IBM 3174 Introduction

3174Model1R
3174 Model11R
The 3174 Model 1 R is a large-cluster controller designed for remote operations. It
contains a Type 1 Communication Adapter that provides EIA 232D/CCITT V.24 and
CCITT V.35 interfaces for SNA/SDLC, BSC, or X.25 remote link attachment. The
Model 1 R has 1
MB base storage and one 5-1/4-inch, 1.2MB, high-capacity diskette
drive.
If the controller has one diskette drive and uses devices that require
downstream load microcode, a second diskette
drive or fixed disk must be
installed. A four-port terminal adapter that attaches IBM 3299 Terminal
Multiplexers and Terminal Multiplexer Adapters supports a maximum of thirty two
3270 terminals and 24 ASCII terminals.
Customizing is performed with a control unit
terminal attached to port 0 of the 3174.
Any
terminal can be attached to port 0 at other times. The Model 1 R supports full
keyboard utilities.
Subsystem
online tests and problem determination are performed through a
control unit
terminal attached to any port or multiplexer. Online tests and problem
determination can be done without interrupting other terminals attached to the
controller. Offline tests are performed through the 3174 control panel or through a
control
unit terminal attached to port 0 only.
Features that the
customer can install on the Model 1 Rare:
Second diskette drive
Token-Ring Network Gateway feature
Asynchronous Emulation Adapter
20MB Fixed Disk Drive
Concurrent Communication Adapter
(see note)
Terminal Multiplexer Adapter
Storage Expansion
Encrypt/Decrypt Adapter
Type 3 Communication Adapter
Type 3A Communication Adapter.
Note: If you want to install the Concurrent Communication Adapter on this
controller model, you must replace the 1.2MB diskette drive with a 2.4MB
diskette
drive or a fixed disk and have Configuration Support-B.
The 3174 Model
11 R is a large-cluster controller designed for remote operations. It
contains a Type 1 Communication Adapter that provides EIA 232D/CCITT V.24 and
CCITT V.35 interfaces for SNA/SDLC, BSC, or X.25 remote link attachment. It has
2MB of base
storage and one 5-1/4-inch, high-capacity diskette drive. If this
controller is shipped with Configuration Support-A or -S, Release 5, the diskette
drive is 1.2MB. If the controller is shipped with Configuration Support-B, the drive
is 2.4MB. If the controller has one diskette drive and uses devices that require
downstream load microcode, a second diskette drive or fixed disk must be
installed.
A four-port terminal adapter that attaches IBM 3299 Terminal Multiplexers and
Terminal Multiplexer Adapters supports a maximum of thirty two 3270 terminals
and 24 ASCII terminals.
Customizing is performed with a control unit terminal attached to port 0 of the 3174.
Any
