3.2 Cooling (See Figures 3 through 6.)

Cooling

is

accomplished by forced air at ambient room temperature, via a packaged blower located at the bottom

of

the

cabine:t (Figure 3). Distribution

of

air

is

accomplished by an internal plenum which

is

located along the right side

of

the

cabinet opening (as viewed from the front). The air outlet from the blower enters directly into the bottom section

of

the

plenum (Figure 4). The plenum contains seven removable covers located vertically in the appropriate spaces

as

illustrated

by Figure 4.

The blower must be plugged into the

AC

panel at the rear

of

the cabinet, and the main circuit breaker on the

AC

panel

must be in the

ON

position to power up the system.

The blower air switch located on the side

of

the plenum system (Figure 4)

is

wired per Figure

7.

It

is

recommended that the blower remain on for a minimum

of

five

minutes after the Display Panel's LOCK-aN-OFF

switch

is

turned to the OFF position.

The blower

is

shut

off

by the main circuit breaker on the

AC

power panel.

A removable and washable filter

is

located behind the air int

••

!:-=:

g,.~~!:.,.

Two types

of

covers are provided, solid and perforated (see Figures 5 and 6). Solid

.covers

are snapped in place at locations

where there are no card files. Perforated covers are used in locations having an operating card

file.

For

the

Basic Model

8/32

with no expansion, perforated covers are installed at Locations 4 and

5,

and solid covers are

installed in all other locations. If, at a later date, the first memory expansion

is

added, the solid covers at Locations 6 and 7

are replaced with perforated covers.

Two variations

of

blowers are available: 115VAC 50/60

4. POWER SUPPLY INSTALLATION

4.1 Introduction

This section describes the installation

of

the Model

8/32

Power Supply. Mounting information and cabling instructions are

provided for the 34-024 Power Supply in various configurations.

4.2 Mounting

The power supplies mount directly behind the Processor and Expansion chassis (see Figure 8). They are attached

to

the

right mounting upright (viewed from the rear). There

is

adequate slack in the power supply cable

to

allow the power

supply

to

swing out. To prevent the cable from being pinched between the power supply and chassis support rails, a service

loop

is

required.

WARNING

BEFORE SWINGING OUT THE POWER SUPPLIES, THE RACK

LEVELING FEET SHOULD

BE

LOWERED. UP TO FIVE POWER

SUPPLIES CAN

BE

SWUNG

OUT AT ONE TIME AFTER THE

LEVELERS ARE IN CONTACT

WITH

THE FLOOR SURFACE.

The power supplies may be swung in

or

out

on their mounting pivots for easy access

to

the back plane. When they are in

operating position, they are secured by two 10-32 screws which attach

to

the left mounting upright (viewed from the rear).

4.3.2 34-024 System Power Supply. This standard INTERDATA Power Supply

is

used for all power require-

ments in the Model

8/32

System. All three outputs (P5, N15, and

PIS)

are short circuit protected, and regulated

to

±I%

when normally loaded.

PIS

and N15 are oveIVoltage protected.

Refer

to

Switching Regulated Power Supply Manual, Publication Number 29-397 for installation and operating details.

4.3.3 Power Control. The power control circuit diagram for

the

Model

8/32

is

shown in Figure 9. Leads Cl and

C2

are the remote ON/OFF switch leads. All power supplies connected in this manner must be powered from the same

AC

phase. If different phases are used, it

is

not possible

to

turn OFP-the supplies by the Display Panel ON/OFF/LOCK switch.

In this event, additional control lines must be custom wire(j

to

the Display Panel ON/OFF/LOCK switch

as

shown in

Figure 10 and power supply control lines must be grouped according

to

phase. CI and

C2

control one phase,

CIB

and C2B

control a second phase, and

Cl

C and C2C a third phase.

