IBM SY27-0345-06 manual Diagnosing Hardware Problems, Power-On Self-Test, Extended Post, Starting

Chapter 3. Diagnostics

The IBM 2210 diagnostic programs test the system hardware and dete problems. The diagnostic routines include three types of tests:

Ÿ Power-on self-test (POST)

ŸExtended POST

ŸMenu-driven diagnostics

The diagnostic package includes service aids that					may	be	used to
nostic	logs	and	to view the vital product	data (VPD).
Note:	When	using a locally attached terminal to run the				IBM	2210	dia
grams, the		service port line speed must		be set	to	9600 bps. This		se
stant	and	cannot	be changed.

Diagnosing Hardware Problems

Running the diagnostics requires complete control of the IBM 2210.

Attention:	Do not shut down	the	IBM 2210	without	the knowledge and	pe
of the	customer. Contact	the	customer’s	system	administrator before	s

Power-On Self-Test

The power-on self-test (POST) provides a basic confidence test of the processor, memory, and interfaces.

Starting

the

POST

The POST runs automatically whenever the

IBM

2210

is

powered

on. If

machine

is

already powered

on and you want to execute the POST:

1Stop

the

IBM

2210

by

unplugging

the

power

cord

from

the

power

2

Plug

the

IBM

2210

into

the

power

outlet.

3

If

the

system OK green)LED

(is

off

and

the system amber LED is

on

a

about 2 minutes, run the Extended POST.

Extended POST

It is possible to run an

extended POST that does not require

attac

minal. Extended POST allows you

to

test

memory

more extensively

than

norm

POST. Follow

these steps

to run

diagnostics

without

a

terminal:

1Stop

the

IBM

2210

by

unplugging

the

power

cord

from

the

power

2

Disconnect

the

cables

from

the

ports.

3

Plug

the

IBM

2210

into

the

power

outlet. Wait for a port gree

(2 to 3 seconds) and

then

push

the

reset

button once. (See
