General Information

Model 743 and Model 744 VME Board Computers

Supported Configurations

This section discusses the following supported configurations: memory, system graphics,
external devices, cables, and keyboard and mouse.

Hewlett-Packard only supports products having Hewlett-Packard approved parts, accesso­ries, peripherals, operating systems, and application programs.

Model 743 Memory

Standard memory is Error Checking and Correcting (ECC) RAM cards. Up to four RAM
cards may be installed. RAM upgrades include:

• HP A4265A 32 MB RAM Card

• HP A4266A 64 MB RAM Card

Model 743 VME Board Computers use custo m 60-ns TSOP-based RAM card s. Use of TSOP
packaging allows adequate cooling in single-slot installations.

T wo stack location s for RAM cards a re used. The primary RAM stack is on t he right s ide, the
secondary one is on the left side. Only one RAM card can be used in the secondary, or left
stack, if a GSC+ card is ad ded i n t he s eco ndar y GSC+ s lot . Thr ee RAM ca rds can be used in
the primary stack. If more tha n one RAM card is use d in eith er stac k, the opti onal HP 4262 A
GSC Expansion Kit or A4504A PMC Bridge Adapter (HP-UX only) must be installed; then
the board computer will occupy two VME slots in a VME chassis.

RAM cards may be placed in any order. A higher density card can be added on top of a low
density card and vice versa.

Model 744 Memory

Standard memory is Error Checking and Correcting (ECC) RAM cards. Up to four RAM
cards may be installed. RAM upgrades include:

• HP A4501A 64 MB RAM Card

• HP A4449A 128 MB RAM Card

• HP A6005A 256 MB RAM Card

Model 744 VME Board Computers use custo m TSOP-based RAM cards. Us e of TSOP pack ­aging allows adequate cooling in single-slot installations.

There is only one stack l ocation f or RAM cards on the Model 744. Memory ca rds are st acked
in the same orientat ion; th at is, t here is no nee d to rot ate cards 18 0 degree s rela tive t o the pre­viously inserted card as in the Model 743. If more than one RAM card is used, the optional
HP 4219A GSC expansion kit must be installed; then the board computer will occupy two
VME slots in a VME chassis.

When mixing the 128 MB and 256 MB RAM card wi th c ar ds o f a different capacit y, the 128
MB and 256 MB card(s) must always be in the lower memory slots.

Boot ROM Circuit

The Boot ROM circuits have Boot ROMs containing 2x526 Kilobytes (Model 744) or 512
Kilobytes (Model 743) of information that does the following:

• Manages the internal interface configurations

• Searches for and boots an operating system

• Self-tests the board computer's main circuits

• Starts the CPU functions
An EEPROM stores the following information:

• Internal interface configurations

• LAN ID number

• System board serial number

NOTE: The workstation's LAN ID number's last 6 characters are labeled on the EEPROM. The first

group of six digits are typically “080009” or “0060b0” (the HP-owned prefix).
A PLL Clock Module generates the system clock, on which all timing is based.

Graphics Circuit

System boards with on-boa rd graphic s or graphi cs cards hav e a graphics cont roller ASI C and
the display RAM. Resolution and refresh rate can be configured using the boot console han­dler for several types of monitors.

A keyboard must be connected to the PS/2 0 port if graphics are used as part of the console
path. When a graphics device is specified as the console path, the boot ROM first checks for
a keyboard by using the keyboard search list. If a keyboard is not found in this search list,
graphics are not enabled.

Table 1-9 summarizes the graphics performance figures for the Model 743 with HP-UX and

General Information

Model 743 and Model 744 VME Board Computers

The sections that follow explain the functions of the interfaces.

Audio Model 743 and Model 744 Board Computers provide compact disc-quality audio

input and output, in stereo, with a 16-bit coder-decoder (CODEC) over a frequency range of
25-20,000 Hz. A stereo headphone mini-plug (8 ohms impedance) provides output. The ste­reo line-in and mono microphone mini-plugs provide input with the HP A4302A Audio
Cable.

