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 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 (CDC)

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 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.

S Stand on a static–free mat.
S Wear a static strap to ensure that any accumulated electrostatic charge dis-

charges from your body to ground.

S Connect all equipment together, including the static–free mat, static straps,

routing nodes, and peripheral units.

S Keep uninstalled printed circuit boards in their protective antistatic bags.
S Once you have removed the printed circuit boards from their protective antis-

tatic bags, handle them by their edges.

v

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.

1–10 Product Information

Connectors for EISA, and Optional Graphics

The system has a slot for an optional EISA (Extended Industry Standard Architec­ture) board or an optional CRX , HCRX , VISUALIZE or CRX–48 graphics board.

EISA

The one–slot EISA I/O port is a superset of ISA (Industry Standard Architecture). It
extends the capabilities of that standard while maintaining compatibility with ISA
expansion boards. EISA provides 32–bit memory addressing and 32–bit data trans­fers. The EISA slot allows quick and easy integration in heterogeneous networks as
well as simple connections of high–speed, low–cost disks and other peripherals.
Some EISA option boards have external connectors for connecting these devices.
Consult the documentation that accompanies each device for specific information
concerning its use.

Optional Graphics

If the system has an optional graphics board installed, it will have one of the follow­ing graphics connectors:

 Color graphics card (CRX–24, CRX–24Z, HCRX–8, HCRX–8Z, HCRX–24,

HCRX–24Z , or VISUALIZE graphics) — This device has a D–sub miniature
connector which is connected to the monitor by a cable, as shown in Figure
Figure 1–4.

 Graphics interface card (CRX–48Z graphics) — This device is connected by a

cable to an external graphics processor, which in turn is connected to a video
monitor, as shown in Figure Figure 1–5.

Figure 1–4 shows the location of the CRX or HCRX graphics connector on the sys­tem unit’s rear panel.

“line” levels.

1–12 Product Information

Monitor Controls, Connectors, and Indicators

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/Off 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. No degauss control exists on the 19–inch grayscale monitor.

Refer to the manual that came with the monitor for detailed information about the
monitor’s controls, connectors, and indicators.

Product Information 1–13

Keyboards

There are three types of Hewlett–Packard keyboards available for use with the
workstation. They are the following:

 ITF Keyboard (Also known as Model # A1099C Keyboard)
 PC Keyboard (Also known as the PC–101 (HIL) Keyboard, the “Enhanced

Vectra” Keyboard, and Model # A2205B Keyboard)

 AT Keyboard (Industry–standard AT–style keyboard that uses

a mini–DIN, PS/2–style, connector, Model # A4030B)

CAUTION: When connecting a HIL device (such as the ITF key-

board) ensure that the device conforms to the
HP–HIL specification. Devices that are not HP–HIL
compatible but have similar connectors may appear
to be compatible, but will damage the system.

Keyboard Differences

Aside from the obvious difference in the appearance of the ITF and PC/AT keyboards
due to the 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 and AT keyboards), an accommodation must be made if the PC/AT
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 1–3
compares the equivalent keys on the ITF and PC/AT keyboards.

NOTICE: Keyboard keys not mentioned in Table 1–3 are the

same on all the keyboards.

Troubleshooting 4

This chapter provides information about isolating a failing Field Replaceable Unit
(FRU).

To troubleshoot HP workstations, you must be familiar with the HP–UX operating
system. You must be able to start and stop processes. You should also be familiar
with the Boot ROM Test Mode, ISL diagnostics, and the SupportWave online tests.

For Series 700 systems, 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. If the tests pass but you still suspect a problem, run the ISL
diagnostics and the SupportWave online tests. Refer to the following sections for
more information about Self Test.

For a complete description on using ISL diagnostics and SupportWave, see the
Precision Architecture RISC HP 9000 Series 700 Diagnostics Manual.

Troubleshooting 4–1

LED Error Codes

This section contains information about the error codes displayed by the LEDs on the
system’s front panel.

If an error occurs during the power–up diagnostics tests, the diagnostics use the front
panel LEDs to display a code for the failing component.

Figure 4–1 shows the location of the system unit’s front panel LEDs. There are nine
LEDs on the front panel. The green LED on the far right indicates that the system is
powered up. The amber LEDs labeled 1 through 8, right to left, indicate system
status and error codes.

Dealing with a Boot Failure

If the workstation’s 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 the workstation, wait a few seconds, then turn the power

back on.

2. Press and hold

Selecting a system to boot.
To stop selection process, press and hold the ESCAPE
key.

Release

Selection process stopped.

Esc

as soon as the following message appears:

Esc

as soon as this message appears:

A short time later, this message appears:

Searching for potential boot devices.
To terminate search, press and hold the ESCAPE key.

