PREFACE I

This manual describes the Offline Diagnostics for the Advanced Terminal Processor (ATP). The ATP is an asynchronous device controller for HP 3000/44 and HP 3000/64 computer systems. The ATP interfaces with the Intermodule Bus (1MB) for I/O data transfer. A minimum ATP subsystem consists of one System Interface Board, (SIB), and one Hardwired Port Controller or one Modem Port Controller. It requires 2 I/O slots, uses one 1MB channel address and supports 12 ports. The maximum subsystem consists of one System Interface Board, and eight Port Controllers. It requires nine slots, uses one 1MB channel address and can support 96 terminal ports.

HP 3000/64 computer may have a maximum of 2 ATP subsystems installed, which support 144 terminals. Each ATP subsystem requires one unique 1MB channel address.

This manual is written for the HP Customer Engineer (CE) with the assumption that the reader has a good working knowledge of the lIP 3000 system environment, and is specifically trained on trouble- shooting HP 3000 products. This manual provides information and instructions for setting up the ATP subsystem, and for diagnostic testing. This manual may be used in conjunction with related documentation for the HP 3000 Series 44/64 Computer Systems.

GENERAL INFORMATION I~

INTRODUCTION

This diagnostic test program confirms correct operation of the System Interface Board, Asynchronous Interface Board, Port Connector Assembly and associated cabling. The Port Connector assembly consists of a Mother Board, either modem or direct connect, three or six Mini-Boards, and one cable. It operates on HP 3000 Series Series 44 and Series 64 systems. Communication with the operator is via the system console.

Hereafter, in this document, the following acronyms will be used:

System Interface Board •••••••••••• SIB Asynchronous Interface Board •••••• AIB Advanced Terminal Processor ••••••• ATP

Board replacement is the standard operating procedure and the diagnostics are designed to easily identify malfunctioning boards within the ATP system. The diagnostics allow you to run specific individual tests or all the tests as a group. After all the tests have been run on a particular board, a pass/fail indication will be displayed to indicate which SIB/AlB has passed or failed.

We recommend you run the diagnostics by issuing the "ALL" command rather than specifying particular individual tests •.

REQUIRED HARDWARE

The following hardware is required:

a. A minimal mainframe configuration.

b. A minimal ATP system, ie: one SIB, one Port Controller, which consists of one AlB and one Port Connector Assembly, either Modem or Direct Connect.

c. Loopback Hoods which are included in the product support package (p/n 30144-67801).

One Standard 72 Pin Edge Connector

Twelve 25 Pin Hoods for HP-Modem B Connection Twelve 3 Pin Hoods for HP-DC B Connection Twelve 5 Pin Hoods for HP-DC A Connection

30145-60005

30146-60002

30148-60002

30147-60002

General Information

If necessary, the SIB can be tested without an AlB being present.

Also, the AlB can be tested without Port Connectors being pre- sent. However, the most thorough testing is done with all ATP hardware installed.

General Information

REQUIRED SOFTWARE

The Diagnostic Utility operating System (DUS) tape or diskette, and the ATP Offline Diagnostics are required.

TESTING PHILOSOPHY

The offline diagnostics are designed to test the ATP hardware and a subset of the code resident in the Port Controller Chips (PCC), Modem Controller Chips (MCC), and Modem Scanner Chips (MSC), if applicable. Only a subset of the code can be tested because i t is impossible to emulate all of the actions of terminals and/or modems simply by using loopback mechanisms. The SIB must be functioning correctly in order for the other components of the ATP to be tested. The recommended procedure is to initiate the diagnostics by thoroughly exercising the SIB to ensure that i t is operating correctly. To initiate the SIB tests, respond with the

"ALL" reply when prompted by the diagnostic. If the console goes through the SIB under test, the results must be directed to a line printer. Ensure that the line printer is on-line before you test the SIB. If the diagnostics find that the SIB is properly operating, testing of the AlB commences. It is recommended that the "ALL NO LOOPBACK

tests be run first. If these tests fail, the AlB must be replaced. If they pass, the loopback test should be performed with loopback hoods on the Port Connectors. If these loopback tests fail, loopback tests should be performed with loopback hoods on the AlB. By performing the tests in this sequence and through the use of mUltiple loopback hoods, each port on AlB is tested individually to ensure that the logic associated with it is operating. Thus all the ports on the AlB under test are analyzed.

