Table 2-1 shows the codes displayed by the LEDs during normal Domain/OS operation. Refer to Chapter 4 for a description of the LED codes displayed during power-up diagnostics. Table 2-1.
Chapter 3 Theory of Operation This chapter describes the theory of operation for Series 400 systems. Its purpose is to help you understand the operation of these systems to the FRU level so that you can trace problems more effectively. 3.1 System-Level Operation This section presents a general overview of the Domain/OS operating system and the system buses. Refer to Section 3.2 for details about the individual FRUs.
The Model 400t has the following components: • One DIO-II (Desktop computer Input/Output) bus slot for a monochrome or color graphics controller board • One ISA subset bus slot or HP-IB interface slot for a network or HP-IB controller board • Multiple interface ports • Up to two internal disk drives The Model 400dl is identical to the Model 400t with the exception of the CPU board.
Virtual and physical addresses are references to data storage locations, based on the total size of the data storage area. A virtual address is the operating system’s way of referring to a memory location, based on the size of memory from the object’s point of view (virtually unlimited). A physical address is an absolute physical location in the system’s total memory space. The location can be on the system’s memory boards (the main memory) or in a memory component on any other board in the system. 3.1.

3.2 FRU-Level Operation This section describes the operation of the major FRUs in the system. Refer to the appropriate block diagram (Figure 3-1 through Figure 3-5) as you read the descriptions of these FRUs. Refer to Chapter 4 for diagnostic procedures and to Chapter 5 for removal and replacement procedures. 3.2.
– LED – Audio Tone Generator – SCSI Bus* – Centronics Parallel* – RS-232 Serial Input/Output – The system calendar with battery backup • ISA Subset Bus Interface* • HP-IB Bus Interface* • DIO II and SGC* Bus slot for graphics controllers • DIO Bus Interface • DIO II Bus DMA support for SCSI and Centronics Parallel Interface Controllers* CPU The CPU executes MC68030 instructions in response to the operating system and user programs.
Utility Interface (for Domain Compatible Systems) The Domain/OS operating system uses the system clock (in conjunction with the system-ID memories on the network controller board) to provide the proper identification (year, month, day of the month, day of the week, hour, minute, and second) for objectcreation operations such as file creation.. Problems with object creation can indicate a failure in the calendar device, battery, or (less frequently) a failure in reading the memory that contains the system ID.
• Communications with ETHERNET Version 1, Version 2, and IEEE 802.3 compatible controllers • A transceiver that provides connection to “thin” ETHERNET cabling (ThinLAN) through a BNC type T-connector on the back panel • A 15-pin, D-connector on the back panel that provides connection to standard ETHERNET/IEEE 802.
The SCSI interface uses a single-ended (versus differential) connection to daisychained devices. The SCSI controller provides the interface between the SCSI bus and the DIO II bus, and can use 32-bit DMA on the DIO II bus. The length of the SCSI bus cable must not exceed 6 meters (19.6 feet). This maximum cable length includes the length of the bus inside the Series 400 system units and the length of cable inside each external SCSI device. For Model 400t and 400dl systems, the internal SCSI bus length is 0.
RS-232 SIO Interface The RS-232 interface has six modem control lines and an 8-bit DIO interface. It shares the 25-pin D-sub connector with the SIO lines of the Utility Interface chip.
• Provides Multimap DIO-I accesses to system memory and the DIO-II interface for system memory • Performs dynamic bus sizing for the CPU DMA DIO Controller The DMA controller is programmable for byte, word, and 32-bit transfers. This controller supports DMA transfers for the SCSI and Centronics parallel interfaces. 3.2.2 Memory Memory boards for Series 400 systems are available in 2-, 4-, and 16-MB board configurations. The 2- and 4-MB boards consist of 1 Megabit (Mb) DRAMS.
3.23 LED Board The LED board for Model 400s systems houses the LEDs that are visible on the front panel of the system unit. These LEDs indicate the progress of the boot ROM through its initialization, report status codes during normal Domain/OS operation, and display a FRU code in the event of an error. They also indicate power-on and Service mode status.
