The following warning statements (required by country regulatory agencies) are applicable in the countries
indicated.
United States United States
Warning: This
equipment generates, uses, and can radiate radio frequency energy and if not installed and
used
in accordance with the instructions manual may cause interference to radio communications. It has
been tested and found
to comply with the limits for a Class A computing device pursuant to Subpart J of
Part 15 of FCC Rules, which are designed to
provide reasonable protection against such interference when
operated in a
commercial environment. Operation of this equipment in a residential area is likely to cause
interference in which case the
user at his own expense will be required to take whatever measures may be
required
to correct the interference. .
Additional IBM Statement
This warning is also applicable to all attaching units produced
for use in the U.S.A. that have been
manufactured after December
31, 1980. A notice of compliance has been affixed within the customer
access area of all affected units.
Instructions to User:
Properly shielded and grounded cables and connectors must be used
for connection to peripherals in order
to meet FCC emission limits. Proper cables are available through IBM marketing channels, or from
dealers of computer accessories. IBM is not responsible
for any radio or television interference caused by
using
other than recommended cables or by unauthorized modifications to this equipment. It is the
responsibility of the user to correct such interference.
United Kingdom
Warning: This IBM product
is made to high Safety standards. It complies inherently with
Telecommunications safety standard BS6301. It Is not designed to provide protection from excessive
-voltages appearing externally at its interfaces. Therefore, when this product is connected to a public
telecommunications network via any other equipment, and you connect to this product items not supplied
by IBM United Kingdom Ltd., you must comply with mandatory telecommunications safety requirements.
You
may do this either by choosing products which also are approved as complying to BS6301 or British
Telecom Technical Guide No. 26, or by the use of approved safety barriers. Consult the local office of your
public telecommunications operator, for advice and permission to make the connections.
Canadian Department
of Communications compliance statement
This equipment does not exceed Class B
limits per radio noise emissions for digital apparatus, set out in
the Radio Interference Regulation of the Canadian Department of Communications. Operation in a
residential
area may cause unacceptable interference to radio and TV reception requiring the owner or
operator to take whatever steps are necessary to correct the interference.
Avis de conformite aux normes du ministere des Communications du Canada
Cet equipement ne depasse pas les limites de Classe B d'emission de bruits radioelectriques pour les
appareils numeriques, telles que prescrites par Ie Reglement sur Ie brouillage radioelectrique etabli par Ie
ministere des Communications du Canada. L'exploitation faite en milieu residentiel peut entrainer Ie
brouillage des receptions radio et tele, ce qui
obligerait Ie proprietaire ou I'operateur aprendre les
dispositions necessaires pour en
eliminer les causes.

vi 3174 Models 1L, 1R, 2R, 3R, 11L, 11R, 12R, and 13R Maintenance Information

Preface
Preface
This manual identifies the tasks involved in maintaining the IBM 3174 Establishment Controller Models 1L,
1R, 2R, 3R, 11L, 11R, 12R, and 13R and provides the information needed to keep these controllers in, or to
restore them to, good working order.
Who This Book Is For
This book is for the product-trained and support-trained IBM service representative who maintains the 3174
Establishment Controller Models 1 L, 1 R, 2R, 3R, 11 L, 11 R, 12R, and 13R
The maintenance procedures described in this manual represent a part of the overall support structure for
the
3174 Establishment Controller. This support structure,which begins at the 3174 operator level, is
described briefly below.
3174 Operator
The 3174 operator performs initial problem isolation and recording of the 3174 failure indications by
following the procedures in the 3174 User's Guide
or the 3174 Customer Extended Problem Determination
manual. If the problem is other than a customer operating procedure or customer-supplied power, the
operator requests IBM service.
Product-Trained Service Representative
The product-trained service representative performs the maintenance procedures contained in this manual
to isolate a problem to a field replaceable unit (FRU), a communication failure, a data stream problem, an
attached-device failure,
or a specific cause, such as a defective cable. If the maintenance package cannot
isolate
or correct the fault, the product-trained service representative requests assistance from the next
level of the support structure.
Support-Trained Service Representative and Area-Designated Specialist
The support-trained service representative and the area-designated specialist use their in-depth knowledge
of telecommunication and of the product to continue problem determination beyond the scope of the
maintenance manual.

Preface
How This Book Is Organized
This book has six chapters:
Chapter 1, General Information, describes the service representative's maintenance approach to
3174
problem analysis and repair. This chapter also contains examples of 3174 controller configurations, and a
description of models and features, operating procedures, environmental restrictions, and special tools.
Chapter 2, Diagnostic Information, contains symptom charts, maintenance analysis procedures (MAPs),
offline and online tests, general procedures, and 370/0LTs.
Chapter 3, Repair Information, contains locations, card-plugging charts, an interrupt level chart, and
removal and replacement procedures.
Chapter
4, Installation, contains information on how to install the local (channel-attached) model of the
3174, the Models 1
Land 11 L. (The chapter applies to these models only.)
Chapter 5, Safety Inspection Guide, contains some of the information used to determine whether a machine
can be placed on
an IBM maintenance agreement.
Chapter
6, Parts Catalog, contains illustrations and part numbers for the 3174.
The book has three appendixes:
Appendix A contains information about the IBM Cabling System and
3299 Terminal Multiplexer reference
information.
Appendix B contains information about the X.25 feature.
Appendix C contains information about the
X.21 feature.
Abbreviations and terms used in the manual are defined in the back, preceding the Index.
