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.

1-1. INTRODUCTION
'!'his section describes the functional and physical character-
istics of the HP 30010A Intelligent Network Processor (INP) shewn
in figure 1-1. Related publications that may be required for
operation and service of the !NP are listed in the Preface.
1-2. GENERAL DESCRIPTION
'IhE· HP 30010A Intelligent Network Processor (frequently referred
tc hereafter as the !NP) provides the HP 3000 Series II and
Series III Corr.puter Systerr.s with data ccmmunication capabilities
in high-speed as well as low-speed mcdem environments.
A microprccessor within the !NP performs the communications
protocol rnanagemer.t, thus relieving the HP 3000 processor of that
task. As power is applied, the !NP initializes itself, runs a
mini-diagnostic routine, reports to the system that it is
functionally operational, and requests configuration parameters.
Wher: a reque·st for data communication performance is made (for
example, when a user at a terminal opens a DS line), the systerr:
loads the appropriate driver onto the INP. The INP then
t'ransfers control to the driver from its background loader pro-
gram. The driver opens the communications channel and passes.
buffered data back and forth between the HP 300C CPU and the data
cornmunicat ion channel.
Seri al iza t ion , p rotoccl management, fr a me/block management, modem
management, and data buffering are all performed by the !NP. The
CPL must still process message formats and higher level link pro-
cedures. While the !NP is transferring the last correctly
received block of data to the CPU, the !NP is also processing and
buffering the next block of data ccming frcrn the corr,rrunication
channel.

Gener2, 1 Information
Although a complete INP subsystem must include one or more
!NP-to-modem cables, INP-to-INP direct-connect cables, or
INP-to-SSLC direct-connect cables, these cables are not includeJ
under the HP 30010A product number. Each interconnecting cable
or set of cables required for the various configurations is
ocrleced separately under its own product numbe~o See table 1-1
for a list of the available cables.

in s ~H~ ct in q ,
Intelligent
E-; xi E: ting HP
If the IHP printed circuit assemblies (PCAs) and associated cable
asserablies are received separately from the computer system,
inspect the carton containing the items before opening. If there I
is evidence of external damage to the carton, notify the nearest
HP Sales and Service Office and request that the carrier's agent
be present when the carton is opened.
Inq;t:'CL each iterr, as the carton is unpacked. If tbe PCAs or the
cable asseretlies are damaged or fail to meet specifications,
Gctify the corrier and the nearest EP Sales and Service Office
imTuediately. Retain the shipping carton and packing material for
the carrier's inspection. The HP Sales and Service Office will
arrange for repair or replacement of the damaged iterr without
waiting for any claims against the carrier to be settled.
2-2. PREPARATION FOR INSTALLATION
Before beginning any INP installation activities, ensure that the
system operator has backed up the systerr. files. This precaution
will prevent the possible inadvertent loss of the data residing
or. the disk.