3.2.5 802.5 Network Controller-AT The 802.5 Network Controller-AT manages the system’s interface to the IEEE standard 802.5 network. The controller has the following features: 3.2.6 • Full compliance with IEEE 802.5 standards. • Texas Instrument TMS380 chip set. • 16 KB of on-board memory. • Ability to operate with a variety of 802.5 Multistation Access Units (MAUs). • 9-pin, D-shell, subminiature female connector to support Type 1 and 2 cables, and an RJ11 phone jack to support Type 3 cables.

Chapter 4 Fault Isolation This chapter provides information about isolating a failing Field Replaceable Unit (FRU). It consists of the following three parts: • Part 1 contains troubleshooting flowcharts and diagnostic information for systems that use Domain Compatible mode. • Part 2 contains troubleshooting flowcharts and diagnostic information for systems that use HP-UX Compatible mode. • Part 3 explains checkout procedures for Series 400 systems, which are referenced by the troubleshooting flowcharts.
offline Test Stimulus Code (TSC). If the TSC or SAX diagnostics fail, replace the indicated FRU. If the system does not report errors, the suspected problem is probably not hardware related. Refer to the following sections for more information about Self Test, TSC, and SAX. Troubleshooting in HP-UX Compatible Mode You must be familiar with the HP-UX operating system to troubleshoot Series 400 system units that are running in HP-UX Compatible mode with HP-UX. You must be able to start and stop processes.
Part 1 Troubleshooting Flowcharts and Diagnostics for Domain Compatible Mode 4.1 Troubleshooting Flowcharts for Systems that Use Domain Compatible Mode This section provides flowcharts that route you through a series of standard troubleshooting procedures for Series 400 systems that use Domain Compatible mode (see Figure 4-1 through Figure 4-9). Refer to Part 3 of this chapter for the checkout procedures that these flowcharts reference.

4.2 Diagnostic Summary for Domain Compatible Mode Several levels of operations exist within systems that run in Domain Compatible mode. Each level has diagnostic or error reporting capabilities. The following sections explain each of these levels.
On a standalone system, you can run the Self Test diagnostics that reside on the Boot ROM; if a disk exists, you can also run Loadable Tests (the part of Self Test that resides in the /SAU directory), TSC, and SAX. If a system is diskless, you can boot Loadable Tests, TSC, and SAX from another disk on the network. If the diskless system is running Domain/OS, you can also run SAX by logging onto a remote system (using the crp command).
Figure 4-10.
4.3 Mnemonic Debugger Level Several diagnostic tools exist at the Mnemonic Debugger (MD) level. In this section, we discuss how to run the Self Test diagnostics and how to interpret the LED error codes. We also explain the MD level LED status codes and briefly discuss TSC diagnostics.
The Test section of Self Test checks all system hardware that loads and executes a standalone program, such as the • CPU • I/O console (keyboard or terminal) • SCSI storage devices • Network controllers Test runs automatically during Normal mode power-up, and from the TE command at the MD prompt. Before Test verifies any SCSI devices on the SCSI bus, it checks the SCSI controller for proper operation.
How to Run the Self Test Diagnostics The following three procedures show you how to force execution of the Self Test diagnostics: • Procedure 4-1 shows how to run Test diagnostics. • Procedure 4-2 shows how to run Extended Test diagnostics. • Procedure 4-3 shows how to run Continuous Test diagnostics. Procedure 4-1. Running the Standard Self Test Diagnostics 1. Log out and stop any user processes. 2. Shut down to the MD prompt by typing the following at the “login:” prompt: login: shut 3.
Procedure 4-3. Running the Continuous Self Test Diagnostics 1. Log out and stop any user processes. 2. Shut down to the MD prompt by typing the following at the “login:” prompt: login: shut 3. At the MD prompt “ > “, type the following: > re < RETURN > 4.
Figure 4-11. Front Panel LEDs Table 4-2 shows the FRU code display and hex numbers for the system as they appear on the front panel display. Use these LED codes to determine the failing FRU. The Self Test diagnostics use the display screen to report the test status. Any failing FRUs are called out on the display screen. When a memory error occurs, Self Test reports the address of the error and the Megabyte of memory in which the error occurred on the display screen.
Table 4-2.
Identifying Defective Memory Boards You must know the memory configuration rules for Series 400 systems before you try to identify a failed memory board. The following list explains these rules (refer to Figure 4-12 as you read the list): • Memory boards must be installed in like pairs. Each board pair forms a block of memory. • Memory board slots on the CPU board are numbered 0A, 0B, 1A, 1B, 2A, 2B, 3A, and 3B.