1-4

General Information

DIAGNOSTIC LIMITATIONS

The diagnostic test limitations of the ATP are the following:

1) When the console is connected to the SIB under test, the messages must be output to a line printer. Make sure that the line printer being used is on line, when the DUS is brought up.

2) In order to be able to initiate the ATP offline diagnostics, the console port must be working. Therefore the console microdiagnostics supplied with the SPU microdiagnostics must be relied upon for diagnosing the console if there are any problems with it.

3) Sometimes i t will be difficult to isolate the problem

area to either the SIB or the AlB unless there are known good

SIBs and/or AIBs with which to test.

OPERATING INSTRUCTIONS I~

INTRODUCTION

The ATP diagnostics are designed to be operated easily. The tests can be run individually if so specified or as a group. We recommend that you do not specify individual tests since by running the tests as a group you will receive the same results in a much faster time.

To operate the diagnostics, the following steps must be executed:

(1) Load the Diagnostic/Utility System (DUS) Tape or Diskette (2) Bring up the Diagnostic/Utility System (DUS)

"Enter Program Name" is displayed.

(3) Respond 'ATPDIAG ' to initiate the Diagnostic.

The ATP Diagnostic Program displays its title message and prompts for the Channel # of the SIB.

Respond accordingly to the questions presented.

MESSAGES AND PROMPTS

Four types of messages are output by the diagnostic:

help, information and error messages.

prompt,

Prompt messages (e.g., which channel number to test, etc.) require you to input the requested information.

Help messages are displayed whenever the HELP command is given, and provide a more complete description of what is needed.

Information messages (e.g., pass/fail) are displayed with no program pause.

Error messages are used to tell you when the ATP responded

unexpectedly to a given stimulus. Error messages are normally

inhibited. These are of the most use when doing actual debugging

and repair of the individual boards.

Operating Instructions

Before the diagnostics are started you can specify whether tHe diagnostics should stop after the first error or whether they should continue to test as much of the system as possible. You can also specify whether success messages or failure messages should be printed- We recommend you respond with a NO to the questions concerning errors and messages, since the results will be summarized at the end of the diagnostic testing-

EXECUTION TIMES I~

INTRODUCTION

The exact execution time for each test or for a group of tests is determined by the following constraints:

• the number

ports under test

• the computer system on which the test is being conducted (Series 44, 64)

• the selection of test sections to be executed

BOARD SIB AlB

EXAMPLE:

TEST ALL

ALL NO LOOPBACK

APPROXIMATE RUN TIME

<2 minutes

The total run time per pass on a fully loaded Series 64 with eight AIBs and 96 ports with no errors is:

The execution times listed above are based on the fastest time:

slower machines, of course, will result in slower pass times.

DESCRIPTION OF TESTS I~

ATP OFFLINE DIAGNOSTIC TESTS

Following is an explanation of the ATP Offline Diagnostic tests. You must specify which SIB to test to the diagnostics.

The diagnostics ask for the channel address of the SIB and the ports which are to be tested. Listed below are all of the sub- tests involved in the diagnostics. The diagnostics run through all of the sub-tests in sequence.

OFFLINE DIAGNOSTIC ORGANIZATION

The SIB is considered to be the foundation of the ATP system. All of its modules must be operational in order to be able to communicate with any ports. Therefore, the SIB modules are tested first. These modules are:

1) Logic for responding to 1MB commands, 2) registers,

3) memory,

4) DMA State Machine, and 5) ATP Bus State Machine.

Each port succession.

2) PCC RAM dump,

3) PCC/MCC Communication, 4) PCC diagnostic loopback,

5) PCC loopback of data signals offboard--requiring loopback hood.

6) MCC/MSC self-test which sends results back to the mainframe, and

SIB MEMORY

SEQUENCING

Description of Tests

This procedure tests the memory on the SIB.

