Emissions Regulations
Federal Communications Commission (FCC)
The Federal Communications Commission of the U.S. government regulates the radio frequency energy emanated by computing devices through published regulations.
These regulations specify the limits of radio frequency emission to protect radio and
television reception. All HP Apollo nodes and peripherals have been tested and comply with these limits. The FCC regulations also require that computing devices used
in the U.S. display the agency’s label and that the related documentation include the
following statement:
NOTICE: This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction
manual, may cause harmful interference to radio
communications. Operation of this equipment in a
residential area is likely to cause harmful interference
in which case the user will be required to correct the
interference at his own expense.
Compliance to these regulations requires the use of shielded cables.
Canadian Department of Communications (DOC)
This digital apparatus does not exceed the Class A limits for radio noise emissions
from digital apparatus as set out in the Radio Interference Requirements of the Canadian Department of Communications.
Compliance to these regulations requires the use of shielded cables.

VCCI Class 1 ITE
Emissions Regulations Compliance
Any third–party I/O device installed in HP Apollo system(s) must be in accordance
with the requirements set forth in the preceding Emissions Regulations statements. In
the event that a third–party noncompliant I/O device is installed, the customer assumes all responsibility and liability arising therefrom.
Compliance to these regulations requires the use of shielded cables.
Electrostatic Discharge (ESD) Precautions
Electrostatic charges can damage the integrated circuits on printed circuit boards. To
prevent such damage from occurring, observe the following precautions when unpacking and installing the board.
D Stand on a static–free mat.
D Wear a static strap to ensure that any accumulated electrostatic charge dis-
charges from your body to ground.
D Connect all equipment together, including the static–free mat, static straps,
routing nodes, and peripheral units.
D Keep uninstalled printed circuit boards in their protective antistatic bags.
D Once you have removed the printed circuit boards from their protective antis-
tatic bags, handle them by their edges.

Laser Safety Statement (For U.S.A. Only)
(For workstations that have a CD–ROM drive installed.)
The CD–ROM mass–storage system is certified as a Class–1 laser product under the
U.S. Department of Health and Human services (DHHS) Radiation Performance
Standard according to the Radiation Control for Health and Safety Act of 1968.
This means that the mass–storage system does not produce hazardous laser radiation.
Because laser light emitted inside the mass–storage system is completely confined
within protective housings and external covers, the laser beam cannot escape from
the machine during any phase of user operation.

Monitor Controls, Connectors, and Indicators
This section describes the controls, connectors, and indicators for the supported monitors.
The Power–On LED, when lit, indicates that the monitor has ac power applied. Use
the following controls to adjust the monitor:
The Power–On button turns the monitor’s power on and off.
The Brightness control adjusts the brightness of the display.
The Contrast control adjusts the light–to–dark and dark–to–light contrast of the
display.
The Degauss control demagnetizes the color monitor. Degaussing disperses any
accumulated magnetic charge from the face of the monitor. Magnetic disturbances such as picture distortion or color impurity can be caused by either
moving the monitor from one place to another or swiveling the monitor on its
base.
Refer to the manual that came with the monitor for information on any other controls
that may be present on the monitor.
The following figures illustrate the monitors for the workstation.

1–12 Product Information
Keyboard
The Model 712 workstation uses a Hewlett–Packard PC keyboard.
You may need to know the differences between the PC Keyboard and the Hewlett–
Packard ITF Keyboard (HP 46201A/B Keyboard). Aside from the obvious difference
in the appearance of these keyboards due to the different arrangement of the keys,
there is also a difference in the keys and their output codes. Some keys on one keyboard (the ITF keyboard for example) may not exist on the other keyboard. These
keys generate codes which also may not exist as output from the other keyboard (or
may be generated by a different key). Codes that are generated when a key is pressed
are called keycodes.
Some applications expect to use keycodes generated by keys existing on one of the
keyboards (the ITF keyboard for example). Since the keys do not exist on the other
keyboard (the PC keyboard for example), an accommodation must be made if the PC
keyboard is to be used. In most cases, it is still possible to use some other key that is
equivalent (generates the same keycode from a different keycap). To do this, it is
necessary to know which keys are equivalent on the two keyboards. Table 1–2
compares the equivalent keys on the ITF and PC keyboards.
NOTICE: Keyboard keys not mentioned in Table 1–2 are the
same on both keyboards.

Memory
The system has two pairs of memory connectors, labeled Slot 0 and Slot 1 for Pair 0,
and Slot 2 and Slot 3 for Pair 1, as shown in Figure 3–13. The model 712/100 has a
third pair of connectors labeled Slot 4 and Slot 5, as shown in Figure 3–14. Install
memory boards according to the following guidelines:
Install memory boards in pairs of the same memory capacity.
Board Pair 0 may have a different memory capacity than Board Pair 1. For
example, if the Pair 0 has 16–MB memory boards, Pair 1 may have 4–MB
memory boards. Always put the largest capacity memory boards in the
lowest numbered slots.
Install the first pair of memory boards in the connectors labeled 0 and 1
(Pair 0) and the second pair, which is optional, in the connectors labeled 2
and 3 (Pair 1). In the 712/100 add the third pair in the connectors labeled 4
and 5 (Pair 2).