For example, if the system’s memory configuration consists of two 4-MB boards and two 2-MB boards, and Self Test reports an error at Megabyte 5, the defective board would be the 4-MB board in slot 0B. When you identify a defective memory board, follow the memory board replacement procedure in Chapter 5 to replace it. 4.3.2 MD Level LED Status Codes At the MD level, while in Service mode, the front panel LEDs display system status codes. Table 4-3 lists the codes and their meanings. Table 4-3.
To run the TSC diagnostics, follow Procedure 4-4. Procedure 4-4. Running the TSC Diagnostics 1. Log out and stop any user processes. 2. Shut down to the MD prompt by typing the following at the “login:” prompt: login: shut 3. At the MD prompt “ > “, type the following: > re < RETURN > 4. After the beeper sounds, press < RETURN > and type the following: > ex tsc < RETURN > end of procedure 4.
4.5 Online Level At the online level of operation, several diagnostic tools are available. This section describes the boot shell, the system error log, and the System Acceptance Exerciser (SAX). We document the remainder of the online tools (the /systest/ssr_util directory, Storage Subsystem Tests (SST), Graphics Exerciser (GRTEST), and more extensive information about SAX) in Using Domain Diagnostics, Volume 1. 4.5.1 Boot Shell The boot shell is the first user-space program executed by Domain/OS.
The system responds by displaying the contents of the file, which, if your node has no problems, may look like the following display: tuesday, September 26, 19xx 2:40 pm (EDT) system startup error totals system startups system shutdowns 1 0 The following display shows how the system error log stores a memory failure. Note that “board pair - 2” pertains to the second group of memory board slots on the CPU board, which are labeled 1A and 1B.
Part 2 Troubleshooting Flowcharts and Diagnostics for HP-UX Compatible Mode 4.6 Troubleshooting Flowcharts for Systems that Use HP-UX Compatible Mode This section provides flowcharts that route you through a series of standard troubleshooting procedures for Series 400 systems that use HP-UX Compatible mode (see Figure 4-13 and Figure 4-14). Refer to Part 3 of this chapter for the checkout procedures that these flowcharts reference.

4.7 Hewlett-Packard Boot ROM Functions A Series 400 Boot ROM, Revision 1, is used in the Series 400 system units for the HPUX Compatible Mode. The Boot ROM is on the CPU board. When the system unit is turned on, these Boot ROM instruction sets are executed by the CPU: 4.7.1 • Power-Up Sequence. • Default Configure Mode. Configuring the system unit’s information is in Appendix A. • Test Mode. • Booting the Operating System.
4.7.2 Power-Up Display When you turn your system unit on after the first time and the default functional mode is Hewlett-Packard, the Boot ROM invokes the power-up display and starts its self-test. The Power-Up Display looks like this: Copyright 1990, Hewlett-Packard Company, All Rights Reserved. Series 400 BOOTROM, Rev. 1, 5 Jun 90 MD 12 (date code) Bit-Mapped video MC680n0 Processor . . . System Search Mode RESET to Power-up 4.7.
12. Checksum the Boot ROM. 13. Display CPU type. 14. Look for floating point co-processor. 15. Initialize HP-HIL (keyboard) electronics. 16. Drop Interrupt level. 17. Preload for main RAM test. 18. Test internal HP-IB interface. 19. Test DMA. 20. Test remaining RAM and set up bottom of memory. 21. Report any memory failures and the amount of memory found. 22. Initialize the bottom of memory. 23. Find and report any DIO-II I/O cards in the backplane. 24. Test LAN interface. 25. Test SCSI interface. 26.
The following algorithm is used to determine the output device: 1. If there is a remote card, choose the one with the lowest select code. 2. If there is an internal bit mapped display controller, choose it as console. 3. If there is a bit mapped display controller in DIO-II space, choose the one with the lowest select code. If not go the next step. 4. Use dummy display drivers.
If no output device is present, but a keyboard is, then that keyboard still acts as the console input device. Similarly, if no input device is present, but a display controller is, then that display controller still acts as the console output device. If neither an input device nor an output device is present, the Boot ROM goes ahead and automatically boots the default operating system as long as no errors are discovered during self test (see Section 4.9 for more information about the Boot ROM self tests).