The workstation is now searching for devices that may hold file systems from
which it can boot HP–UX. As they are found, they appear in a list, similar to
the following sample list:

Device Selection Device Path Device Type
––––––––––––––––––––––––––––––––––––––––––––––––––––––

P0 scsi.6.0 QUANTUM LPS525S
P1 scsi.5.0 QUANTUM LPS525S
P2 scsi.2.0 TOSHIBA CD–ROM DRIVE

This process may take several minutes. You can terminate the search at any
time by pressing

Esc

.

Troubleshooting 4–13

When the search ends, the following list of actions appears:

b) Boot from specified device
s) Search for bootable devices
a) Enter Boot Administration mode
x) Exit and continue boot sequence
?) Help

Select from menu:

If no disk devices are listed, then the workstation is failing to communicate
with its disks. Recheck the SCSI connections and try again.

If no devices are listed at all, try alternative methods for booting, such as con­necting an external CD–ROM drive.

3. If the search locates a disk, attempt to boot from it by entering the b (boot)

command and a device selection number from the list. For example, if a SCSI
disk is listed as item P0 (as in the example list above), enter the following:

Select from menu: b p0

Return

After a few seconds, the boot messages begin to appear on the screen. You may
hear sounds coming from the disk drive and see a sequence of changing pat­terns on the LED display.

4. If the workstation still fails to boot, there is either something wrong with the

file system or with the hardware.

Boot Administration Environment

The Boot Console User Interface provides an “autoselect” or “interactive” environ­ment after the power–on sequence. The Boot Console User Interface must be in­voked before the Initial Program Loader (IPL) routine. Users do not have to interact
with the interface when the AUTOSELECT mode is enabled.

The Boot Console User Interface executes user–entered commands that perform the
following functions:

 Display the state of Autoselect mode using the AUTO command.
 Set the state of the Autoselect mode using the AUTOSELECT command with

either the ON or OFF option.

 Boot from the primary or alternate boot path or any specified path using the

BOOT command.

 Set or display the real–time clock value using the DATE command (this com-

mand is not supported on Model 715/64, 715/80, , 715/100, and 715/100XC
workstations).

 Return to previous menu using the EXIT command.

4–14 Troubleshooting

 Set or display the Fastsize value (amount of memory initialized during boot)

using the FASTSIZE command.

 Display a menu of commands using the HELP command or a description of

any command as an option to the HELP command.

 Display the model number, version numbers, and jumper settings on the Sys-

tem card using the INFO command.

 Display the current STATION ADDRESS value in stable storage using the

LAN_ADDR command. You must use SS_CONFIG to set this value.

 Select an operating system for the next boot attempt using the OS command.
 Set or display the current values for the console, keyboard, primary, or alter-

nate boot paths using the PATH command.

 Display the most recent HPMC, LPMC, or TOC error information logged into

Stable Storage using the PIM_INFO command.

 Reset the System Unit using the RESET command.
 Search for possible boot devices using the SEARCH command.
 Set or display secure boot mode or the ability to interact with the console de-

vice within the first 10 seconds before boot device selection is disabled using
the SECURE command.

 Display the results of the previous search command using the SHOW com-

mand (this command is not supported on Model 715/64, 715/80, , 715/100, and
715/100XC workstations).

Syntax checking is performed for any supported commands. Error status is displayed
on the console along with any relevant information.

Stable Storage

Stable Storage is non–volatile memory associated with each PA–RISC processor
module. Stable storage is used by the processor (CPU) to store device path informa­tion, the state of the boot flags, HPMC error information, and operating system ini­tialization data.

Troubleshooting 4–15

Boot Command Notations

The BOOT command supports the following three notations:

 Mnemonic
 PA–RISC I/O
 Path number

Type help scsi or help lan for more information on the boot path parameters.
Here are examples of mnemonic notation:

 BOOT

Return

with “no parameters” selects the primary boot path in stable

storage.

 BOOT with the ALTERNATE or ALT parameter selects the alternate boot

path in stable storage.

Here are examples of PA–RISC I/O notation:

 BOOT scsi.<scsi_addr>.<scsi_lun> or

BOOT 2/0/1.<scsi_addr>.<scsi_lun>

 BOOT lan.<server_address>.<init_timeout>.<io_timeout>or

BOOT 2/0/2.<server_address>.<init_timeout>.<io_timeout>

Here is an example of path number notation:

 BOOT P1

Return

attempts to boot from the second path indicated by the

SEARCH command.

Supported Boot Paths

SCSI devices are bootable when connected to the SCSI port on the System card.
Diskless workstations can only boot from the LAN port on the System card.