Troubleshooting 4
This chapter provides information about isolating a failing component, known as a
Field Replaceable Unit (FRU), in a Model 712 workstation.
To troubleshoot a Model 712 workstation, you must be familiar with the operating
system and be able to start and stop processes. You should also be familiar with the
boot ROM diagnostics, ISL diagnostics, and the SupportWave online tests, which we
describe in this chapter.
To troubleshoot the Model 712 workstation, first check that the power LED on the
front of the system unit comes on. If the LED doesn’t light, follow the instructions in
the flowchart in Figure 4–1. If the LED comes on, follow the instructions in the
flowchart in Figure 4–2 to isolate a failing Field Replaceable Unit (FRU).
NOTICE: The CPU board contains a surface–mount fuse that
fuses +5 volts from the system to the keyboard. This
fuse (1) blows if an overvoltage occurs and (2) protects the system if the keyboard is shorted. Therefore,
if the keyboard fails a diagnostic or won’t function,
replace the keyboard and the CPU board.

Identifying LED–Indicated Conditions
If your monitor remains blank when you power on your workstation, your system
unit’s power LED may flash to indicate an error condition:
A 3/4–second flash indicates the CPU board is defective.
A three quick flash, pause, three quick flash pattern indicates a problem with
the graphics hardware. Check the monitor connections before replacing the
CPU board or the VRAM board.
Dealing with an HPMC (Uncorrectable) Error
When the hardware detects an unrecoverable (HPMC) error in the HP-UX environment, it displays an error message on the monitor. The hardware writes the state of
the system to main memory and dumps the entire contents of main memory to the
swap area on the system disk.
The system logs the HPMC error information, referred to as PIM (Processor Internal
Memory), into Stable Storage. You can display the HPMC error information from the
Boot Administration environment by using the pim command.
To identify the failed FRU(s) after an HPMC, follow these steps:
1. Examine the 12 words listed under Other Processor Data of the data returned
from a pim command. These words represent the following data:
Other Processor Data
IIA Space IIA Offset Check Type CPU State
Reserved Cache Check TLB Check Bus Check
Assists Check Reserved Assist State System Responder Address
2. Compare the words identified in bold with those shown in Table 4–1 and take
the appropriate action.

Note 1 When more than one failed FRU is identified, run the appropriate diagnos-
tics to isolate the failed FRU.
Note 2 While Architected Main Memory space is from 0x00000000 through
0xEFFFFFFF, the Model 712 can only use up to 128 MB (192 MB for the
712/100). With this limitation any memory address from 0x10000000
(0X14000000 for the 712/100) through 0xEFFFFFFF is invalid, and, if given in the System Responder word, the Motherboard should (usually) be replaced. If the error occurs again, there is a probable Kernel problem.
See HPMC Caused by a Multi-Bit Memory Parity Err or for information on
identifying the failed SIMM.
HPMC Caused by a Multi-Bit Memory Parity Error
An HPMC interruption is forced when a multi-bit memory parity error is detected
during a “DMA read” operation of fetching an I/D cache line (32 bytes).
Examine the 12 words listed under Other Processor Data of the data returned from a
pim command during the Boot Administration environment. These words represent
the following data:

Interpreting the Table
The values in the Bus Check and System Responder Address words indicate that a
multi-bit memory parity error was detected by logic in the memory module.
The System Responder contains the SPA of the faulty SIMM pair. To determine the
pair, you need to know the following information:
The SIMM pair sizes and their locations (for example, 16 MB SIMMs in Pair 1
and 8 MB SIMMs in Pair 0)
The total memory size in HEX
4–6 Troubleshooting
Determining the Faulty SIMM
The System Responder Address is stated as if the memory is contiguous. This procedure assumes the following:
memory boards are installed in pairs of the same memory capacity
memory boards are installed first in Pair 0 (Slots 0 and 1)
there are no empty slots between memory boards
To determine the faulty SIMM, perform the following steps.
1. Using Table 4–3, determine the HEX value address range for each SIMM pair
in the system.
Table 4–3. Memory Address Ranges
Memory Size (MB) Address Range
1 MB 0x00000000 – 0x000FFFFF
2 MB 0x00000000 – 0x001FFFFF
4 MB 0x00000000 – 0x003FFFFF
8 MB 0x00000000 – 0x007FFFFF
16 MB 0x00000000 – 0x00FFFFFF
32 MB 0x00000000 – 0x01FFFFFF
64 MB 0x00000000 – 0x03FFFFFF
128 MB 0x00000000 – 0x07FFFFFF
192 MB 0x00000000 – 0x13FFFFFF
For example, if the system configuration is:
Pair 1: 16 MB SIMMs = 32 MB total for pair = 0x01FFFFFF
Pair 0: 8 MB SIMMs = 16 MB total for pair = 0x00FFFFFF
The SIMM address ranges are:
Pair 1: Addresses 0x00000000 – 0x01FFFFFF
Pair 0: Addresses 0x02000000 – 0x02FFFFFF
Troubleshooting 4–7
2. Determine the SIMM pair (starting with Pair 1) that contains the System Re-
sponder Address (as shown using the command) within its range. Evaluate
the SIMM pairs as follows:
NOTICE: Addressing starts at Pair 1, not Pair 0.
A. If the System Responder Address (as shown using the pim COM-
MAND) is between 0x00000000 and 0x01FFFFFF:
Error in Pair 1
B. If the System Responder Address is between 0x02000000 and
0x02FFFFFF:
Error in Pair 0
C. If the System Responder Address is between 0x02100000 and
0x0FFFFFFF:
Address Space Not Filled, (Probable) Motherboard Failure
D. If the System Responder Address is between 0x10000000 and
0xEFFFFFFF:
Invalid Address Space, (Probable) Motherboard Failure
3. Without the actual failed bit number, the failed pair number is as close a deter-
mination as possible. To try to locate the faulty (individual) SIMM, reboot the
system. Turn FASTBOOT OFF at the BOOT_ADMIN prompt and power cycle
again.
If the (destructive) memory selftest locates the faulty SIMM, the corresponding
Chassis Code is shown on the monitor. Replace the faulty SIMM. Otherwise,
replace the SIMM pair identified in this procedure. Return the system state
(e.g., FASTBOOT) to original condition.
4–8 Troubleshooting
HPMC Caused by a Data Cache Parity Error
An HPMC interruption is forced when a data parity error is detected during a Load
instruction to the memory address space or during a data cache flush operation.
Examine the 12 words listed under Other Processor Data of the data returned from a
pim command during the Boot Administration environment. These words represent
the following data:
Other Processor Data
IIA Space IIA Offset Check Type CPU State
Reserved Cache Check TLB Check Bus Check
Assists Check Reserved Assist State System Responder Address
Table 4–4 shows an example of the values for these words:

