General Checkout (QAPlus/PRO)

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
Aborted
, the test programs check the error-return code at
test completion. (See “Return Codes” on page 7.) 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 hangs with a POST error, go to the "Symptom-to-FRU Index" for the system you are servicing.
3. If the computer hangs and no error is displayed, go to “Undetermined Problems” on page 552.
4. If a device cannot be select from the Module Test menu, that device may be defective.

Diagnostics (QAPlus/PRO)

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 turn 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
self-test
, or
POST
. POST does the following:
Checks some basic system-board operationsChecks the memory operationStarts the video operationVerifies that the diskette drives are workingVerifies that the hard disk drive is working
If the POST finishes without detecting any problems, a single beep sounds and the first screen of your operating system or application program appears.
If the POST detects a problem, an error message appears on your 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 turn on the system.
power-on
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, 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 your system, the longer the testing takes.
The test programs on the Diagnostic Diskette include the following features:

Using the Test Programs
The test programs provide advanced functions and utilities for power users and service or support professionals to troubleshoot even the most difficult problems.
Program Navigation: You can maneuver within the
test programs by typing the first letter of a menu choice, using the function keys, or using command-line options.
Using the First Letter of a Menu Choice
Throughout the test programs, pressing the first letter of an option on a menu is the same as moving to that item with the cursor and pressing Enter; however, this function is not enabled on Test Group Screens.
Using the Function Keys
Use the following keys to maneuver throughout the test programs:
Keys Action
Enter Select an item, run the test module, or run

test programs to use the BIOS for screen writes.
XXX=test group (for example, MBD/MEM/VID/HDU/FDU/KBD/COM/LPT, and so on), omits the designated test group from testing.
The /USERCONFIG=file command line option tells the test programs to look for a user diagnostic configuration file other than the default USERDIAG.CFG.
The /SCRIPT=file[,R] command line option with the “,R” runs the selected script. Please see “Scripting” on page 10 for a description of scripting.
Note: You can use a “–” instead of a “/” as
the command line switch.
Viewing the Test Groups: As you move the
cursor bar up or down in the Test Module Selection window, the right hand screen changes to show the attributes, parameters, and the selected tests of the corresponding Test Group. The diamond “” mark indicates a module selected for testing.
The indicated attributes are characteristics of the selected test module that are used by the test programs to determine which tests to run or how to run selected tests. Attributes are also used to limit the allowable range of parameters (for example, – ending cylinder).
Parameters are values you select to establish the scope of tests. For example, you can select Extended Memory testing parameters and limit the testing to a specific range of test blocks by specifying the starting and ending memory block. This might be appropriate if prior experience indicates that problems are likely to exist in a

Diagnostics and Test Information

The following list contains problems and references for diagnosing a PC Server 300 Type 8640.
Notes
The QAPlus/PRO diagnostic program recognizes
the primary processor as LUN 1 and the secondary processor as LUN 2. During testing the program automatically tests LUN 1. You must select LUN 2 if you want the program to test the secondary processor.
The type of DASD diagnostics required to test
the hard disk controller (adapter) and drives is determined by the type of hard disk adapter installed in the computer.
Always start with “General Checkout
(QAPlus/PRO)” on page 4.

Power Supply Voltages
Note: Verify that the voltage-select switch (if applicable)
is set for the correct voltage.
If the power-on indicator is not on, and if the power-supply fan is not running, check the power cord for proper installation and continuity.
If the power cord is OK, either the power supply is defective or a defective device is causing the power supply to shut off. Check the power supply voltages.
If the voltages are incorrect, replace the power supply. If the voltages are correct, and the Symptom-to-FRU index does not solve the problem, go to “Undetermined Problems” on page 552.