The CODEC combines CD quality stereo A/D converters for microphone and line input lev­els. D/A converters for dri ving headset and line out puts are used. The input samp ling rate and
format are programmable, as are the input gain control (used for software control of record­ing levels) and output attenuation.

A

/8-inch mini-jack is used for the speaker out connection. The other audio signals are on a
9-pin micro D-sub connector. The output is capable of driving a minimum of 8 ohms. It can
also be used for higher impedance devices with little or no additional distortion.

A voice-quality audio output may be used.

AUI LAN LAN circuits use the Ethernet/IEEE 802.3 standard interface. Only the Attach-

ment Unit Interface (AUI) versi on is used ; no BNC connec tor is provi ded for ThinLAN. The
AUI connector enables connec tions to an exte rnal MAU using the HP A4303A adapt er cable.

Table 1-15 summarizes the LAN AUI interface specifications.

Single-Ended SCSI The 8-bit single-ended implementation is compatible with the current

Series 700 products and supports 5 MB/sec data transfer rates.
The SCSI bus is terminated to 3.3 volts through 127 ohms on the system board. If the board

computer is used in a VME chassis having internal mass storage devices, all devices except
the last one must have their terminator removed. If an external disk drive is used, an active
terminator must be used on the last drive’s uncabled connector.

Table 1-16 summarizes the specifications for the single-ended SCSI interface.

HP Parallel The parallel port is compatible with Centronics standards, plus some additional

features found in HP Series 700 workstations. It supports a bi-directional register model
interface. An 8-bit parallel, synchronous interface is used.

A high-density micro D-sub connector is used for the HP Parallel interface. An HP A4300A
adaptor cable is required to convert to standard PC compatible 25-pin female D-sub.

Table 1-17 summarizes the specifications for the HP parallel interface.

PS/2 Ports 1 and 0 There are two PS/2 style serial ports: one PS/2 keyboard port and one

PS/2 mouse port.

RS-232 There are two serial interfaces. The I/O controller ASIC controls port A, and the

VME controller ASIC controls port B. Each supports CTS/RTS hardware handshaking. An
HP A4301A adaptor cable is required to convert it to a standard PC compatible, 9-pin male
D-sub. The maximum baud rate listed in Table 1-18 is the hardware limit. Actual transfer
rates depend upon the operating system and application load.

Table 1-18 summarizes the specifications for RS-232-C.

NOTE: The RS-232 port B is not active until VME Services is up and running.

Battery-Backed Real-Time Clock The battery-backed clock is implemented in the I/O con-

troller ASIC. Once power is applied to the system board, the battery-backed clock time is
read by the operating system only during system initialization. Once the operating system is
booted, real time is kept by us ing the timer bui lt into the CPU. The battery-ba cked real-time

clock is updated by the operating system only when the user (“root” or “super-user”) explic­itly requests it though the date command. The clock has a resolution of 1 second. The accu­racy of the clock is wit hin ±5 seco nds every 24 hour s when the oper ating temper ature is from
0 to 55 Deg.C.

I/O Expansion

The Model 743 and Model 744 b oard c omputer s are capabl e of accep ting expansi on ada pte rs
allowing greater functionality through expansion I/O cards. The PMC bridge adapter (for
HP-UX systems only) occupies an additional VME slot directly above or adjacent to the
board computer, and has two sites for industry standard +5V signalling PMC cards. The
PMC expansion adapter occupies another VME slot adjacent to or above the PMC bridge
adapter, and provides two additional sites for PMC cards. The GSC expansion adapter has
two sites for GSC expansion cards, and occupies one VME slot adjacent to or above the
board computer. The PMC adapters and the GSC adapter cannot function together.

