About This Book
This section defines the audience of the book, provides general information on
how to use the book, and indicates where you
may find additional information.
Who Should Use This Book
This book is addressed to the service representatives who maintain the IBM
3745 Communication Controllers.
Primary audience: Product Trained (PT) CE
Secondary audience: Product Support Trained (PST) CE, Program Service
Representative (PSR), Product Engineering
(PE)
How To Use This Book
Thjs book describes how the service functions that are specifically for the CE,
and not intended for the customer, are used from the operator console.
Chapter 1 contains the procedure to access the MOSS screen starting from the
initial panel. It also contains general information and the description
of the
machine status area (MSA), common
to all screens.
Some chapters start with a road map. Its purpose is to help the user navigate
in the corresponding part:
1. Select the line corresponding to the action you want to perform.
2. Select the column corresponding to the part of the machine.
The intersection points
to the place where the procedure is described.
The
operator panel procedures are not given in this manual.
Where to Find More Information

tion Procedures (MIP), SY33-2054.

Summary of Changes
The following changes have been made in this book:
• The panels related to the CCU display in the CDF (Chapter 9) have been
modified
to account for a new CCU type.
• The concurrent maintenance (CACM) function has been modified in Chapter
10. Shutdown (SHT) and restore (RST) commands are now the only allowed
commands in service mode.
• The functions related to the Ethernet** adapter have been added. The main
impact is on Chapters 4 (TSS Functions) and 9 (CDF Functions), and to a
lesser extent Chapters 3 (Diagnostics) and 12 (Miscellaneous Functions).
Note: Some panels have been modified to add the new adapter in the pro-
cedures. Depending on
the microcode level of your machine, some
panels may slightly differ from those described but this does not
affect the procedures.
• The layout of the book has been modified to make the procedures easier.
• Quick information retrieval helps have been added at the beginning of the
chapters covering complex functions. They consist mainly in Road Maps,
and synoptics. Road
Maps are dual-entry tables telling you where to go
according to what you want to do and the part of the 3745 you are working
on.