4.3.4 Primary Power Requirements. The 34-024 Power Supply

is

li~itedJo

operating at 115VAC

or

230V

PROCESSOR AND EXPANSION CHASSIS INSTALLATION

5.1

Installation

For

different memory expansions,

it

is

possible

to

have from one

to

three twin chassis in the Mode18/32 System (located

as

shown in Figure 3). Figures

II

through

15

show the three possible configurations.

Prior

to

mounting the chassis, replace the appropriate solid covers on

the

plenums with perforated covers (see Section 3.2).

The 8/.32 Basic System and its memory expansions must always be mounted in a cabinet

that

is

equipped with a blower

and plenum.

It

must be configured

as

shown in Figure

3.

These chassis do

not

have chassis fans. (Seven inch and 14 inch

chassis with fans are

not

to

be used.) When 7 inch I/O chassis without fans are

to

be mounted in this cabinet,

they

must be

installed in positions where duct covers are located (see Figure 3).

CAUTION

IF

A CABINET OTHER THAN

AN

09-069 INTERDATA CABINET

IS USED, THE USER MUST SUPPLY HIS

OWN

FORCED AIR

COOLING SYSTEM.

To

mount

a chassis, slide the chassis into the rack on the chassis support rails from the front

of

the rack (see Figures I and

2). CAUTION

NO

CHASSIS SHOULD BE MOUNTED

IN

CANTILEVER

FASHION. CHASSIS SUPPORT RAILS MUST

BE

USED. IF A

RACK CABINET OTHER THAN AN INTERDATA

IS

USED,

CONSULT THE RACK MANUFACfURER FOR PROPER

SUPPORT RAILS.

The chassis support rails are fastened

to

the mounting uprights

of

the front and rear

of

the rack. The Expansion and

Processor chassis are screwed in place at the mounting uprights in front

of

the rack.

5.2 Basic Processor Configuration and Cabling

Lower Slot 5

is

reserved for the optional Double/Precision Floating-Point Unit (DFU). Lower Slots 0,

1,

and 2 are reserved

for I/O. Either full or halfboard I/O may be plugged

into

these slots. One or two 7 inch halfboards may be inserted

into

the

15

inch chassis via the 16-398 Half Board Adaptor Kit (see Figure 16). The HalfBoard Adaptor Kit may hold two active 7

inch boards

or

one active and one blank 7 inch board, depending on requirements. A 10 inch I/O Controller (provided

it

does

not

use Connector 1) may be inserted via the 02-234 I/O Adaptor Kit (see Figure 17).

No

wiring takes place between

the

boards and

the

adaptors. The adaptors are assigned such

that

the connectors on the boards plug directly

into

the

chassis.

Figure 18

is

a configuration

of

the Basic Processor chassis

as

viewed from the Display Panel side.

It

correlates applicable

cables

to

the associated Processor connectors and Table 1 lists the function

of

each cable.

Figure 19 uepicts the Basic Processor Chassis

as

viewed from the back plane. Shown here are the 35-578 Local Memory

Bus

(LMB) Terminator, the 35-596 Control Address (CA) Terminator, the 17-336 EDMA Cable Assembly, and

the

35-569

MEMORY INSTALLATION AND EXPANSION

7.1

First Memory Expansion (up

to

512KB)/Cabling

Memory may be expanded beyond 128KB, in increments

of

128KB, up

to

5I2KB in one Expansion chassis. Each 128KB

increment requires the addition

of

four 32-198 32KB memory modules.

If

expansion beyond 512KB is desired, a second

Expansion chassis

is

required.

Refer

to

Figure 20.

All

memory modules up

to

a maximum

of

512

KB

are installed in the Expansion chassis above the

Basic Processor chassis. The

MBC

is

installed in upper Slot 1

of

the Processor chassis and the two

LMI

modules are installed

in upper Slots 3 and 6

of

the Processor chassis. Upper Slots

2,4,

5, and 7 remain blank. The first Memory Expansion chas-

sis

accommodates memory

of

256KB, 384KB, and 5l2KB.

7.2 Second Memory Expansion

A second Memory Expansion chassis

is

required for memory size greater than 512KB. Up

to

1MB

of