Setup (BIOS Utility)
You can start the Setup Utility program during the POST or in any DOS Full Screen. However, the procedure for starting the Setup Utility program during the POST depends on the machine type of the computer you are servicing.
Notes:
1. If a configuration error occurs during POST, press F1 to bypass the error. (A configuration error message appears before the operating system loads.)
2. Do not start the Setup Utility while using the EISA Configuration diskette.
3. The EISA Configuration diskette must be used to configure computers that have a EISA configuration. For information on how to use the EISA Configuration diskette, refer to the documentation shipped with the system.
4. The procedure for starting the Set Utility will not work in an OS/2 DOS Window.
Starting Setup During the POST: To start the
program during the POST do the following.
1. Power-On the computer.
2. During the POST memory test, press and then release the Spacebar; then press and release the
CTR+ALT+S keys simultaneously.
System Utilities
The Diagnostic Diskette contains utilities for formatting diskettes, performing a low-level format on a hard disk, and editing.
Formatting Diskettes: To format a diskette within
the Diagnostic programs, select one of the following options:
PC Server 300 - Type 8640 21
Page 26
Format A: high density — 1.44MB Format A: low density — 720KB Format B: high density — 1.44MB Format B: low density — 720KB
After selecting one of the above options to format a diskette, follow the instructions that appear on the screen.
Using the Low-Level Format Program:
Depending on the hard disk capacity, the Low-Level Format program could take up to two hours.
When To Use the Low-Level Format Program
Use the Low-Level Format program:
When you are installing software that requires a
low-level format
When you get recurring messages from the test
programs directing you to run the Low-Level Format program on the hard disk
As a last resort before replacing a failing hard disk
drive
Hard Disk Drive Preparation: When the
Low-Level Format program is finished, restore to the hard disk all the files that you previously backed up.
1. Partition the remainder of the hard disk for your operating system. (The commands vary with the operating system. Refer to your operating-system manual for instructions.)
2. Format the hard disk using your operating system. (The commands vary with the operating system. Refer to your operating-system manual for instructions.)
3. Install the operating system.
You are now ready to restore the files.
File Editor: The File Editor is an ASCII text editor that
uses simple function key commands. To access the File Editor:
1. Select File Editor from the Enter.
2. Insert a diskette into Drive A or Drive B before selecting the file you want to edit, then select the file you want to edit from the Files selection box.
3. Make your changes. The arrow keys move the cursor, and the function keys perform search and block editing functions. (See “File Edit Function Key Usage” on page 23.)

At the start of the diagnostic tests, the Module Test Menu is displayed. Normally, all adapters and devices installed in the computer are highlighted on the menu.
If an adapter or device that is not installed in the
computer is highlighted on the menu, use the procedure in “Undetermined Problem” on page 83 to find the problem.
If an adapter or device is installed in the computer
and is not highlighted on the menu, you have one of the following conditions:
– The diagnostic code for the adapter or device is
not on the diagnostic diskette. Run the diagnostics provided with that device.
– The SCSI controller failed (on the system board
or SCSI adapter). – An unrecognizable adapter is installed. – The missing device is defective or it requires an
additional diskette or service manual. – A defective adapter caused the device not to be
highlighted on the menu.
If a device is missing from the list, replace it. If this does not correct the problem, use the procedure in “Undetermined Problem” on page 83.

System Board Replacement
Notes
1. The BIOS and Vital Product Data (VPD) for the computer you are servicing must be installed on the new system board (FRU) after it is installed in the computer. To do this, you must run the
Flash Update program using the Flash Update diskette shipped with the new system board FRU. See “BIOS Levels” on page 68 “Vital
Product Data” on page 89, and “Flash (BIOS/VPD) Update Procedure” on page 69.
2. Always ensure the latest level of BIOS is installed on the computer. A down level BIOS may cause false errors and unnecessary replacement of the system board.
3. The processor is a separate FRU from the system board and is not included with the system board FRU. If you are instructed to replace the system board, do the following.
4. Install the processor from the old system board on the new system board.
5. If any of the following options are on the old system board, install them on the new system board.
External cache memory and cache tag RAM
Memory modules
Extended video memory
6. Ensure that the new system board jumper settings match the old system board jumper settings.
7. If the new system board does not correct the problem, reinstall the options on the old system board, reinstall the old system board, then replace the processor.
Test Programs
The Diagnostics test programs, developed by DiagSoft for IBM, are the primary method of testing the computer. 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 your system, the longer the testing takes.
The test programs on the Diagnostic Diskette include the following features:

