Installing Your 3274 Subsystem - IBM 3270 Manual

Device Cable Attachment Forms
A 3274 Device Cable Attachment Form is provided in Appendix B of this
guide to help simplify marking and connecting the cables. Instructions for
completing all portions of the form except Network Addresses and for using
the form are also included in Appendix B. A form should be completed for
each 3274 cluster you order. Copies of the completed form should be given
to the personnel who will install and mark the cables and to the personnel
who will connect the cables to the 3274. In addition, a copy of the form
should be stored in the pocket inside the 327 4 customer access door for
future reference.
Network Address Labels
Hexadecimal address labels (IBM Part 1743290) are delivered with the 3274.
(They will be found, together with an IBM 3274 Control Unit Problem
Report Form, GX23-0203, and IBM 3274 Configuration Data Card
(Configuration Support: A, B, C, T), GA23-0046, in the pocket inside the
3274 customer access door. On the Model 51C they are in the diskette
storage area on the front of the machine.) After each terminal is set up, the
label that specifies the terminal's network address should be attached to the
address label holder on the te.rminal (if present).
It is recommended that a designated.person in your organization (1) obtain
the network addresses from the system programmer, (2) enter the addresses
in the Network Address column ofthe 3274 Device Cable Attachment Form
in Appendix B, and (3) distribute the address information to the person who
will attach the address labels.
For information concerning SNA network addresses, refer to Systems
Network Architecture General Information: Network Addresses, GA27-3102;
for information concerning BSC network addresses, refer to IBM 3270
Information Display System: 3274 Control Unit Description and
Programmer's Guide, GA23-0061.
Installing Your 3274 Subsystem
1-12
When your subsystem arrives and you are ready to install the equipment,
you will need some information that is packaged with the various
components (unpacking instructions, setup instructions, and problem
determination information) and some that will be extracted from this
manual (customizing forms, subsystem verification procedure, color
convergence procedure for the 3279, Printer Authorization Matrix Form,
and Model 31C or 51C switch setting instructions). Some of the forms in
this manual require that you fill in information that is unique to your
installation. It is recommended that you perform your installation in the
following sequence.
