DESCRIPTION
       The new Micro Channel 370 Models 110, 112 and 114 offer
management functions that make the Micro Channel 370 a superior
application platform where systems management from a System/370 host
site is key.  The doubling of the DASD capacity with the Models 112
and 114 offers more opportunity for customer application growth.
       The Micro Channel 370 models are very adaptable, low priced
System/370 systems particularly suited for distributed and
stand-alone applications solutions in System/370 enterprises.  They
are the low-cost threshold for installation of a System/370
application platform.  The function and price point also make them an
attractive system for business partners who market to non-370 as well
as System/370 enterprises.
       A wide range of optional communication and LAN adapters are
available to support both SNA networks and communication with OEM
systems.  LAN attachments include Token-Ring and Ethernet LANs.  In
addition to support for standard protocols, programmable
communications is available when non-standard communication protocols
are needed.  With the Model 114, System/370-PS/2 (R) BiProcessor
capability is available to meet unique application requirements.
       The Micro Channel 370 can support System/370 workstations and
terminals including, the 5080 engineering displays and 3270-type
displays and printers.  The 3151 displays in 3270 emulation offer a
low-cost display option.  For printing, high-speed laser and impact
channel printers are supported.  For lower-speed printing, 3270
family printers are also supported.  For the lowest-cost printer
option, a selection of PS/2 printers are supported in 3287 emulation
mode.
 (R) Registered trademark of International Business Machines
   Corporation.
       Compared to the original 9371 models, the total integrated
DASD capacity available for the 112 and 114 is doubled.  The new
models have the same compact size as the original 9371 models.  They
have all the capabilities and can use all the adapters available for
the original 9371s.
       Customers with the original Models 010, 012 and 014 may add
many of the new functions by ordering specify code 9001 and feature
#1002.  The doubling of the maximum number of integrated DASD on the
Models 112 and 114, the consoleless option and the auto restart
function are available only on the new models.
MICROCODE CHANGE MANAGEMENT
Electronic installation of System/370 microcode is announced for
distributed, networked Micro Channel 370s.  Enhancements are also
announced for System/370 microcode installation on stand-alone Micro
Channel 370s.
       Microcode installation may be required for any of the
following:
o   User-defined configuration changes over an electronic network
    from a user's central site.
o   New microcode release levels that contain new feature support or
    maintenance.
o   Patches -- temporary microcode maintenance
o   RPQ Microcode -- microcode required to support RPQs selected for
    the system.
       In both the networked and the stand-alone environments the new
change management functions of the Micro Channel 370s allow for
nondisruptive installation of their own System/370 microcode.
Microcode may be installed either electronically over an existing
System/370 communication network or manually via diskettes while the
systems continue in operation.  User work on the system is not
interrupted when microcode is being installed.  Activation (Initial
Microcode Load/Initial Program Load) can occur later when convenient.
New microcode can be activated either permanently or on a test basis.
If desired, it is possible to switch back from test microcode to the
original production microcode.
       In a network, the microcode change management functions of the
Micro Channel 370s take advantage of the change management
capabilities contained in the following services of the SNA
architecture:
o   SNA/Distribution Services
o   SNA/File Services
o   SNA/Management Services.
       The Micro Channel 370s are the only IBM processors that take
advantage of the SNA change management capabilities for management of
their own microcode.
       NetView (R) Distribution Manager (NetView DM) provides the
functions for centrally controlling the distribution and installation
of the system's System/370 microcode, in addition to providing
support for distribution and management of software.  NetView DM can
retrieve microcode installed on a Micro Channel 370 test/preparation
system for distribution to networked production Micro Channel 370s.
Either a full complement of microcode can be distributed by NetView
DM from a host or, to reduce network traffic, a version containing
only the changed files can be distributed.
 (R) Registered trademark of International Business Machines
   Corporation.
       New change management functions in the Micro Channel 370s
support the electronic installation of system microcode and
configuration data changes in networked Micro Channel 370s.  Software
support is provided by VSE with VSE/DSNX 2.1 on the Micro Channel
370.  On the central host system, NetView DM support is LU0.  The
stand-alone microcode change management enhancements do not require
DSNX or NetView DM and are independent of the operating system used.
