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 pubhshed regula-
tions. 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 com-
putin~ devices used in the U.S. display the agency’s label and that the related docu-
ment~tion include the following statement:
WARNING: This equipment has been tested and found to comply with the
limits for aClass Adigital 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 acommercial environment. This equipment
generates, uses, and can radiate radio frequency enerb~and, if
not installed and used in accordance with the instruction
manual, may cause harmful interference to radio
communications. Operation of this equipment in aresidential
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 Alimits for radio noise emissions
from d;gital 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.
Emissions Regulations Compliance
Any third–party 1/0 device installed in HP Apollo system(s) must be in accor-
dance with the requirements set forth in the preceding Emissions Regulations
statements. In the event that athird–party noncompliant 1/0 device is installed,
the customer assumes all responsibility and liability arisingtherefrom.
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 ckxming, &bservethe following precautions when
unpacking and installing the board.
●Stand on astatic–free mat.
●Wear astaticstrap to ensure that any accumulated electrostatic charge dis-
charges from your body to ground.
●Connect all equipment together, including the static–free mat, staticstraps,
routing nodes, and peripheral units.
.Keep uninstalled printed circuit boards in their protective antistaticbags.
●Once you have removed the printed circuit boards from their protective an-
tistatic bags, handle them by their edges.

Product Description
The Model 735 is ahigh–performance, PA–RISC–based workstation that is de-
si~g+edto run the HP– UX operating system.
The Model 735 workstation houses up to two internal mass storage devices con-
nected to one of two internal SCSI interfaces: single-ended orfasthvide. With the
single–ended interface, the workstations have their firsthard disk drive bay fitted
witheither a 525–MB or 1– GB hard disk drive. The second disk bay maybe
fitted with either a3.5–inch floppy drive or a 525 –MB or 1–GB hard disk drive.
With the fast/wide interface, the workstations have their hard disk drive bays fitted
witheither one or two 1– GB hard disk drives. Hard disk drives are pre–for-
matted. (The 1– GB drives are not interchangeable between single–ended and
fast/wide interfaces.)

Understanding the LEDs
There are 9light–Emittinq Diodes (LEDs) on the system.Five are visible from
the front of the system uni~when the hinged door is closed, as shown in Figure
Figure 1– 3. The green LED on the far right is the Power LED. It lights when the
systemunit power is on. The remaining four amber LEDs show thatthe systemis
running the operating system and communicating over the network.

System 1/0 Connectors
●HP —HIL connector
●HP parallel 1/0 connector
●802.3 network connectors
.RS —232 serial input/output connectors
HP-HIL connector
The onboard Hewlett–Packard Human Interface Link (HP–Hil) port provides
support for 2standard and 5optional HP-Hil devices. The (two– dot) HP–HIL
connector on the bulkhead supports the standardHP– HIL keyboard. The key-
board provides an HP–HIL connector for the standard HP–HIL 3–button
mouse. Consult the documentation that accompanies each input device for specific
information concerning itsuse.
HP Parallel 1/0 connector
The 25 –pin HP Parallel 1/0 interface port isprovided for use with peripheral de-
vices using the Centronics interface protocols such as printers and plotters. Con-
sultthe documentation that accompanies each peripheral device for specific infor-
mation concerning itsuse.
Network connectors
The system provides aconnector for LAN through aremovable daughter card of
the system 1/0 board. Three LAN options are available: aBNC connector for a
ThinLAN IEEE 802.5 network. an AUI externalconnector for aMAU to an IEEE
802.3 network. or aconnector for an FDDI network.
1-8 Product Information

RS-232 Serial Input/Output connectors
You can attach avariety of peripheral devices to the two RS–232 Serial Input/
Output (S10) ports on the workstation. These peripheral devices include printers,
plotters, modems. and scanners. Consult the documentation that accompanies
each peripheral device for specific information concerning itsuse.
Both S10 ports are programmable. You can set functions such as bit rate, character
length, parity, and stop bits. S10 Ports 1and 2are used as interfaces for serial
asynchronous devices to the CPU. Both ports operate at up to a19.2K baud rate.
The interface to S101 and 2is by way of RS –232 drivers and receivers.
Table Table 1–2shows the S10 connector pin listings.The serial connectors are
9–pin D–sub connectors. Signalnames are those specified in the EIA RS–252

Audio connectors
The workstation has audio input and output capability through externalinput and
output connectors and an internal speaker. Amicrophone for audio input is not
supplied with the workstation. The audio connectors are standard audio mini—
jacks. Hewlett–Packard recommends that for best quality recording and playback
of audio through the externalconnectors, that you use gold–plated plugs available
through audio retailers. For more information on the audio capability of the work-
station see theAudio Users Guide manual. Figure 1– 6 shows the audio connectrs
on the rear of the workstation.
