INSTRUCTIONS FOR USING THIS GUIDE
Use this guide with the CE Service Codes and I/PAR
Preparation Guide, ZZ60-0375.
•

For problems that need a repair action:
Record the major and minor codes. For logic
cards/cables, go to the page for the board, read
down to the card/cable location, then across to
the major and minor codes. Make a selection
when there are optional devices.
Record the cause code that best describes the
action.
Record the system reference code in the I/PAR
comments section.
Record the problem and action taken in the
CE/CSR Log at the back of this guide.

•

For problems that do not need a repair action:
No trouble found (NTF)-Record the major unit that
you most suspect to be the problem and a minor
unit of 93. If you cannot determine a major unit,
use the major unit under which you spent time
analyzing the problem. Describe the problem in
the 1/ PAR comments section.
Record the system reference code in the i / PAR
comments section.
Customer responsibility (870)-Use only with
service codes 14 and 30.
Record the IProblem and action taken, if any, in the
CE/CSR Log at the back of this guide.

Do NOT Use Major Units
000, 960, and 980

No Trouble Found: When you suspect a communications
problem to be outside System/36, record the major unit
that you most suspect to be the problem and a minor
unit of 93 (see table at right). If you cannot determine a
major unit, use the major unit under which you spent
time analyzing the problem. Record system reference
code(s). if available, and other details in the I/PAR
comments section.