Stand-alone microcode change management is standard on all the new
models.
       VSE/DSNX change management functions can be initiated either
by NetView/DM or by a local customer application written to VSE/DSNX
application interface.  A customer could use either SNA or non-SNA
wide area or LANs to send a request to the local application to
initiate VSE/DSNX to do change management functions.
       Electronic change management of microcode makes it easier to
time and synchronize the installation of microcode.  Electronic
management offers an opportunity to increase the efficiency of
managing distributed systems.  Updates can be staged on remote
systems and then timed to be activated synchronously, maintaining all
the networked systems at the same microcode level.  The need to
coordinate customer and IBM support at the remote sites is avoided.
Data processing skills are kept at one location instead of spread
across locations.  Microcode change management is also useful in
environments, such as the plant floor, where multiple systems in one
location should be maintained at a consistent level.
       Status determination facilities in each Micro Channel 370
maintain a log of all microcode change management commands issued
locally and remotely.  The log file can be retrieved via NetView DM
and examined using the test/preparation Micro Channel 370.  The log
file offers a useful audit of microcode change commands.
       The stand-alone portion of microcode change management is a
standard function on Models 110, 112 and 114.  Support for networked
microcode change management is standard on Models 110, 112 and 114
that ship after March 1991.  It can be added to systems that ship
prior to March 1991, and to Models 010, 012 and 014 with feature
#1002, available after March 1991.
       IBM supplied microcode is copyrighted, therefore users of
microcode change management cannot copy or electronically distribute
microcode unless specific permission is given by IBM, in writing.
For permission to copy or electronically download microcode, users
should refer to the MICRO CHANNEL 370 CENTRAL SITE USER'S GUIDE FOR
CHANGE MANAGEMENT (SA24-4311) or to the statement included with the

Micro Channel 370 diskettes.
       Electronic distribution of microcode for these systems is
limited to the following authorized use:
o   Distribution of patches and maintenance updates provided by IBM
    only
o   Distribution within the customer's enterprise only and not to any
    third party (neither directly nor indirectly)
o   Distribution for use on other 9371s only
o   Electronic copies must be limited to the extent necessary for
    electronic distribution
o   Distribution only to the specified number of machines
o   Unless otherwise specifically authorized, all other terms and
    conditions with respect to IBM microcode remain unchanged and in
    effect.
OPERATIONS MANAGEMENT
In addition to the electronic System/370 microcode change management
functions, new electronic System/370 operations management functions
are available for the Micro Channel 370 with VSE and VSE/DSNX
installed.
       Micro Channel 370s with the new operations management
functions can be accessed by NetView DM using the existing System/370
communications network.  From NetView DM the distributed Micro
Channel 370s can be activated and deactivated (powered on and powered
off).  Commands can be timed to occur at set times or set intervals
(daily and monthly).  When set times are used, automatic time zone
corrections can be made in each system to adjust for locations in
different time zones.  The system clock can be reset as needed from
NetView DM.  For example, Daylight Savings time may require changes
to the system clock.
       The ability to set the Micro Channel 370 to repeat commands at
set times or intervals reduces the network traffic and allows for
efficient, planned operation of the systems without operator
intervention.  Pending operations commands can also be queried and
cancelled from the central site.  These functions are also useful for
environments, such as the manufacturing plant floor, that may require
coordination of multiple systems.
       A log of the executed commands, local and remote, for
operations management and microcode change management can be
retrieved for examination on a test/prep Micro Channel 370.  These
facilities provide useful systems management and audit information.
       The new operations management capabilities in this
announcement are standard on systems that ship after March 1991.
Systems that ship prior to that time may be upgraded with feature
#1002 after March 1991.
TIMED POWER ON
In all the supported System/370 operating system environments, a time
can be set via the operator console or a remote console to
automatically power on the Micro Channel 370.  All the integrated
adapters and integrated devices powered from the Micro Channel 370
will be powered on.  On Model 114 the PS/2 side and any PS/2 devices
powered by the Model 114 are also powered up.  This is standard on
the new models and available on Models 10, 012 and 014 by ordering
specify code #9001.