Viewing the Test Groups: As you move the
cursor bar up or down in the Test Module Selection window, the right hand screen changes to show the attributes, parameters, and the selected tests of the corresponding Test Group. The mark indicates a module selected for testing.
The indicated attributes are characteristics of the selected test module that are used by the test programs to determine which tests to run or how to run selected tests. Attributes are also used to limit the allowable range of parameters (for example, – ending cylinder).
Parameters are values you select to establish the scope of tests. For example, you can select Extended Memory testing parameters and limit the testing to a specific range of test blocks by specifying the starting and ending memory block. This might be appropriate if prior experience indicates that problems are likely to exist in a specific area of memory. By selecting these limiting parameters, you reduce memory testing time.
Scripting: Scripting allows you to select specific
groups of tests, testing parameters, and options. Your selection is saved for later use as a test a test script, first select all the appropriate test groups and specific tests you want to run from the Module Testing section under Diagnostics. You should also select appropriate testing parameters and options. See “Program Navigation” on page 84, for instructions to save a test script.

. To set up
Changing Logical Unit Numbers: In some
instances, you can have more than one logical unit number (LUN) for a particular module. LUNs represent individual devices within a test group or module. For example, you might have two diskette drives or two hard disk drives; or, you might have base, extended, shadow, and cache memory installed in the computer. This configuration might result in as many as four or five different LUNs in the Memory Test Group. Or you might have base, extended, shadow, and cache memory installed in the system which might result in as many as four or five different LUNs in the Memory Test Group.
From either the Module Test Menu or the Test Group window, you can change to a different LUN (where applicable) by pressing the plus (+) key (next LUN), or the minus () key (previous LUN).
Test Group Specifications: In the
upper-right-hand portion of the testing screen (or just the upper portion if you switched to an individual test group screen) are the specifications for the related test group.

Locations

The following location information is for the PC Server 310 Type 8639.
“Expansion Slots/Riser Cards.”“Keylock Assembly Exploded View” on page 91.“System Board” on page 92.
Expansion Slots/Riser Cards
All Type 8639 computers have seven expansion slots, two of which are PCI expansion slots. The other five expansion slots are either Micro Channel or ISA, depending on model.
The PCI slots and their adjacent Micro Channel or ISA expansion slots are
shared expansion slots
that an adapter can be installed in either the PCI expansion slot or the adjacent Micro Channel or ISA expansion slot, but not in both.
A SCSI-2 Fast/Wide PCI Adapter is installed in one of the PCI expansion slots. An Ethernet adapter is installed in one of the Micro Channel or ISA slots.
This leaves one PCI slot and three Micro Channel or ISA slots available for future expansion. For example, you can add adapters to provide communications, specialized graphics, and sound.
. This means

Symptom-to-FRU Index Supplement

The Symptom-to-FRU Index lists error symptoms and possible causes. The most likely cause is listed first. Always begin with “General Checkout (Models 0XT, 0Z0, 0ZT, 0D0, 0DT)” on page 57. This index can also be used to help you decide which FRUs to have available when servicing a computer. If you are unable to correct the problem using this index, go to “Undetermined Problem” on page 83.
Notes
If you have both an error message and an
incorrect audio response, diagnose the error message first.
If you cannot run the diagnostic tests, but did
receive a POST error message, diagnose the POST error message.
If you did not receive any error message, look for
a description of your error symptoms in the first part of this index.
Check all power supply voltages before you
replace the system board. (See “Power Supply” on page 71.)
Important
1. Some errors are indicated with a series of beep codes. (See “Beep Symptoms” on page 96.)
2. The processor is a separate FRU from the system board; the processor is not included with the system board FRU. (See “System Board Replacement” on page 81.)
