IBM 3174 Introduction

3174 Model11L
determination can be performed without interrupting other terminals at~ched to
the 3174.
Offline tests are performed through the 3174 control panel or through a
control
unit terminal attached to port 0 only.
The 3174 Model 1L supports several special features that can be installed by the
customer. They are:
Second diskette drive
Token-Ring Network Gateway feature
Asynchronous Emulation
Adapter
20MB Fixed Disk Drive
Type 3 Communication
Adapter
Concurrent Communication Adapter
(see note)
Terminal
Multiplexer Adapter
Storage Expansion
Type 1 Communication
Adapter
Type 2 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 drive and have Configuration Support-B.
The 3174 11 L large-cluster controller is shipped with an S/370-type channel adapter
for local attachment in an SNA or non-SNA environment. It has 2MB base storage
and a 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 and 24 ASCII
terminals.
Customizing is performed with a control unit
terminal attached to port 0 of the
Model
11 L. This controller supports full keyboard utilities.
Subsystem online tests and problem determination are performed through a
control unit
terminal attached to any port or multiplexer without interrupting other
terminals attached to the 3174. Offline tests are performed through the 3174
control panel
or through a control unit terminal attached to port 0 only.