       In addition to setting the time of power on via a console, the
time of power on may also be set from an application.  Support for
time power on via applications is provided on systems that ship after
March 1991.  Systems that ship prior to March can be upgraded with
feature #1002 after March 1991.
CONSOLELESS OPTION
On the new models the 370 processor console is optional.  It is not
necessary to have a local console if there will be no local system
operator and operation will be remote.  Customers who take advantage
of the remote operation and management functions may not want a local
console.  There are two options.
       One option is to order the System/370 processor console and
simply disconnect it from the system after the initial installation
and set up.  If the console is removed, it must be kept available for
hardware repair/service.
       The second option is to order the consoleless option for the
Models 110 and 112.  No System/370 console is shipped with this
option.  The consoleless option has a small LCD panel for use during
hardware repair.  With the consoleless option installed, the only
customer access to console output locally is through a 3151 attached
to any of the 6024, 6022 or 6026 adapters.  The 3151 can be used as a
console when switched to console mode.  The rest of the time, it has
all the functions and capabilities of other 3151s on the system.  It
will be necessary to use the 3151 at the initial configuration and
setup of the system.  A diskette of the configuration and setup from
an appropriately configured system may also be used for system setup.
       Model 114 customers may take advantage of the Virtual Console
option, which allows use of the PS/2 display as both the System/370
console and a PS/2 display.  All system setup and System/370 console
access can be handled via the PS/2 display without the requirement
for a 3151.  Refer to the Sales Manual for a description of the
Virtual Console.
ALTERNATE IML SOURCE
This function keeps two copies of System/370 microcode and
configuration information on separate DASD.  If the primary DASD
fails during IML, the system will automatically be IMLed from the
alternate DASD.  This feature is most useful when system availability
is critical.  If it is necessary to replace the primary DASD,
Alternate IML Source can also make recovery faster.  The current
production level of microcode and the stored configuration files can
be copied from the alternate DASD to the new primary DASD when it is
installed.
       Alternate IML Source will be shipped on Models 110, 112 and
114 systems after March 1991.  To use Alternate IML Source, if there
are only two DASD on the first system board, the DASD should be
configured to be 265MB and 295MB to provide the reserved space needed
for microcode.  If there are at least three DASD on the first system
board,  the space could also be provided by configuring the first
three to be 295MB.  If the customer plans to take advantage of this
function, when the system is ordered; specify feature codes should be
used to allow preconfiguration of the DASD.  If the codes are not
used when the system is ordered, Alternate IML Source may still be
used but the system microcode must be manually reinstalled first.
Models 010, 012 and 014, as well as new models that install before
Alternate IML Source is available, can acquire Alternate IML Source
with feature #1002.
       Alternate IML Source applies to the System/370 side but not to
the PS/2 side of Models 114 and 014.
AUTO RESTART
Auto Restart is another function that speeds recovery of the system.
After a power failure, auto restart allows the system to
automatically reIML and reIPL when voltage is restored.  The function
is standard on all the new models.  It is selected by turning the
keylock switch to the appropriate setting.  On Model 114, the PS/2
side will also restart and the operating system will load as though
an initial power on had been performed.
COMMUNICATION NETWORK MANAGEMENT ENHANCEMENTS
Link Problem Determination Aid-2 (LPDA-2) support is provided for IBM
intelligent modems in an SNA/SDLC environment.  This allows the Micro
Channel 370 to participate in the IBM Communication Network
Management environment.  LPDA-2 support is provided only for leased
line operation.  This support will be available for IBM CNM modems,
including IBM 785X and the IBM 5822 DSU/CSU.
       SNA Type 2.1 node boundary function allows the Micro Channel
370 to be configured as an SNA Type 2.1 node.  SNA Type 2.1 is the
physical unit type that supports Logical Unit Type 6.2 (LU6.2).
