Preface
This manual is intended for the customer personnel in charge of
preparing the integration of an IBM 3720 to a communication
network. It contains step-by-step instructions describing the
system integration tasks.
It is assumed that the 3720 has been setup and checked out
successfu II y.
It is also assumed that you, being in charge of system
integration,
are familiar with communication controllers and
networking.
Technical changes in this edition are denoted by a revision bar to
the left of the changed information.
There are three ways of integrating your 3720:
1. System integration at 3720 first installation, or after
relocation, or after removal of the 3721. Go to page iv.
2. System integration when the 3720 has been upgraded with a
3721. Go to page
v.
3. System integration when the 3720/3721 has been upgraded
with new communication features, or downgraded (cables
and cassettes, or cables only). Go to page vi.
Before you start, read this manual through and ensure that you
have all the
materials required for the appropriate integration
procedure.
Note: Should you have any problem in deciding where to start,
ask your Installation Coordinator.

You do this integration when the 3720/3721 Feature I~ddition Instructions or 3720/3721 Setup Instructions
(or the person carrying out the upgrading or downgrading) request you to update the configuration data file.
You
first update the configuration data file, then perform the other setup and system integration tasks. Therefore, the tasks
are split into two groups: PASS 1 and PASS 2. Perform PASS 1, then return to the Feature Addition Instructions or Setup
Instructions for the remaining setup tasks. Then perform PASS 2 (on next page) when requested to do so in the Feature
Addition Instructions or Setup Instructions.

01
Checking the Worksheets Required for System Integration
If you are integrating when the 3720 is upgraded with a 3721 or
with new communication features, or downgraded, (PASS 1
only), go to STEP
28.
Obtain from your installation coordinator the:
• Requirements Sheet
• IPL Port Sheet
• Console Sheet
• Plugging Sheet
These sheets
were taken from the 3720/3721 Configuration
Guide and
filled out at the configuration stage.
They contain the information required for some of the
integration functions.
Do you have these sheets?
NO Contact your installation
coordinator
YES See below
• If integrating when the 3720 is first installed, or relocated,
or after removal of the 3721, go to STEP 2.
• If integrating when the 3720 is upgraded with a 3721 or with
new communication features, or downgraded,
(PASS 2 only), go to STEP 24.

Attaching Console(s) to your 3720
Before starting, check that:
1. The 3720 has been powered off after the completion of
the setup.
2. The console(s) and/or the modem(s) or data
circuit-terminating equipment (OCEs) to be a.ttached have
been placed on the site and prepared
for attachment
according to their documentation.
3. You obtained a completed Console Sheet and the 3720
keys from your Installation Coordinator.
4. Go to STEP 3.

AHaching Console{s) (Continued)
5. You have received the IBM-supplied cables for local and
remote attachment, and they have been placed on the site
and labeled at both ends according to the 3720/3721
Planning and Site Preparation Guide, GA33-0061.
6. IBM PC local console connection:
You
must attach the IBM PC to the 3720 with a special cable
for local console operation. The cable you should use is an
assembly of two cables, the standard local console cable,
part number 6398736, and a short cable, part number
7837400, which adapts the 3720 local console to the PC
COM1 port.
IBM PC remote console connection:
For
remote console operation, a modem attachment cable
such as the IBM PC communications adapter cable, or an
equivalent V.24/RS232-C cable, must be used to attach the
IBM PC to a modem.
External
modems with a "voice/data" switch should be used
in
preference to PC internal modems for remote console
operation. The IBM PC emulation program cannot switch
between character and block modes automatically. Internal
modems require character mode to receive modem
commands,
while the IBM 3720 only uses block mode.
7. Go to STEP 4.

Using the Console Sheet
The Console Sheet was filled in at the configuration stage.
1. Check that you have the sheet related to your 3720 unit
o·
Check the serial number in Oand ensure that it matches
your 3720.
2. You will use the Console Sheet for attaching the console
later.

SeHing the Required Operating Characteristics for the IBM PC 5150, 5155, 5160, or 5170
1. Hardware requirements:
To use an IBM PC for IBM 3720 MOSS console emulation,
the
PC must have:
• The IBM 3101 Emulation Program
• An asynchronous communications port configured as
COM1 (primary asynchronous adapter).
Refer to the option instructions
for the asynchronous
communication
adapter in the IBM PC Guide to
Operations manual
for information on the installation and
configuration of the adapter.
2. Software requirements:
The 3101 emulation program must be installed and
operational on the IBM
PC. For a description of how to
set up the required communication operations, see the
IBM 3101 Emulation Program manual.

• A local console and you also have an RSF link, read the warning
below, then go to STEP 14.
Warning: Some modems disconnect from the switched network as soon as
the carrier wave drops, so it may be necessary to set the modem at the PC
side of the line to 'RTS Permanent'. Refer to your modem documentation.

Setting the Required Operating Conditions for the IBM 3101
1. If you have an IBM 3101, you must select the required
operating characteristics. '
