intermittent problem, return here and continue
with the next step of this procedure.
3. Go to “Failing Area INT-PIP Table” on page 21. If the Failing Area INT-PIP
Table does not correct the intermittent problem, return here and continue with
the next step of this procedure.
4. Send the data you have collected to your next level of support so that an
Authorized Program Analysis Report (APAR) or a Licensed Internal Code
Trouble Report (LICTR) can be written.
This ends the procedure.
Intermittent Symptom Table
1. In the Symptom column, find the failure symptom.
2. In the Description column, read the description of the failure.
3. In the INT-PIPs column, perform the INT-PIPs shown for that symptom
beginning at “Intermittent Problem Isolation Procedures” on page 332.
Although an INT-PIP may correct the intermittent problem, use your best
judgment to determine if you should perform the remainder of the INT-PIPs
shown for the symptom.
If the symptom for the intermittent problem you have is not listed, go to “Failing
Area INT-PIP Table” on page 21.
Symptom Description INT-PIPs
System becomes
powered off.
The system was operating correctly, then the system became
powered off. SRC 0000 111x may occur when this happens,
but the SRC information is lost if the customer performs an
IPL after the failure and does not record the SRC.
Notes:
1. If the system has no workstation I/O processor cards,
omit INT-PIP5.
2. If the system has an uninterruptable power supply
(UPS), perform “INT-PIP9 Utility Power and Battery
Power Units” on page 336.
“INT-PIP5 External Noise on
Twinaxial Cables” on page 333,
“INT-PIP9 Utility Power and
Battery Power Units” on page 336
System stops. The system is powered on but is not operating correctly. No
SRC or error code is displayed. The System Attention light
is off. The Processor Activity lights may be on or off. Noise
on the power-on reset line can cause the processor to stop.
Note: Ensure that the latest service processor PTF for your
release is installed.
