One Week before equipment delivery:
1.
If
a raised floor is used, cut the cable holes in the
raised floor panels (see "Specifications" pages).
Take necessary safety precautions to prevent per-
sonnel injury because
of
exposed holes prior to
installation of the equipment.
2. Have all afr conditioning equipment installed,
tested, and ready for operation. Balance the air
conditioning system as soon as possible after the
IBM equipment has been installed.
3. Complete painting, plastering, decorating, and
the installation of floor ramps, lighting, and elec-
trical and communication facilities (including any
necessary communications lines, datasets, etc.).
1.2 Building Requirements
In
selecting
a
location for the computer installation,
consider
the
following:
1.
Availability and location of proper and ade-
quate power (including standby power where
required).
2. Space for, and location of, air conditioning
equipment (compressor, air handling equip-
ment, and cooling to'Yer or condenser).
3. Finished
floor-to~ceiling
height of 2.44 meters
(8 feet) minimum (for environmental consider-
ations).
4. Work flow
to
other areas.
5.
Space for storage cabinets, card files, desks,
communications.facilities, etc., as well as for the
daily storage of tapes,.cards, and other supplies.
6. Floor loading capacity.
7.
Proper safety and
fire.
precautions.
8. Electromagnetic interference
..
9.
Excessive atmospheric contamination in the
operating environment, such as from corrosive
gases, dust, and radio-frequency interference.
If
the computer room is located above a manu-
facturing area, ensure
that
holes in the floor
(such
.as
around pipes and telephone lines) are
sealed to prevent flammable, toxic, or corrosive
gases from entering the computer area. The
presence of odors from corrosive gases generally
indicates
an
environment
that
may harm elec-
tronic equipment.
10. Access between the receiving dock
a:t;1,d
the
computer area for movement of the equipment.
1.2.1
Space
and
Layout
Requirements
Space and layout requirements differ for each equip-
ment configuration and depend upon the intended
applications,·as well as
the
physical area available. A
few general rules are:
1•2
IBM 4300 Processors Installation Manual-Physical Planning
1. The floor area required for the equipment
is
de-
termined by the specific components to be in-
stalled, the location of columns, provision for
future expansion, floor loading capacity, etc.
2. As a preliminary check for clearance problems,
paper templates of the units (made to the scale of
your building plans) can be used on the building
plan itself.
It
may be convenient to make a rigid,
full-scale template of the largest unit. Carry this
template along the access route to check for po-
tential clearance problems at doorways, around
passageway corners, and in elevators. ,
Discuss access-route clearance problems with
your IBM representative. IBM equipment
is
usu-
ally shipped.with the covers in place.
If
neces-
sary, shipment without covers may be requested.
Unless otherwise noted
on
individual
"Specifications" pages, all IBM units can be
re.-
duced to at least 750 x 1525 millimeters
(29.5 x 60 inches) for shipment
..
3. Provide space fot
'st<>rage
cabinets, card files,
desks, communications facilities, etc., as
well
as
for the daily storage of tapes, cards, and other
supplies.
4. Store all combustible•materials in properly de-
signed and protected storage areas. (See sections
1.6 "Safety and Fire Precautions" and 1.7
"Storage of
Data
Recording Media.")
5.
At
the option of IBM, test equipment may be
assigned
to
the imtallation to maintain the equip-
ment. The test area should be located
on
the
same floor level as the computing
equipment~

Layout
Before attempting to make a layout, assign priorities
to the
input/
output channels and
to
the control units
to be attached to the channels. (See "Channel Prior-
ity.")
Operational requirements determine the specific
location of the
va~ous
components in the computer
room. Because the separate components are con-
nected by cables
of:
specified length, and because of
space limitations, priority, and the necessity for
l)laintaining clearances between units for servicing,
work space, and aisles, you may need to prepare and
analyze several tentative layouts beforedeciding
upon lhe final plan. ·
If
you plan to in,sian the equipment in two
or
more
stages, a separate.layout should be prepared for each
stage. Consider
c~annel
priority assignments and
cable lengths for each stage.
To make a layout,
an
ac;curate drawing of the pro-
posed area is necessary.