LU6.2 is used for peer-to-peer communication within an SNA network
and is the foundation for Advanced Program-to-Program Communications
(APPC).  APPC allows a great range of connectivity and flexible
network definitions.  In certain configurations, Micro Channel 370
processors can be installed as SNA Type 2.1 nodes with less
programmer time to create and coordinate VTAM (TM) network
definitions than for other SNA types.  Type 2.1 node support is
available for leased and switched SDLC, X.21/SDLC, X.25 and IBM
Token-Ring communications.
       Support for LPDA-2 for half-duplex leased SDLC lines connected
via the Micro Channel 370 SDLC adapters and for SNA Type 2.1 will be
available for VSE with ACF/VTAM (TM) Version 3 for VSE/ESA (TM) in
12/90.  This support is available for VM with either ACF/VTAM
Version 3 Release 3 for VM/SP or ACF/VTAM Version 3 Release 3 for
VM/9370.
       The attachment of V.25bis SDLC modems for dial networks adds
to the connectivity options of the Micro Channel 370.  It enhances
centralized management support for dial networks.  Dial errors are
recorded on NetView screens.  Dial errors may also be processed by a
NetView user exit.  Attachment of V.25bis SDLC modems for dial
networks will be available for VSE with ACF/VTAM Version 3 VSE/ESA.
Supported modems include the IBM 7855, IBM 5853 and the IBM 5858
(EMEA).

320MB AND 265MB DASD CONFIGURABILITY
On Models 110, 112 and the System/370 side of the Model 114, the
first two, standard DASD may be 295MB or the first two DASD may be
265MB and 295MB.  With this option, all the remaining DASD may be
configured to be either 320MB, 295MB or 265MB.  By selecting 320MB,
the user gains 25MB of additional capacity.  The 265MB option is
useful in some Alternate IML Source configurations.  Refer to
Alternate IML Source for the DASD configurations it requires.  VSE
and DPPX/370 support all of the DASD options.  VM/SP and VM/ESA (TM)
support all of the DASD options but only install on DASD configured
as 295MB.
       On the PS/2 side of Model 114, all the attached DASD are
320MB.
       DASD on Models 010, 012 and 014 can also be configured if they
shipped after June 1990, or if specify code 9001 is ordered.
 (TM) Trademark of International Business Machines Corporation.
DASD CAPACITY
The maximum number of integrated DASD supported on Models 112 and 114
is double the number for Models 012 and 014.  Models 112 and 114 can
each support 12 integrated DASD.  A system with 12 DASD provides up
to 3.78GB of storage inside the system.  The increased storage
capacity allows more room for application data growth.  The first two
standard DASD may either 265MB or 295MB.  The remaining DASD may be
configured to 265MB, 295MB or 320MB each.  In Model 112, six may be
attached to each system board.  The optional DASD adapter, feature
number 4050, is needed to add DASD to the second system board.  On
Model 114, six can be attached to the System/370 and via feature
4050, six can be attached to the PS/2.
DUAL SESSIONS FOR 3151 DISPLAYS
This standard function on the new models provides the capability to
maintain two independent emulated 3270 sessions on each attached 3151
ASCII display.  The user can toggle between the two sessions using a
key sequence.  Both 3278 Model 2 and Model 5 emulation are supported.
Dual sessions is provided for 3151s attached via eight port adapters,
the Dual Asynchronous adapter and the standard serial port.
HIGH SPEED PRINTER ADAPTER ENHANCEMENTS
The 3800 Model 3 is added to the list of channel printers supported
by the High Speed Printer Adapter.  The other supported channel
printers are the IBM 3825, 3827, and 3835 page printers and the IBM
6262 Models 014 and 022 Impact Line Printers.  Refer to the
PROGRAMMING REQUIREMENTS section for supported environments.
3270 ADAPTER ENHANCEMENTS
Enhancements to the 3270 Adapter (#6120) include:
o   Host Addressable Printing capability
o   APL2 Character Support
o   Network Asset Management
o   Vital Product Data (VPD) for CUT devices without Feature 6.