If a failure is detected in the power-up test, the following failure message is displayed: HP98643 (LAN) at 21, 080009000001 Failed This message shows that one of the internal tests on the interface failed. The tests include register operations, shared ram, non-volatile ram checksum and several different internal loopback tests. If extended testing is selected from the Test Menu, the LAN interface is subject to both the normal testing and the external loopback tests.
4.8 Diagnostic Summary for HP-UX Compatible Mode Several levels of operations exist within systems that run in HP-UX compatible mode. Each level has diagnostic or error reporting capabilities: • The Boot ROM level has – – • Series 300 Test Tools have – – – • 4.9 Self Tests Test Mode Computer Tests System Functional Tests CS/80 Disk Tests HP-UX has ce.utilities. Boot ROM Self-Tests When the system unit first powers up, the CPU starts executing Boot ROM code.
Table 4-6 lists these messages. The address’ 5 most significant hexadecimal digits are FFFFF, so only the 3 least significant digits (LSD) are used in the table. When a range of addresses is shown, each address in the range is six addresses apart. When an “UNEXPECTED” failure message equates to an interrupt level, vectored interrupt, or trap, the following situations normally exist: Interrupt levels 1 through 7 Can happen at any time and are usually caused by an interface set to the indicated interrupt level.
Table 4-6. Unexpected Use of (address) Failure Messages 3 Hex LSDs FFA Bus error FF4 Address error FFE Illegal instruction FE8 Zero by zero trap FE2 Check trap FDC TRAPV trap FD6 Privilege violation FCA 1010 Op. Code FC4 1111 Op.

The highest priority failure also sets off the beeper. The lower 7 bits of the LED value are sounded off, most significant bit first, one second per bit, with a zero represented by a low tone and a one represented by a high tone. If the failure was a Boot ROM checksum error, the following message is displayed: CONTINUE AT OWN RISK (Press RETURN To Continue) Once this message has been printed, the RETURN key must be pressed to continue to the boot scanner.
Test LEDs are mounted vertically on the system unit’s front upper right-hand corner. The front panel must be opened to see all of them. Table 4-7.

UNEXPECTED USE OF (address) Possible CPU related error. Refer to Table 4-6. CONFIGURATION EEPROM Failed Configuration EEPROM or associated circuits may not work correctly.
4.9.7 SCSI Testing There are two levels of SCSI testing: normal and extended. Only the normal testing can be completed on system units with internal SCSI mass storage devices. Normal testing is done at power-up or if the Boot ROM is in LOOPING test mode. This test only checks the general functionality of various registers on the interface and it only detects gross failures.
Table 4-12. Extended SCSI Test Messages Message What To Do if internal devices present, type X Cancel the test if there are any internal SCSI devices. The last three sections of this test cannot be run if there are any internal SCSI devices present. Turn OFF ALL SCSI devices Turn off power to ALL SCSI peripherals. If a particular sequence is required for proper system shut-down, that sequence must be followed.
4. Reconfigure the system. The messages shown in Table 4-13 are displayed after the SCSI tests are completed. Table 4-13. Extended SCSI Test System Reconfiguration Messages Messages Meaning and What To Do Remove test connector Connect cable to device Restore power to devices RETURN continues operations This message appears only if the test has been run. Remove the SCSI test connector from the SCSI port on the system unit.
4.10.1 Self Test Control Menu A Self Test Controls menu has three columns to provide you with these controls: • Keys — the keyboard keys used to select the test option you want to run • Test Option — the type of test to run • Selected — indicates the yes/no (Y/N) status of the option The next few subsections explain each Self-Test Controls Menu. Continuous Self-Tests Continuous Self-Tests cause the Boot ROM to continuously repeat the self-tests.
Extended Self-Tests When you select Extended, the self-test starts over and the long memory test will be run. It takes about 4 seconds per megabyte (as opposed to the standard, or default, memory test, which takes about 1 second per megabyte). This mode also invokes extended testing by executing external loopback and cable testing on the LAN and the external SCSI interfaces. Extended SCSI self-tests cannot be performed on internal SCSI mass storage devices.
in any or all of these four addresses. Parity errors are displayed during the Test Memory phase of the self-test and testing continues. Figure 4-16 shows how the memory modules are numbered. Figure 4-16. Memory Module Numbers Refer to Table 4-14 and Table 4-15 to determine the memory module with the failing address. Memory modules are grouped in pairs called Module Pairs representing two memory modules. In Table 4-14 and Table 4-15, blocks of memory are identified by module pairs.