This memory is used to store the 1MB memory offset, pack byte and flags associated with each of the 128 DMA paths. It is tested by writing/reading a checkerboard pattern and writing/reading the address of each location.

The checkerboard test is done with the MDiag bit of the diagnostic control register both on and off. This tests all of the pack byte, as well as the flags.

This procedure tests the sequencing of the ATP bus state machine. It sets up a given set of conditions (e.g. no direct command, bus opcode=idle, board enabled) and then checks the ATP bus as i t single stepped through the logic.

DMA STATE COUNTER

This procedure tests the operation of the board counter on the SIB. It checks that the counter is incremented each time the ATP bus state machine passes through state zero. The counter must be checked by disabling all but one board, and checking when the state ma- chine sees the current-board-enabled signal.

This procedure tests the ATP Bus buffers.

It first uses DMA test code to write data to the ATP bus and reads the looped back data.

It then makes sure that the value of the port pointer looped back matches the value written into the port pointer register.

This procedure tests the data paths which get a direct command to the ATP Bus.

This procedure tests the operation of the FIFO which stores the number of each port wishing to generate an interrupt.

This procedure checks the function of the DMA

state counter. It sets up an opcode which

points to diagnostic DMA code containing all

NOPS. This test simply checks that the coun-

ter increments each time until i t gets to the

halt command, and then resets to zero.

BEGIN FLAG/

LEFT-RIGHT FLAG

This procedure uses test 1 of the diagnostic DMA code to check the operation of the DMA address counter. After an channel initialization, the counter value should be preset to IFFFF. On the next increment i t should overflow and go to zero. It will then count up from zero. Each value of the counter will be stored in memory.

This procedure tests the DMA logic's COMP register and address counter. It loads the DMA registers from memory, and then runs the test which dumps the registers back to memory.

This procedure tests an 1MB read operation using the diagnostic DMA routine which reads a single word from the 1MB and puts i t in the SIB RAM.

This procedure tests an 1MB write operation using the diagnostic DMA routine which writes a single word from the SIB RAM and puts i t in 1MB memory.

This procedure tests the operation of the BeginFlag and LeftRightFlag on the. SIB. The basic tool used in this test is the diag- nostic DMA operation which increments the counter a different number of times for each state of BeginFlag and LeftRightFlag, then stores the count in memory. First each of the four possible states are written to SIB memory register 1 and the test is used to check that the DMA logic sees the correct value of the flags. Then the BeginFlag, LeftRightFlag are both set to 1 and the test is used to check the automatic updating of the flags.

The test names may be abbreviated as indicated. You may enter a list of tests separated by semi-c'olons. ALL indicates that all available AlB tests are to be run. ALL NO LOOPBACK indicates all AlB tests, except those which require a loopback hood, are to be run. NONE indicates that testing of the AlB is not to be done.

Pressing carriage return in response to the prompt will cause the last AlB tests specified (if any) to be retained.

NOTE: ALL NO LOOPBACK is the recommended response when using the diagnostics. If loopback connectors have been installed, ALL is recommended.

Excluding the Modem Scanner Chip self-test and the Modem Scanner Chip dump, which cannot be separated from their MCC counterparts, each test is run individually, and the diagnostics are designed to run the tests sequentially in an order which exercises all the necessary components.

Before you begin the diagnostic tests, the AlB can be tested by initiating the on-board diagnostic as explained below. The offline diagnostic can then begin with the testing of the SIB. After it has been determined that the SIB is

functioning properly, diagnostic tests on the AlB may begin.

a. Flip the tiny toggle momentary switch on the edge of the

AlB PCA to manually reset the AlB so that the self-test

can be initiated,. To initiate the self-test, use a

screwdriver or a similar tool to short out Test Point 5

and Test Point 7, which are between the Junction Panel

Description of Tests

b. Watch the 13 self-test light-emitting-diode (LED) indicators as the self-test program goes through its cycle. Upon completion of the self-test (approximately one second in duration), the LEOs will stop blinking. If no LEOs are lit, the AlB is working properly. If any LEOs are still lit, the AlB is malfunctioning.

