USING

THE

IBM 5110 SYSTEM MAPS

MAPs

The

MAPs

guide

you

through

the

service call using step-by-

step

procedures

that

require

you

to

follow

trace

lines

when

responding

to

questions

or

when

leaving

or

entering

a page.

The

MAPs use a logical

approach

for

isolating

the

possible

causes

of

machine

problems

and

point

you

to

that

part

of

the

5110

that

requires

adjustment

or

replacement.

Two

types

of

MAPs are used

in

the

5110

maintenance

library. First,

there

are

the

hard-copy

(printed)

MAPs

within

the

MLM

binder.

These

MAPs are

contained

in

a

separate

removable

binder.

The

second

type

of

MAP

is

the

MOl (MAP

diagnostic

integration).

These MAPs

are

located

on

the

diagnostic

tape/diskette

and

are

shown

on

the

display

screen.

The

system

automatically

pages

through

the

MAPs

when

you

respond

to

the

questions

on

the

display.

__________________________

Begin each call

with

Start

MAP 200. This MAP ensures

that

the

system

is

operating

sufficiently

to

use

other

MAPs

or

MDls.

Start

MAP 200 asks

you

to

record

the

status

bytes,

error

logs,

and

history

logs because this

information

is

lost

on

power

down

or

RESTART.

The

Start

MAP

either

fixes

or

directs

you

to

a MAP

that

tells you

how

to

fix

any

of

the

following problems:

Indi

cator

lights

Bring

up

failures

Process

checks

Display failures

For

other

failures,

the

Start

MAP directs

you

to

the

correct

MAP

through

an

error

code.

If

you

are

certain

the

failure

is

not

covered

in

the

Start

MAP,

you

can go

directly

to

the

other

MAPs

indicated

by

the

®

in

the

chart.

All

MDls have a MAP

as

an

entry.

For

example,

MAP

810-5103

is

an

entry

for

MOl 800

through

805. These

MAPs provide

the

setup

instructions

for

running

the

MDls.

The

MDls are a

combination

of

MAPs

and

diagnostics.

The

MD

Is

call

in

and

run

the

appropriate

diagnostics

and

answer

most

of

the

MAP questions

automatically.

The

procedures

for

diagnosing

intermittent

failures

contain

a

more

detailed

description

of

what

part

of

the

system

each MOl checks.

(.~.\

CI

USING THE MAPS

When

using the MAPs, you must:

READ

CAREFULLY.

The MAPs

can

help you find the

problem only

if

you

follow

instructions

and

answer

questions accurately.

FOLLOW THE SEQUENCE.

Proceed

step-by-step at all

times.

At

times, the MAP instructions might

seem

irrele-

-vant. However, they

can

be

important in determining the

correct error indications.

FOLLOW INSTRUCTIONS. Instructions must

be

carried

out

exactly in the order given. Questions

are

based

on

instructions immediately preceding the questions. Do

not

change

the conditions established by the instructions

before answering the questions. Do

not

press

the

RESTART switch

until

you

are

told

to

do

so

in the MAPs.

When

you

are

asked

to

probe a line in the MAPs, the line

name

and

its active level

are

given. For example:

-Probe H2-G06

(-

machine check).

The -(minus) in

front

of

machine check indicates that this

line

is

active at adown level.