You may continue configuring your system unit by referring to the “Using Configuration Control Mode” section later in this appendix.
Note the line in the menu that reads: Type R RETURN for internal RS-232 console That means to type the command R < Return > To change the internal RS-232 interface to Remote so that you can use the terminal as the system console. Note that sometimes (depending on when you type the command) that some of the display does not appear. C.3 Using Configuration Control Mode Before you use Configuration Control Mode, ensure that your system console interface has been properly configured.
Table C-3. Boot Mode Selection Top/Left Four Amber LED Patterns Undetermined HP-UX Domain Power-Up Display The following Configuration Control Mode screen appears when you first turn a new system unit on. The Configuration Control menu is in the upper right-hand corner. Copyright 1990, Hewlett-Packard Company, All Rights Reserved.

select either the I/O Configuration or Auto System Select Mode. These modes are explained in the following sections. C.4 I/O Configuration Mode These procedures are used for interfaces that are configured under Boot ROM control using keyboard inputs. If your system unit has interfaces with switches or jumpers to configure it, refer to their documentation for instructions. C.4.
The order in which the interfaces appear and their respective number keys may be different than in the above example. Only interfaces that are configurable from Boot ROM control are listed. Interfaces in the system unit that have switches to set their configuration are not listed.
Table C-4. Configuration Mode Entry Error Messages Error Message Meaning and What To Do (No error message) If Configuration Mode does not start and no error message appears, a hardware failure probably occurred. Replace CPU board. EEPROM Has Bad Information Configuration Mode started and main menu may appear, but something failed. Try again. Replace CPU board. EEPROM Load Section Missing Could not load new configuration data. Hardware failure. Replace CPU board.
If the default configurations will be used, you should exit the menu by typing the A command. If you want to change any of the configuration functions, refer to the appropriate configuring the built-in interfaces sections later in this appendix. There are three columns of information: C.4.2 • Keys - the keyboard number keys represent the interface you want to select to configure. Letter keys are for control functions. • Interface - the built-in configurable interfaces.
The three columns in the RS-232 menu are similar to the Configurable Interfaces menu: • Key indicates the feature you want to select. To exit the interface menu, type . • Feature lists each configurable function for the selected interface, • Value shows the current value (or mode) for each function. Note that all Interface menus are not the same. Each has its own features available for configurations. When you select an interface’s function, the prompt line changes.
C.4.3 Using the Control Functions Your Configurable Interfaces menu has three control functions N D A store New values store Default values (then cycle SPU power) Abort without changes • N saves all listed interfaces reconfigured values in the EEPROM. You can turn OFF your system unit, then turn it back ON and the values you configured the interfaces to are used. Then the self-test runs. • D exits the Configuration Mode and resets the factory default configurations.
C.4.4 HP-IB Configuration When your display has the Configurable Interfaces menu and you enter the following command for the HP-IB interface: [key] < Return > this HP-IB menu takes its place: HP-IB Key Feature Value --------------------------1 Sys. Controller Y X to exit menu --------------------------Type [key] RETURN ? The ‘1’ key now changes definition to mean that when it is typed, you want to change the built-in HP-IB interface’s system controller function.
C.4.5 RS-232 Configuration From the Configurable Interfaces menu, type the command key for the RS-232 interface menu and the following RS-232 menu appears: RS-232 Key Feature Value --------------------------1 Select Code 9 2 Interrupt Level 3 3 Remote/Local L 4 Modem Enable Y X to exit menu --------------------------Type [key] RETURN ? Each feature is explained in the following subsections.
RS-232 Interrupt Level Typing the command 2 from the RS-232 menu changes the prompt line to 2 Interrupt Level 3 Type 3, 4, 5 or 6 RETURN ? You can change the interrupt level to one of three other levels. If you want to use level 4, you would type the command 4. The RS-232 menu reappears with the new interrupt level shown. If you do not want to change the interrupt level, type < Return >.