0x00000000
0x00000000
The value in the CPU State word indicates that register values and addresses stored
in Stable Storage at the time of the HPMC were saved.
The value on the Cache Check word identifies that logic in the processor module
detected a (data) cache parity error.
Replace the Motherboard.
Troubleshooting 4–9
Dealing with a Boot Failure
If the usual boot device (typically a disk) is not responding as it should, you must
attempt to boot from the disk (or another boot device) by selecting it manually.
To boot a device manually, follow these steps:
1. Turn off the power to your workstation for a few seconds.
2. Turn the power back on.

6. If your workstation still fails to boot, there is either something wrong with the
file system or with the hardware. If you suspect a file system failure, see the
manual Using HP–UX for help on dealing with file system failures. If you
think that something is wrong with the hardware, contact your designated service representative.
Troubleshooting 4–11
Running Self Test
This section explains how to identify a failing FRU through the Self Test graphical
display.
When you power on the Model 712 workstation, the system runs a series of diagnostic tests, called Self Test, to check the hardware configuration. These tests check all
FRUs in the system, including any I/O board in the Expansion Slot.
The system displays a screen, similar to the following, while the tests run:
BootRom Version xxx.x
Memory Size: xx MB
Press <ESCAPE> to stop boot sequence.
If an error occurs during the self test, the system displays a second screen depicting
an overview of the system unit components, similar to the following:
4–12 Troubleshooting
The 712/100 screen will depict the additional memory slots.
The defective component is highlighted on the screen. To the right of the diagram,
the self test calls out the defective component. Go to Chapter 5 for instructions about
replacing the failed FRU.
If the self test fails to identify a failed FRU, and you still suspect a problem, run system verification tests, as described in the “Running System Verification Tests” section.
Troubleshooting 4–13
Running System Verification Tests
HP–UX uses a diagnostics product called SupportWave. SupportWave contains the
Support Tools Manager so that you can verify the system operation.
You can access the Support Tools Manager while in a terminal window. If you are
using HP VUE as your interface, you can also access the Support Tools Manager
through the sys_admin directory.
Three interfaces are available with the Support Tools Manager: a command line interface (accessed through the cstm command), a menu–driven interface (accessed
through the mstm command), and the graphical user interface (accessed through the
xstm command).
For more information on SupportWave user interfaces, see the online man pages by
entering the following at a command line prompt:
man cstm

include the following:
lasidiag – tests and verifies the core–I/O functionality within the LASI chip.
The diagnostics test the SCSI interface, LAN interface logic, parallel interface,
audio, RS–232, PS/2 keyboard and mouse interface, real time clock, and the
PC floppy interface and drive.
ldiag – tests and verifies the basic functionality of the PCX–L chip. This tool
tests the CPU, cache, TLB and floating point functions.
memtest – tests and verifies the memory arrays. If an error is detected, the
diagnostic reports the memory card and its slot number that needs replacement.
Memtest also provides a map of the memory configuration so that the user can
identify the type of memory and its slot location.
update – updates the system’s Processor Dependent Code (PDC) firmware on
the FEPROM.
mapper – identifies the configuration of HPPA systems. It displays path, iden-
tification, and revision information of I/O components, configuration of
memory controllers, processors, co–processors, cache, and TLB, as well as
processor board component revisions and values of various HPPA system identifiers, revisions and capabilities.
