Page 71: 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 sys- tems that use Domain Compatible mode. • Part 2 contains troubleshooting flowcharts and diagnostic information for sys- tems that use HP-UX Compatible mode. • Part 3 explains checkout procedures for Series 400 systems, which are refer- enced by the troubleshooting flowcharts. The flowcharts contained in this chapter are logically structured to point you in the right direction (run diagnostics, replace FRUs, and so on).
Page 72 System Support Tape User’s Guide. For Series 400 systems that run HP-UX Compatible mode, you note any error or status messages, and then run the power-up boot ROM diagnostics, known as Self Test. If the Self Test diagnostics fail, replace the FRU that is indicated.

Page 105 HP-HIL interfaces in graphics display controllers are considered an external interface. Note that if an internal HP-HIL interface and a remote terminal are both present in a system, they are both enabled. Similarly, if an external HP-HIL interface and a remote console are both present in a system, they are both enabled, provided no internal key- board is present.
Page 106: Booting Operating Systems Over The Lan
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).
Page 107: Lan Boot Error Messages
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 in- clude register operations, shared ram, non-volatile ram checksum and several different internal loopback tests.

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.

Appendix C Configuring the EEPROM for HP-UX Systems This appendix explains how to use Configuration Control Mode to configure the EE- PROM. Workstation Configurations Your workstation may be configured with one of several combinations of system con- sole, type of operating system, and internal interface settings. If these configurations are matched, the correct displays appear and the requested operating system can be booted. If there is a mismatch, you have to enter Configuration Control Mode and change the EEPROM configuration. Table C-1 lists typical matched configurations.

Either a keyboard with a monitor or a terminal may be used as your workstation’s sys- tem console. When a keyboard is connected to the system unit’s HP-HIL connector, it may always be used for inputting keyboard commands. Depending on the system con- sole used, one of several types of information is displayed at the first power-up.

If the select code is not a 9, the then an accessory DIO-II RS-232 interface has been set to Remote. You must remove the RS-232 accessory card and change its configuration switches to make a permanent change to the accessory card. Refer to the interface card’s documentation. Then, power up the system unit. The system unit resets and the Configure Mode Main menu should appear in the display’s upper right-hand corner. Go on to the “Using Configuration Control Mode” later in this appendix to continue configuring your system unit.

To exit the interface menu, type <X> <RETURN>. • 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.

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. You must cycle system unit power to reconfigure the interfaces to these default values. • A causes the Boot ROM to reset and run the self-test without saving any new interface configurations you may have made. The interfaces’ existing configu- rations are used.

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. 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. The terminal communicates at 300 baud only, and is configured as a DCE device. It plugs into the system, and its attached cable needs no adapters.