C.4.6 Small Computer Systems Interface Configuration Enter the SCSI menu by typing the command key for the SCSI interface. The Configurable Interfaces menu changes to the SCSI menu: SCSI Key Feature Value -------------------------1 Select Code 14 2 Interrupt Level 3 3 Parity Y 4 Bus Address 7 X to exit menu -------------------------Type [key] RETURN ? SCSI Select Code From the SCSI menu, type the command 1 and the prompt line changes to 1 Select Code 14 used select codes are : 9 12 15 21 Type 0..
Type the command Y if you do want parity checking done by the system unit’s SCSI interface. Type the command N if you do not want parity checking done. After you have made your choice, your SCSI menu changes to show your change. SCSI Bus Address From the SCSI menu, type the command 4 and the prompt line changes to 3 Bus Address Type 0.. 7 RETURN ? 7 Type the command for your new SCSI bus address. After you have made your choice, your SCSI menu changes to show your choice.
LAN Interrupt Level Enter the LAN menu’s interrupt level by typing the command 2. Then the prompt line changes to 2 Interrupt Level 5 Type 3, 4, 5 or 6 RETURN ? Type the command to change the LAN interrupt level, then exit the LAN menu. C.4.8 HP Parallel Interface Configuration Enter the HP Parallel Interface menu from the Interface menu by typing the command key for the HP Parallel Interface.
NOTICE: After you have made the required changes to your system unit’s built-in interface configurations, you must use the Interface menu and make the changes permanent. Otherwise, if you turn the system unit off, then back on again, the original interface configurations will be in effect. The following procedure explains how to configure internal interfaces. Procedure C-1 Configuring Internal Interfaces To configure internal interfaces, perform the following steps: 1.
9. When the Configuration Control menu appears and the system unit is turned on for the first time, you should type the following command to enter the Auto System Select Mode: 2 < Return > 10. If you have already selected an operating system, you should abort the menu without changing it by typing this command: A < Return > C.
The status column has letters indicating yes (Y) or no (N). When you type a number key command, you change the status for that option. Each option is explained in the next three subsections. C.5.1 Scan for System Mass storage devices are searched for operating systems determined by the priority shown below: 1. SCSI interface, select codes 0-31, bus address 7-5, unit 0. 2. HP-IB interface, select codes 0-31, bus address 0, unit 0. 3. SRM interface at select code 21. 4. LAN at select code 21. 5.
C.5.3 Store Selected System To set the Store Selected Sys. option to Y, type the command 3 < Return > The following Auto System Select menu appears: Auto System Select Keys Option Status ---------------------------1 Scan for System N 2 Selected System Y 3 Store Selected Sys. Y E Execute menu A Abort without changes ---------------------------Type [key] RETURN ? You may store either a selected operating system, or the operating system found when the Boot ROM searches for an operating system.
C.5.2 Selected System If you want to boot a specific operating system and more than one exists on your mass storage devices, set the Selected System status to yes (Y), then type the E (execute) command. The system unit resets and the power-up display changes to list mass storage devices with operating systems mounted on them. The display is similar to the following: Copyright 1990, Hewlett-Packard Company, All Rights Reserved. :HP7958, 1405, 0 1H SYSTEM_HPUX Series 400, Rev. 1, 5 Jun 90 md 12 rev 0.
The path to the selected operating system is stored in the EEPROM when you execute the Auto System Select menu. If your workstation or system environment changes and the operating system you previously selected as the default has moved to another mass storage device, you must reconfigure the EEPROM. To reconfigure for the new path to the operating system you want, enter Configuration Control Mode, select Auto System Select and reselect the operating system.
Appendix D Connecting Terminals to Domain/OS Systems You can troubleshoot a Domain Compatible mode system that has display problems by connecting a terminal to the system SIO line. This appendix provides procedures to connect the standard field terminal or another node to the system’s SIO line. D.1 Using a Field Terminal The data terminal currently available for field use is a specially modified IXO model TC301. This device is battery powered with a 1-line, 16-character LCD display.
4. You are now ready to connect the field terminal to the system and access the MD. D.2 Using a Workstation as a Terminal If you need to use another workstation to emulate a terminal, type the following next to the “$” shell prompt: $emt < RETURN > When you receive the “emt > “ prompt, enter the following three command lines: emt > line1 < RETURN > emt > raw emt > tctl -line1 -default < RETURN > The workstation replies with the message emt > EMT remote node ....
