General Checkout

This general checkout procedure is for computers that are

supported by the QAPlus/PRO Diagnostics test.

Diagnostic error messages appear when a test program

finds a problem with a hardware option. For the test

programs to properly determine if a test

Passed

Failed

, or

Aborted

, the test programs check the error-return code at

test completion. (See “Return Codes” on page 5.)

General error messages appear if a problem or conflict is

found by an application program, the operating system, or

both. For an explanation of these messages, refer to the

information supplied with that software package.

Notes

1. If multiple error codes are displayed, diagnose

the first error code displayed.

2. If the computer reports a POST error, go to the

“Symptom-to-FRU Index” on page 107.

3. If the computer hangs and no error is displayed,

go to “Undetermined Problems” on page 135.

4. If a device cannot be selected from the Module

Test menu, that device might be defective.

001

– Power-off the computer and all external devices.

– Check all cables and power cords.

– Set all display controls to the middle position.

– Insert the QAPlus/PRO Diagnostics diskette into drive A.

– Power-on all external devices.

– Power-on the computer.

– Check for the following responses.

1. One beep.

2. Readable instructions or the Main Menu.

DID YOU RECEIVE THE CORRECT RESPONSES?

Yes No

002

Find the failure symptom in the “Symptom-to-FRU

Index” on page 107.

003

Run the Advanced Diagnostics Test. If necessary, refer to

“Diagnostics” on page 3.

If you receive an error, go to the“Symptom-to-FRU Index”

on page 107 .

Diagnostics

The following tools are available to help identify and

resolve hardware-related problems:

Power-on self-test (POST)

POST Beep Codes

Test programs

Error messages

Diagnostics Diskette

Power-On Self-Test (POST)

Each time you power-on the system, it performs a series of

tests that check the operation of the system and some

options. This series of tests is called the

power-on

self-test

, or

POST

. POST does the following:

Checks some basic system-board operations

Checks the memory operation

Starts the video operation

Verifies that the diskette drives are working

Verifies that the hard disk drive is working

If the POST finishes without detecting any problems, a

single beep sounds and the first screen of the operating

system or application program appears.

If the POST detects a problem, an error message appears

on the screen. A single problem can cause several error

messages to appear. When you correct the cause of the

first error message, the other error messages probably will

not appear on the screen the next time you power-on the

system.

POST Beep Codes

The Power On Self-Test generates a beeping sound to

indicate successful completion of POST or to indicate that

the tests detect an error.

One beep and the appearance of text on the display

indicates successful completion of the POST. More than

one beep indicates that the POST detects an error.

Test Programs

The QAPlus/PRO test programs on the PC Server System

Board Diagnostic Diskette, developed by DiagSoft for

IBM, are the primary method of testing the PC Server. You

can use them to test the IBM components of the system

and some external devices. The amount of time required

to test all components depends on the number of

components. The more optional adapters and devices you

have attached to the system, the longer the testing takes.

Diagnostic programs from the QAPlus/PRO Main Menu

include the following features.

General Checkout/Diagnostics QAPlus/PRO 3

Feature Description

Quick

Check Identifies most problems associated with the

following major components:

System board

Hard disk drives

Diskette drives

CD-ROM drives

RAM

Serial and parallel ports

Video adapter

Printer

Keyboard

Mouse

Module

Test Allows you to:

Run groups of tests in batch

Specify parameters to use for each test

(for example, video modes, disk

cylinders, port addresses, and so on)

Specify the number of passes you want

to run (one to continuous)

Log the test results to a text or dBase

Format (DBF) file

Save all test settings for future use

View System Information

View the server's configuration

information. (For example, you can view

the IRQ/DMA assignments, memory

usage, device drivers, and so on.)

Select System Utilities

Format a diskette

Error Messages

Messages generated by the software—the operating

system or application programs—generally are text

messages, but they also can be numeric. Basically, there

are five types of error messages.

POST error messages

Diagnostic error messages

POST beep codes

Software generated messages.

Multiple messages

Error

Message Description

POST

Error

Messages

Displayed when POST finds problems with

the hardware or detects a change in the

hardware configuration.

POST

Beep

Codes

Sounds emitted from the speaker if POST

finds a problem. One beep indicates POST

completed successfully. Multiple beeps

indicate a problem was found by the POST.

Diagnostic

Error

Messages

Displayed when a test program finds a

problem with a hardware option.

4PC Server HMM

Error

Message Description

Software

Generated

Error

Messages

Displayed if a problem or conflict is found by

an application program, the operating system,

or both. For an explanation of these

messages, refer to the information supplied

with that software package.

Multiple

Messages The first error that occurs can cause

additional errors. Follow the suggested

action of the first error displayed. In this

case, the system displays more than one

error message. Always follow the suggested

action instructions for the

first

error message

displayed.

Return Codes

For the test programs to properly determine if a test

Passed

Failed

, or

Aborted

, the test programs check the

error-return code at test completion. To register the test

properly in the test log, the test programs must generate

one of the following return codes:

Return

Code Description

0 Indicates that the device passed its test.

1 Indicated that the device failed its test.

2 or

greater Indicates that the test stopped or was

aborted.
