The 9370 system includes the 9370 Processors, which are
air-cooled, compatible with System/370, and reside in the
IBM 9309 Rack Enclosure (for clarity, rack will be used in
the rest of this book). There are four versions of the 9370
Processor.
• 9373 Model 20
• 9375 Models 40 and 60
• 9377
Model 90.
These processors use microcode-driven input/output (I/O)
controllers (residing on logic cards) to attach I/O units.
Some of the highlights of the 9370 system include:
• Rack-mounted I/O units
Direct access storage units
Tape units
• An integrated DASD/Tape Controller
• ASystem/370 Block Multiplexer Channel, which
allows you to use System/370 channel-attached devices
• A Work Station Subsystem Controller (uses 3270-type
terminals)
•
Four communication subsystems, which allow you to
communicate over synchronous and asynchronous
lines
• Local Area Network subsystem.

Your Responsibilities
Site preparation for the system is your responsibility.
This book can help you prepare for installing and
expanding your system. Although you are responsible for
this activity, you may need help from IBM, consultants,
contractors, or vendors to complete the tasks.
The primary task of the site planner is to identify the
physical space and system layout requirements for the
equipment. Appendix D, "Physical Planning Templates,"
supplies paper cutouts of the rack to help plan the layout.
[Plastic templates in English (GX24-4046) and metric
(GX24-4047) units are available.]
Site preparation includes:
• Adhering to the planning schedules.
• Preparing the physical location of the units (floor
planning).
o Obtaining, installing, and maintaining coaxial cables
for work stations or the IBM cabling system.
o Inspecting the site to insure that each unit will fit
through doorways and passageways.
• Arranging for installation of any communication
facilities (common carrier, postal telephone and
telegraph, or private) and connecting the system to
these facilities.
• Performing similar planning functions for IBM
input/output (I/O) devices that you plan to attach to
the processor.
Planning the Layout
Operational requirements determine where you place
system components. Some considerations include:
• Flow of work and personnel within the area
• Location of planned safety equipment
• Necessity for maintaining service clearances for all
system units .
1-3

Planning the Layout (Continued)
1-4
• Priority of channel-attached devices
• Space limitations, such as floor-loading capacity,
location of columns, and provisions for growth
• The length of the cables connecting the units in the
system
• Visual access required between a control unit and at
least one of its associated I/O devices
• Work space and aisles.
You may need to prepare and analyze several layouts
before choosing the final layout. If you plan to install the
equipment in two or more stages, prepare a separate
layout for each stage. Consider channel priority
assignments and cable lengths for each stage.
To make a layout, you need an accurate drawing of the
proposed area. For a precise layout, use the paper
templates in Appendix D or order clear plastic templates
(English GA24-4046, metric GA24-4047). The templates
show the required space for weight distribution and
clearances for the operator, service personnel, and test
equipment. Templates also show the radii of swinging
gates and covers, and the location of casters and frame
entry/exit cutouts for cables.
Note: You may overlap clearances shown on the
templates if you maintain the larger clearance. The gate
swing of an auxiliary unit must not interfere with the
gate swing of its corresponding control unit.
Place the equipment so that the lengths of the connecting
cables do not exceed the maximum limits; these limits may
vary. Refer to the device specification pages and cable
schematics for the appropriate limits.
o
o

o
o
Planning Checklist
The planning checklist (Appendix C, "Planning
Checklist") provides a suggested schedule. Your site
preparation may not require all of the suggested steps, or
you may require some additional steps. Be sure you allow
enough time to complete the necessary steps before your
system arrives.
Making the Layout
The prepared layout must be accurate and drawn to scale.
If necessary, IBM uses the layout to determine the
appropriate cable lengths [EMEA (IBM Europe/Middle
East/Africa) has fixed length cables.] Be sure to include
the following items, and any other unique considerations,
on the layout:
• Service clearances required for each unit.
• Location of:
Power receptacles
Air conditioning equipment and controls
File cabinets, desks, and other office equipment
Room emergency power-off controls
All entran"ces, exits, windows, and columns or
pillars.
• The number of:
Control units assigned to each channel
The number of input/output units attached to each
control unit.
Special tasks that you must do for a raised-floor
environment include:
• Showing the location of any obstruction that Inay
affect cable routing.