The steps above test 90% of the logic on the chips on the AlB board. Once you have confirmed that the AlB chips are functioning, you can begin the AlB diagnostic tests. The diagnostics are able to pinpoint which board is malfunctioning and needs to be replaced. The response for each test is pass or fail. Since board replacement is the standard operating procedure, pass/fail is the only information needed from the diagnostic tests.

A quick way to check if the Modem Scanner Chip is properly functioning on the Modern Mother Board is to attach loopback _hoods on the mini-boards and flip the momentary toggle switch on the rear of the mother board. If the LED remains lit, the mother board is malfunctioning and should be replaced. This test checks the modem logic on the mother board and therefore should not be used when the diagnostics are running.

TEST DESCRIPTION

This procedure verifies the operational SELF TESTS (3) status of thePCC. The maskable inter- rupt path to the PCC/MCC/MSC and the PORT CONTROLLER CHIP data and control paths from the PCC the to the mainframe are tested.

MODEM CONTROLLER CHIP The tests exercise all the PCC's and and return the results to the mainframe.

MODEM SCANNER CHIP The self-tests includes a ROM check-sum, a RAM diagnostic and a timer test.

DUMP TESTS (3) PORT CONTROLLER CHIP MODEM CONTROLLER CHIP HODEl1 SCANNER CHI P

PCC-HCC

COHMUNICATION

This procedure freezes the PCC, issues a dump command and dumps the contents of RAM and Control Registers to mainframe memory. The non-maskable interrupt path to the PCC, the maskable interrupt path and the' freeze code in the PCC are all tested. The test also writes known data from the PCC to the mainframe.

This procedure checks the data path be- tween the PCC and the MCC and the PCC code involved in talking to the MCC, by having the PCC write one byte t,o the MCC and read one byte from the MCC.

4-6

DIAGNOSTIC LOOPBACK

OFF BOARD

LOOPBACK TEST

Description of Tests

This procedure loops back 256 bytes of of data as far as the PCC, but not to the DART or the Port Connector assembly.

The data sent is very specific and the PCC expects the bytes in a specified order. If a byte is received out of order, the PCC interrupts the main- frame, During the test the diagnostics check the data and can now see whether the error occurred on the write path to the PCC or on the read path from the PCC.

This procedure reads data from the mainframe and writes i t back to the mainframe through the use of a loopback hood. The read and write paths from and to the mainframe are tested. The test will send 62 bytes to the PCC and then back to the mainframe and the data is compared. This test requires the use of one or more of the supplied loopback hoods.

NOTE: In order to execute this test, you must place the loopback hood on the mini-boards or the AlB. If the loopback hood is placed on the AlB, you must power OFF the Port Connector Assembly via the power switch on the appropriate AlB. (See figure 4-1) This must be done in order to remove the port connector cable from the AlB and place the loopback hood on. When placing the loopback hoods on the mini-boards, the power may be on or off, however, when running the tests, the power out to the junction panel must, of course, be on.

The loopback test can exercise the AlB

or the Port Connectors. If the hood is

placed on the AlB, the SIB and AlB are

tested. If i t is placed on the Port

Connectors, the SIB, AlB and Port Con-

nectors are tested. If the AlB loopback

fails, the ATB is malfunctioning. If

the loopback passes the AlB test, but

the Port Connectors fail, either the

Port Connector cable is bad or a Port

Connector is bad.

ERROR INTERPRETATION I~

ANALYSIS OF TEST RESULTS

As each sub-test is completed, the diagnostic records a pass/fail indication for that sub-test and any

information related to it. If a failure has occurred but i t is still possible to proceed with other sub-tests, the diagnostics will do so unless you have previously specified stopping after the first error. At the end of the entire test, the diagnostic analyzes the test data and displays the results. The following examples are a representation of the messages that will be displayed after the tests have completed running.

of the SIB.

Error Interpretation

The recommended procedure for running the diagnostics is to respond no to the questions prompting for error messages to be printed. However, if you respond yes, the diagnostics will output error messages in three distinct formats. The responses will not be identical to the examples given, but the formats will be very similar. The information given will supply the user with the name of the board tested, the test exercised and the results of the test. Examples of the formats are listed below:
