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.
iv
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.

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.

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.
