PREFACE
This uanual contains installation and servicing information for
the HP 30010A Intelligent l~etwork Processor (IHP). The INP is a
functionally flexible, single-channel data processor that
provides I/O capability between the HP 3000 Series II or Series
III Computer System and other computer systems via either
modulator/demodulators (modems) and telephone lines or direct
connection.
~his manual was written with the assumption that the reader has a
thorough knowledge of the HP 3000 Series II/III I/O system and is
familiar with the latest data communications techniques.
rrhis manual is organized as follows:
Section I, General Information, briefly describes the main
features of the INP and how it operates. This section also
describes how the INP is configured in the computer system,
lists the equipment supplied with the INP, and lists its
specifications.
Section II, Installation, contains instructions for installing
the INP printed circuit assemblies (PCAs) and their inter-
connecting cabling into an HP 3000 Series II or Series III
Coraputer System.
Section III, Programming Information, states the fact that the
INP is preprogrammed and requires no field programming.
Section IV, Principles of Operation, is a description of the
hardware operation of the INP and its associated communication
channels. Since this is a brief overview, intended only to
give the user a better understanding of how the INP does its
job, some minor operational details have been omitted.
Section V, i'1aintenance, contains general servicing infor-
mation, troubleshooting procedures, repair instructions, and a
description of applicable maintenance aids.
This manual should be retained and used with related documen-
tation for the HP 3000 Series II/III Computer System and !NP.
