Data Processing

System

This manual

contains

information

necessary

to

operate

the

System/370

Model

145

Processing

Unit

and

integrated

devices,

except

the

IFA. Order

numbers

for

manuals

containing

operating

procedures

for

individual

input/

output

devices can be

found

in

the

IBM

System/360

and

System/370

Bibliography,

GA22-6822.

Controls

and

indicators used

only

by

service personnel are covered

in

maintenance

documentation

for

the

system.

System/370

Model

145

performs

data

manipulations

and

input/output

operations

by

executing

microprogram

routines.

The

routines

executed

are

determined

by

the

machine

language

instruction

being processed.

The

Initial

Microprogram Load (IMPL) disk

contains

the

370

micro-

program

and

is

inserted

into

the

Console File (CF)

before

power

is

applied

to

the

system.

When

power

is

applied

to

the

system

and

the

370

micro-

program

is

loaded

into

control

storage,

the

system

is

ready

to

load

the

operating

system (OS, DOS, etc.)

or

a stand-

alone

program.

These_programs are loaded

by

using

the

INTRODUCTION

Initial Program Load (IPL)

procedure

in

this

manual.

Operating

procedures

necessary

before

a

problem

program can be run are:

1. Disk Cartridge Insertion (lMPL disk)

2. Power-on

3.

IMPL

(automatic

with

power-on)

4. IPL

the

operating

system (if required).

Whenever

power

has been removed

from

the

system,

these

four

procedures

must

be followed. When

power

is

dropped,

the

contents

of

control

storage

and

main

storage are invalid.

then

re-IPL.

POWER

and

THERMAL

CHECK RECOVERY

When a

power

supply failure

or

overtemperature

condition

occurs during a system

operation,

a power-off sequence oc-

curs.

The

POWER check indicator

on

alone indicates a

8

power

supply failure.

The

THERM indicator on along

with

the

POWER check indicator indicates an overtem-

perature

condition.

1. Press CHECK RESET key (resets

the

indication and

allows

the

POWER

ON

key

to

be operative).

2. Press POWE R

ON

key.

If

the

condition

causing

the

failure was

temporary,

power

will

come

up

normally. If

power

cannot

be restored, see

"Handling

Abnormal Situations--Introductory

Flowchart,"

page

Address Compare

Control

This switch is used with

the

ADDRESS COMPARE

and

the

STORAGE SELECT

rotary

switches

to

determine

the

action

taken by

the

CPU-as a result

of

an address

compare

match.

The

CPU

should

be

in

manual

state

(MAN

indicator

on) before using

this

switch. (Example: Press STOP key.)

SYNC/NORM

This position

is

the

normal

operating

position. This

position also provides a

sync

pulse

for

service use,

and

does

not

result

in

a

an address

match.

STOP

This position provides a soft-stop whenever an address

match

is

detected.

To

restart

the

CPU, press

the

START

key. With

the

switch in

this

position,

the

TEST

indicator

is

on.

HARD STOP

This position

is

for

service personnel and is described

in

maintenance

documentation.

With

the

switch

in

this

position,

the

TEST

indicator

is on.

STORAGE SELECT SWITCH

• This switch selects

the

proper

storage

for

manual

store/

display operations.

It

is

also used with ADDRESS

COMPARE and ADDRESS COMPARE CONTROL

switches for address match functions.

•

Store

and display functions should be initiated from

the

PR-KB because

that

facility

cannot

cause con-

current

I/O operations

to

overrun.

The

manual store

and display functions should be used only when no

I/O operation

is

in

process

or

when loss of I/O infor-

mation

is

unimportant.

switch

in

this position, a diagnostic logout into

main storage (locations

128

through 704)

stops

processing

and

turns

on

the

The

diagnostic logout can

contain

information

about

a machine

check, channel

check,

or

an interface control check.

After

a diagnostic logout, you

may

run

the

System Error

Note: Programs using storage locations

128

through

704

are

invalid

after
