Notice to UK Users
The IBM 3746 Model 900 and IBM 3746 Model 950 are manufactured according to
the International Safety Standard IEC950 and, as such, are approved in the UK
under the General Approval number NS/G/1234/J/100003.
The Active Remote Couplers (ARCs) and the X.21 Interface, housed within the
3746 Model 900 and 3746 Model 950, are approved separately, each having their
own independent approval number. These interface adapters, supplied by IBM, do
not contain excessive voltages. An excessive voltage is one which exceeds 42.4 V
peak ac or 60 V dc. They interface with the 3746 Model 900 or 3746 Model 950,
using Safe Extra Low Voltages only.
In order to maintain the independent approval of the IBM adapters, it is essential
that other optional cards, not supplied by IBM, do not use mains voltages or any
other excessive voltages. Seek advice from a competent engineer before installing
other adapters not supplied by IBM.
Safety
This product meets IBM safety standards.

How This Guide Is Organized
This guide consists of the following chapters and appendixes:
Chapter 1, “General Information on 3745 and 3746 Controllers,”gives an
overview of 3745 and 3746 controllers, with specifics on the controller panel,
and additional pointers on problem solving.
Chapter 2, “Service Processor,”explains the functions of the service processor
and how to connect a service processor to a remote console.
Chapter 3, “Maintenance and Operator Sub-System-Extended (MOSS-E),”
explains how to use MOSS-E and MOSS sessions for the 3746.
Chapter 4, “Working with Network Node Processor (NNP) Functions,”explains
how to access the APPN/HPR control point and IP router functions of the NNP
via the MOSS-E.
Chapter 5, “Telnet IP Resource Management in CCM and MOSS-E,”contains
information on using CCM and the MOSS-E for Telnet commands.
Chapter 6, “Introduction to Remote Access Programs”to Chapter 13, “Using
DCAF with an APPC LAN-Attached Remote Workstation,”explains how to
configure remote consoles that use DCAF to monitor and control the service

Chapter 14, “Telnet-Attached Remote Workstation,”explains how to configure
remote consoles that use Telnet Client program. Access is given to the
network node processor for IP purpose only.
Chapter 15, “Java Console Remote Access”on page 15-1 to Chapter 17,
“Installing the Java Console Program”on page 17-1, describes how to
configure remote workstations using the web-based or Java program-based