4–16 Troubleshooting

ISL Environment

The ISL environment provides the means to load the operating system (HP–UX)
environment. The ISL environment also provides an offline platform to execute diag­nostic and utility programs from a boot device when HP–UX does not load.

The ISL program is the first program loaded into main memory from an external
media (LAN, disk, or tape) and launched by the initial program loader (IPL) routine
during the Boot Administration environment.

The ISL environment provides the following capabilities:

 Execute user–entered commands to modify boot device paths and boot options

in stable storage.

 Run off–line diagnostic programs (TDIAG, EISADIAG, and IOMAP).
 Provide automatic booting of the HP–UX O/S after power–on or reset.

The ISL program provides a standalone environment for loading offline diagnostic
and utility programs from the LIF directory. The ISL program also provides user
commands to configure the boot parameters into Stable Storage.

Invoking the ISL Environment from a SCSI Device

Perform the following steps to invoke the ISL environment from a SCSI device:

1. Power–on the System Unit (or cycle the power) to invoke the Boot

Administration mode (environment). The following screen appears:

b) Boot from specified device
s) Search for bootable devices
a) Enter Boot Administration mode
x) Exit and continue boot sequence

ISL User Commands

There are several commands available in the ISL environment that allow a user to
obtain information about the boot characteristics of the system or to modify these
characteristics.

 display – displays the boot and console paths in Stable Storage and the current

setting of the ISL Boot Flags.

 primpath – modifies the primary boot path entry in Stable Storage. The entry

in Stable Storage for the primary boot device begins at byte address 0 and ends
at byte address 31.

 altpath – modifies the alternate boot path entry in Stable Storage. The entry for

the alternate boot device begins at byte address 128 and ends at 159.

 conspath – modifies the console path entry in Stable Storage. The entry in

Stable Storage for the console device begins at byte address 96 and ends at byte
address 127. The entry for the keyboard and mouse devices begins at byte ad­dress 160 and ends at 191.

 listautofl or lsautofl – lists the contents of the (HP–UX) autoboot file.
 support – boots the Support Tape from the boot device.
 readss – displays 4 bytes (one word) from Stable Storage. The readss com-

mand requires a decimal number between 0 and 255 to address four bytes in
Stable Storage.

Dealing With HPMC (Uncorrectable Error)

The power–on sequence follows this path:
POWER-ON > SELFTEST > CONSOLE PATH > BOOT ADMIN MODE > BOOT

PATH > ISL MODE > HP-UX MODE
When the hardware detects an unrecoverable (HPMC) error in the HP-UX environ-

ment, an error message, referred to as an HP-UX Kernel Tombstone is displayed on
the monitor. The state of the system is written to main memory and the entire con­tents of main memory is dumped (written) to the swap area on the system disk.

HPMC error information is logged into Stable Storage; this information is referred to
as PIM (Processor Internal Memory). The HPMC error information is available from
the Boot Administration environment using the PIM_INFO command.

To identify the failed FRU(s) after an HPMC, follow these steps:

1. Examine the first line of the data returned from a PIM_INFO command to dis-

play the latest error information from the last TOC, LPMC, or HPMC interrup­tion detected.

2. Compare the values from PIM_INFO command with those shown in Table 4–6

and take the appropriate action.

Note 2 For the Model 715/75, replace the PCX-T module. For other models,

replace the Motherboard. See HPMC Caused by a Data Cache Parity Error
for more information.

Note 3 While Architected Main Memory space is from 0x00000000 through

0xEFFFFFFF, Model 715 can only use up to 256 MB. With this limitation
any memory address from 0x10000000 through 0xEFFFFFFF is invalid,
and, if given in the System Responder word, the Motherboard should be
(usually) replaced. If the error occurs again, there is a probable Kernel
problem. See HPMC Caused by a Multi-Bit Memory Parity Error 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).

Determining the Faulty SIMM Pair

The address given by the System Responder Address is given as if the memory is
contiguous, even though empty slots are permitted. Memory boards are installed in
pairs of the same memory capacity. The operating system starts mapping memory at
Pair 3, if it exists. In other words, it maps starting with the highest numbered pair
through to the Pair 0. To determine the faulty pair of SIMMs, perform the following
steps.

1. Using Table 4–8, determine the HEX value address range for each SIMM pair

in the system.

mination as possible. To try to locate the faulty (individual) SIMM, reboot the
system. Turn FASTBOOT OFF at the BOOT_ADMIN prompt, set FASTSIZE
to ALL OF MEMORY (0F), and power cycle again.

If the (destructive) memory selftest locates the faulty SIMM, the corresponding
Chassis Code is shown on the LEDs replace the faulty SIMM, otherwise, re­place the SIMM pair identified in this procedure. Return the system state (e.g.,
FASTBOOT) to original condition.
