SYSTEM VERIFICATION I~
1-1. INTRODUCTION
This section contains verification procedures that are extracts from stand-alone diagnostics to provide
quick, easy to
run diagnostics that verify system operation.
1-2. DIAGNOSTIC AND VERIFICATION PROGRAMS
The HP 3000 Series II Computer System uses three types of test programs. They are ON-LINE
VERIFICATION PROGRAMS, STAND-ALONE DIAGNOSTICS,
and MICRODIAGNOSTICS.
1-3. ON-LINE VERIFICATION PROGRAMS
The on-line verification programs are used to confirm proper operation of peripheral devices (i.e.
printer, terminals, readers, punches etc). These programs run concurrently with other programs under
control of the Multiprogramming Executive Ope'tating System (MPE) and permit uninterrupted
system operation. If the minimum hardware configuration required for MPE is inoperable, on-line
verification programs
cannot be run. The stand-alone diagnostics must then be used. The verification
programs
are described in the Manual of On-Line Verification Programs. The verification programs
and their manual part numbers are listed in table 1-1. Access to the verification programs is obtained
by
entering the following:

NOTE: Refer to paragraph 1-29 for the on-line verification procedure forthe
HP 301 04A PaperTape Reader and
HP 30105A Paper Tape Punch.
The Optical Mark Reader on-line verification program resides
in the PUB group of the SYS account.
1-4. STAND-ALONE DIAGNOSTIC PROGRAMS
The stand-alone diagnostic programs allow Customer Engineers to run maintenance and trouble-
shooting tests on system
hardware and peripheral devices. Each of these programs is independently-
operated
and runs directly on the central processor. MPE is not required and the operating system is

shut-down while stand-alone programs
are running. When aproblem occurs that prevents the use of
both on-line or stand-alone programs, then the microdiagnostics can be used. The stand-alone diag-
nostics
are described in the Manual ofStand-Alone Diagnostics. The stand-alone programs and their
manual part numbers are listed in table 1-2. The CPU diagnostic (D420) is available from the
CPU-Cold Load tape, part number 30000-10016 (11016). (-11016 is a1600 BPI tape.)
The stand-alone diagnostic tapes are created under control of SDUPII (Standalone Diagnostic Utility

The microdiagnostics are microprograms that are built into the system. These are microprograms that
replace the instruction set microprograms in the central processor and ,in some controllers. They
identify problems by checking
the hardware from the most basic level. The operating procedures for
the built in microdiagnostics are contained in Appendix A, and also in the HP 3000 Series II Computer
System Console Operator's Guide, manual part number 30000-90013. The program list is contained in
the Microprogram Listing Manual, part number 30000-90023.

System Verification
1-6. PURPOSE
System verification procedures are used to verify that the system operates correctly. The procedures
may be run after a repair has been made, after a system modification or update has been completed, or
as aconfidence check if some functional area of the system is suspected of a malfunction. Section II of
this manual contains procedures to isolate a fault to a functional area.
A detected malfunction will provide an error message that can be interpreted by referring to the
specific diagnostic contained in the manual of stand-alone diagnostics. The diagnostic manuals also
provide
detailed operating instructions that allow additional testing and analysis to be performed on a
suspected subsystem.
1-7. FACILITIES REQUIRED
Table 1-3 lists the diagnostic tapes required to perform the system verification. Table 1-2 lists the
contents of the Non-CPU Cold Load diagnostic tape. This table lists the contents of a maximum
configured system. Consult the System Configuration Guide shipped with the system to determine the
specific subsystems available at a particular installation. Diagnostics on the tape are in the order
listed in the table. Table 1-1 lists the contents of the on-line diagnostic tape.

-11016 and -11017 are 1600 bpi tapes.
1-8. SYSTEM VERIFICATION PROCEDURES
The system verification procedures contain the instructions required to execute the diagnostic pro-
grams. Each program is loaded using the Cold Load procedure. The verification procedures presented
in this section were preconfigured using SDUP. If a diagnostic is run that has not been preconfigured,
operating instructions and console messages will differ from those presented in this section. In
addition to the verification procedures provided in this section, the on-line diagnostics for the
peripheral equipment should also be exercised for a total system verification. Refer to the appropriate
on-line diagnostic manual for the peripherals in the system.
1-9. SLEUTH 3000
SLEUTH 3000 is a stand-alone utility written in SPL/3000. It is designed to give service personnel
the capability of generating unique I/O test programs that run under the control of SLEUTH 3000.
These programs allow isolation of I/O problems and ease the troubleshooting of these problems.
SLEUTH 3000 has the ability to run up to five different types of I/O device concurrently. It can
also write and execute SIO programs, store and restore programs on magnetic tape, and edit the
programs.
Peripheral devices that do not have on-line and/or stand-alone verification programs require that
SLEUTH 3000 programs be written to test these devices. Several such test programs have been
written for specific I/O peripherals (for example, the SLEUTH07 program described in paragraph
1-32).

PANEL
The system control panel located at the top front of equipment bay 1 provides the system operator and
service personnel the controls and lamps to perform the following functions:
•cold
load and run diagnostics
• load and run user programs
• halt programs
• system dump
•observe the current instruction register
• reset the CPU
• enable or disable the auto restart function after a power failure
All switches located on the front of the control panel are three-position spring-return rocker switches.
These switches have acenter-off position. They are pressed on the top or bottom half to produce the
desired function. When released, they return to the center position.
Located behind the upper right portion of the panel are three switches accessible when the cabinet
door is opened:
CPU RESET-A two-position spring-return switch used to reset the circuits of the CPU.
PANEL DISABLE/ENABLE-A two position switch that enables or disables the system panel for
use.
PF/ARS DISABLE ENABLE-A two position switch to enable or disable the auto restart program
in the event of a power failure.
Table 1-4 lists and explains the function of the switches and lamps that are illustrated in figure 1-1.
1-11. MAINTENANCE PANEL
The HP 30354A Maintenance Panel can be used to perform the functions of System Control Panel. In
addition, the maintenance panel can assist in localizing faults, show the contents of selected registers
and the state of major signals, and modify the contents of selected registers. The function and use of
the panel is described in Section III of this manual.