Making the Layout (Continued)
• Showing the height of the raised-floor above the base
floor.
Note: The raised-floor height should be between 155
millimeters
(6 inches) and 460 millimeters (18
inches).
This height should accommodate piping
and power distribution. The minimum raised-floor
height for the 9370 system, with the System/370
channel feature, is 155 millimeters (6 inches).
However, the
height should also have a minimum of
an additional 115 millimeters (4.5 inches) to ensure
you can run cables and connectors over and under
obstacles.
When a raised-floor
panel is cut for cable entry or
air register, additional panel support may be
required to restore
structural integrity. See
Figure 3-6 on page 3-6 for the recommended floor
cutout
dimensions and placement.
Tasks that you must do for a non-raised-floor
environment include:
• Showing the planned placement of cables for minimum
obstruction.
• Showing the amount of additional cable required, if
the cable route is indirectly between units (such as
along walls or suspended).
• Deciding if you need cable guards or ramps to ensure
personnel and equipment safety.
Always review the final layout to ensure that cable
lengths do not exceed limitations and that all devices
have proper clearances. Notify IBM immediately of any
layout changes that·affect cable lengths.
Storage and Shipping Environment
1-6
IBM designs its units to operate in a controlled
temperature and relative humidity range, and (even when
stored or in shipment) they require some environmental
control. If you store the unit outside the specified limits,
permanent damage can result.
c
o

o
o
Warning: Do not store a unit in a room that has
chemicals that can cause corrosion damage. See
"System Environmental Specifications" on page 2-7,
and individual specifications in Chapter 4.
When removing a unit for shipment or storage, use the
blocks, braces, and preparation procedures found in the
Packaging Bill of Material. This is a protective package
designed uniquely for each unit, and is available from any
IBM Branch Office.
Ship the units through a household goods carrier (padded
van), with appropriate strapping and padding to avoid
transi t damage.

Electrical Power
Primary Computer Power Service
For maximum reliability, the computer power panel
should connect to feeders that do not serve other loads.
Connect electrical noise-producing devices, such as
accounting equipment, card punches, typewriters, and
calculators to panels separate from those feeding the
computer units.
1-7

Electrical Power (Continued)
Branch Circuits
1-8
The branch circuit panel for the computer should be in a
convenient, well-lighted area of the computer room.
Protect the individual branch circuits on the panel with
circuit breakers properly rated according to the
manufacturer's specifications and applicable codes. Label
each circuit breaker to identify the branch circuit it
controls. The power requirements for I/O equipment are
on the unit specification pages in:
• IBM Input/Output Equipment Installation
Manual- Physical Planning for System/360,
System/370,
and 4300 Processors, GC22-7064.
• IBM Input/Output Equipment Reference Installation
Manual- Physical Planning for System/360,
System/370,
and 4300 Processors, GC22-7069.
The grounding wire of the branch circuit must have
insulation and be equal in size to the neutral and phase
conductors.
Terminate branch circuits as close as possible to the unit
they supply-within 3 meters (10 feet). Run branch
circuits in either rigid or nonrigid metallic conduit (or in
compliance with local or national standards). The conduit
system should be continuous, uninterrupted, and
connected to the building or transformer ground; see
Figure I-Ion page 1-9.

Grounding
A machine must be properly grounded. It is recommended
that an insulated green wire ground, the same size as the
phase wire, be installed between the branch circuit panel
and the receptacle. For some small machines such as
terminals, a continuous metallic conduit is adequate for
grounding.
To ensure proper grounding, a licensed electrician should
check the grounding and receptacles for conformance with
the country electrical codes.
For personnel safety, the ground must have sufficiently
low impedance to limit the voltage to ground and to
operate the circuit protective devices if a phase-to-frame
short occurs. For example, the ground path shall not
exceed 1 ohm for 120-volt, 20-ampere branch circuit
devices.
Computer Room Emergency Power-Off Controls
As a safety precaution, provide room emergency power-off
controls for disconnecting the main service wiring that
supplies the computer equipment. Install these controls at
a convenient place for the operator and next to the main
. exit doors of the' room.
Follow national and local electrical codes.
Lightning Protection
1-10
You should install lightning protection devices when:
• An over!J.ead power service supplies the primary power
• The utility company installs lightning protectors on
the primary power source
• The area is subject to electrical storms or
equivalent-type power surges.
o

o
o
Convenience Outlets
You are responsible for selecting and installing lightning
protection devices.
Install a suitable number of convenience outlets in the
computer room and the service representative area for use
by building maintenance personnel and service
representatives. Convenience outlets should be on the
lighting or other building circuits, not on the computer
power panel or feeder. Do not use the service convenience
outlets on IBM units for any purpose Qther than normal
servicing.
