Built–In Interfaces
System Unit Interfaces
The system board’s built–in interfaces have ports on the workstation rear panel.
Audio Interfaces
The J Class workstations have audio input and output capability through external input and output
connectorsontherearpanelandthroughaninternalspeaker.TherearpanelcontainstheAudioIN(Stereo
line–in) and Mic (Mic–in), and Audio OUT (Stereo line–out) and Headphones (Headphone–out)
connectors.
The audio connectors are standard stereo audio mini–jacks. Hewlett–Packard recommends using
gold–plated plugs available through audio retailers for best quality recording and playback through the
external connectors. The following is a summary of the workstation audio features:

Programmable output attenuation:
0 to –96dB in –1.5dB steps
Programmable input gain:
0 to 22.5dB in 1.5dB steps.
Input monitoring:
16–bit linear, 8–bit u–law, or A–law coding
•Audio Inputs Line–in
Mono microphone compatible with 1.5V phantom supply
(bias voltage supplied by the system)

Keyboard Interfaces
The J Class workstation provides keyboard interfaces that allow either PS/2 or ITF keyboards. Consult
the documentation that accompanies each input device for specific information concerning its use.
PS/2 Keyboard Interfaces
The PS/2 connectors provide an interface for the keyboard and mouse to the system.
ITF Keyboard Interface
The HP HIL connector provides an interface for the ITF Keyboard to the system and all HP HIL devices.
HP Parallel I/O Interface
The 25–pin HP Parallel I/O interface uses Centronics interface protocols to support peripheral devices
such as printers and plotters. Consult the documentation that accompanies each peripheral device for
specific information concerning its use.

1-6 General Information J Class Technical Reference
Network Interface
The J Class has built–in ThickNet LAN AUI and TP (Twisted Pair) connectors for the 802.3
(ETHERNET) network. Connections to ThinLAN networks require an external transceiver. Your
workstation will autoselect the correct network setting.
The IEEE 802.3 Ethernet Local Area Network (LAN) circuit provides both the AUI interface for
conventionalcoaxial Ethernetand adirect interfaceto atwisted pair(TP) 10BASE–Tnetwork. Only one
built–in interface can be used at a time. The system auto–selects the correct port that is being used.
Ethernet is a 10 Mbit/s packet–switched serial interface employing Carrier Sense Multiple
Access/CollisionDetection(CSMA/CD). Table 1–3liststhesupportedLAN adaptersand othernetwork
devices.

HP 28673A 10:10 LAN Bridge
HP 28683A Fiber Optic Transceiver
RS–232 Serial I/O Interfaces
The RS–232 Serial I/O (SIO) ports on the J Class accept a variety of pointing devices or peripheral
devices. Peripheral devices include printers, plotters, modems, and scanners. Consult the documentation
that accompanies each peripheral device for specific information concerning its use.
The SIO ports are programmable, allowing the setting of such functions as bit rate, character length,
parity, and stop bits. SIO Ports are used as interfaces for serial asynchronous devices to the CPU. The
ports operate at up to a 19.2 K baud rate.
Table 1–4 shows the SIO connector pin listings. The serial connectors are 9–pin D–sub connectors.
Signal names are those specified in the EIA RS–232 standard.

Single–Ended SCSI–2
The built–in SCSI–2 port is implemented using an NCR710 macrocell inside the I/O ASIC chip. This
8–bit single–ended implementation is synchronous and compatible with the current 700 series products
and supports 5 MB/sec data transfer rates.
The SCSI bus is terminated to 3.3 volts through 127kΩon the CPU board. If an external disk drive is
used, an active terminator must be used on the drive at the end of the cable.
Fast, Wide Differential SCSI–3
Fast, wide SCSI is an extension to the existing 8–bit, single–ended SCSI. “Fast differential” indicates
thatsignals onthe SCSIbusaredifferentiallydrivenand terminated,andcapableof a10 MHzclock rate.
“Wide” indicates that there are 16 data bits on the SCSI bus.
Thefast,wideSCSIbusisspecified atapeaksynchronoustransferrateof 20MB/sec. Thearchitectureof
the fast, wide SCSI port on the J Class workstation has been designed to allow a 20 MB/sec sustained
transfer rate for long data streams.

Reliability
Estimated Annualized Failure Rate (AFR) is based on a parts count and the failure rates of those parts in
similar products. The AFR is estimated from the sum of the failure rates of the components’ assemblies.
A key assumption is that AFR is constant beyond the early life of the product and before long–term wear
out. Mean Time Between Failures (MTBF) is the reciprocal of the AFR. Table 1–10 shows the AFR and
MTBF of the J Class, with and without mass storage.
Table 1–10. AFR and MTBF
Product Configuration AFR MTBF
J Class 32 MB, no mass storage 22.0% 39,818
J Class 32 MB, with mass storage 25.5% 34,350
Projected Failure Rate is the mature AFR, estimated from the failure rates of the components of the
product. The “Estimated Long–Term Annualized Failure Rate” is a future projection of an average
realistic failure rate beyond the typical infant failure period that occurs in the first few months of use and
before long–term wear out which occurs after many years of use. These rates are for a full year and are
based on a 100% duty cycle.

can be removed from the front of the chassis without disconnecting any cables except the AC Line Cord
from the back of the system chassis.
Part Number: 0950–2497
Size: 434mm X 317mm X 90mm
Weight: 6 Kg
# of Connectors: 3 Output Connectors / 1 Input Connector
Type of Connectors: Output Connectors are Molex “Minifit” Blind Mate Input
Connector is IEC320 compatible
Power System Specification
The J Class Power Supply is 484 watts at 75% efficiency which delivers all the proper voltages to the
system. It contains two 80 mm fans designed to deliver the proper airflow to all sections in the system.
Powerisdistributedthrough“blindmate”interconnectsto thesystembackplane,minimizingthenumber
of internal power cables and easing manufacturing and field servicing of the system. The power system
budget is shown in Chapter 7 of this document. There are two voltage regulators on the system board.
One converts +5v to +2v and the second converts –12v to –3.2v. These two regulators provide power to
theclockcircuits. ThereisalsoavoltageregulatorontheEISAbackplanewhich converts–12vto–5vfor
EISA power. The system is turned On/Off via the front panel switch.
LCD Display Board
Thecontrolpanelmoduleisa16–characterx2–linedisplay.ThedisplayisconnectedtotheSystemboard
by a single 14–pin connector located directly in back of the Hitachi Module Board. Note that the J Class
implementation requires a special viewing angle part. The “industry standard” part is a 6:00 view as
implemented in a calculator. That optimizes a viewing angle looking from the bottom. The J Class part
optimizes a 12:00 viewing angle from the top.