       Host-addressable printing allows Micro Channel 370
applications to print directly to printers indirectly attached via
attachment to a CUT terminal, saving ports on the 3270 Adapter.
RS-422-A PRINTER SUPPORT
In addition to supporting terminal printers on the 3270 adapter,
channel printers on the High Speed Printer Adapter, and selected
printers on the RS-232-C ports, selected printers are now supported
in 3287 and 4245 emulation mode on the 512KB eight port adapters with
RS-422-A interfaces (#6024 and #6026 for Models 110, 112 and the
System/370 side of the Model 114).  The IBM 4201 Model 3, 4202
Model 3, 4207 Model 2, 4208 Model 2, 4234 Model 13 and the 4224
Models 301 and 302 are supported.  The RS-422-A connection provides a
very low-cost printer option, however, the operator is responsible
for ensuring that the attached printer is powered on and available.
RS-422-A interfaces do not provide a signal line to give printer
status.  On other interfaces, such as the RS-232-C interface, a
signal line allows the operator to be notified if the printer is not
available.
DYNAMIC PORT RESET AND DYNAMIC DEVICE RECONFIGURATION
Dynamic Port Reset and Dynamic Device Reconfiguration apply to the
Model 110, 112 and System/370 side of the Model 114.  Dynamic port
reset allows individual ports on the eight port adapters, the High
Performance SDLC Adapter, or the X.25/HDLC Packet Network Adapter to
be reset (in the event of a problem with the port) instead of
requiring a system Initial Microcode Load (IML).
       Dynamic Device Reconfiguration allows many characteristics of
individual lines to be changed without requiring a system IML.  It
applies to the eight-port adapters, the Dual Async Adapter, the High
Performance SDLC Adapter, the X.25/HDLC Packet Network Adapter, the
standard serial port and the standard parallel port.
       Dynamic Port Reset and Dynamic Device Reconfiguration improve
system availability to end users by reducing interruption of work
with system IMLs.
       This function is available on Models 010, 012, and 014 that
shipped after June 1990.  It can be added to earlier systems by
ordering specify code 9001.  It is a standard function on Models 110,
112 and 114.
EXTENDED FUNCTION BASE SUPPORT (EBASE) 3270 EMULATION
The 3278 Models 2 and 5 terminal emulation and the 3287 printer
emulation capabilities of the Micro Channel 370 are expanded to
support the full list of EBASE functions that the 3270 data stream
must support for Systems Application Architecture (TM) (SAA (TM)).
Models 110, 112 and 114 support all EBASE functions when emulating
3278 terminals or 3287 printers.  This function is available on
Models 010, 012 and 014 that shipped after June 1990.  It can be
added to earlier systems by ordering specify code 9001.  It is a
standard function on all Models 110, 112 and 114.
 (TM) Trademark of International Business Machines Corporation.

o   Set Timed Power On via Local or Remote Console
o   RS-422-A Printer Support in 3287/4245 Printer Emulation Mode
o   320MB DASD Configuration Option
o   Dynamic Port Reset
o   Dynamic Device Reconfiguration,
o   3270 EBASE Support for 3270 Emulation.
       These functions are on all Models 110, 112 and 114 systems.
Specify code 9001 can be ordered to add these capabilities to
installed Models 10, 12 and 14 systems that shipped before July 1990.
When 9001 is ordered, the HONE configurator should be rerun to verify
the configuration.
ENHANCED FUNCTION (#1002)
This feature includes:
o   Microcode Change Management
o   Remote Operations Management Enhancements
o   Set Timed Power On via Application
o   3270 Adapter Enhancements
o   3151 Dual Sessions
o   3800 Model 3 Printer Support on the High Speed Printer Adapter
    (in addition to the 3825, 3827 and 6262 Models 014 and 022)
       Alternate IML Source will be shipped on Models 110, 112 and
114 systems that ship after March 1991.  Feature number 1002 is
available after March 1991, to add these functions to systems/models
that ship prior to April 1991.  Feature number 1002 is available for
Models 010, 012, 014, 110, 112 and 114.  When #1002 is ordered, the
HONE configurator should be rerun to verify the configuration.