HP provides three GSC solutions for expanded I/O:

• 8-plane color graphics controller

• FWD SCSI controller

• ATM network controller

SCSI Interface The mass storage module has a SCSI connector for connecting ex ternal SCSI device
cables. When the external SCSI interface connector is not used, a SCSI terminator should be plugged
into the SCSI connector.

A cable from the mass storage module connects to the system board's SCSI connector and must be
connected for internal drives to operate. SCSI interface circuits use high-density, shielded connectors.
The internal cable length is 1.8 meters (5.9 feet).

The last device on each SCSI bus must be terminated. Internal drives d o not have terminators enab led.
The SCSI bus terminator(s) shipped with the Model 748 must be installed on the external bus connec­tor(s) if no external devices are connected. The single-ended terminator is par t number A165 8-6 201 6,
and the FWD terminator part number is A1658-63013.

Climatic and Dynamic Environmental Ruggedness

Climatic and Dynamic Environmental Ruggedness

The sections that follow summarize the climatic and dynamic environmental tests suites.

Introduction

Models 743, 744 and 748 are designed for use in an environment that involves moderately
high and low temperatures, humidity variations, and occasional vibration. Many of the test
limits the workst at ions are subjected t o dur ing development are more severe than t hose docu­mented.

The tests were developed to cause product failure so that product weaknesses are identified,
understood, and eliminated, when possible and to provide greater assurance of long-term
compliance to product specifications.

An effective qualification program establishes appropriate assurances. Our development and
manufacturing process capabilities are well understood.

Significant quantities of Models 743, 744, and 748 were tested prior to release for volume
production. Representative samples of customer-shippable workstations were tested in vari­ous configurations through the environmental tests to evaluate corner-case conditions.

NOTE: Presentation of these test suites does not imply a guarantee of product performance, nor a

guarantee of performance to these levels by the entire populat ion of Models 743, 744, an d 748
computer systems.

Statistical Reliability

Statistical Reliability

The sections that follow explain the Annualized Failure Rate (AFR) and the Mean Time
Between Failure (MTBF) computations.

Annualized Failure Rate Projections

Estimated 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.

Projected Failure Rat e is th e mature AFR, esti mated fr om the fail ure ra tes of the compon ents
of the product. The "E stima ted Long -Term Ann ualiz ed Fail ure Rat e" is a futu re proj ecti on of
an average realist ic fa ilure rate be yond the typi cal in fa nt fai lure pe riod th at occu rs i n the fi rst
few months of use and before long-term wear out, which occurs after many years of use.

Mean Time Between Failure Computations

The MTBF is the reciprocal of the AFR. MTBF uses the following two units of time:

• Annualized MTBF (A-MTBF), the time units are years, or annually.

• Hourly MTBF (H-MTBF), the time unit is the hour.

This is derived by fac to ri ng ou t t h e AFR' s a nnua li zed percentage, then finding its recipro cal .
A resultant A-MTBF term is in years.

Mounting and Support

Each Model 748 workstatio n is sh ipp ed with a rack mount ki t incl uding flange s, spac ers, an d
screws. In this s ect ion, the term "bac k" refers to the ca bl e-out side of the workstation. Model
748 satisfies three rack mount orientations:

• Mast mount

• Rack mount, either front out or back out
Power switching is ac ce ssi bl e fr om bot h f ron t an d bac k. A si ngl e p ower L ED is o n th e fr ont .

Status and te st LEDs are l ocated on t he Mo del 743 Mode l 744 VME Boa rd Computer s. If the
power supply and VME board computer LEDs must be visible, mount the workstation back
out. Devices within the mass sto rage module ca n be arr anged for front or back a ccessi bility.

• Wall mount
PCI/EISA and VME card cages are fixed and cannot be reversed.

Mechanical Drawings

For OEMs that have signed a Hewlett-Packard non-disclosure agreement, the mechanical
drawings are available by request from the Workstation Systems Group through your
Hewlett-Packard OEM Sales Representative. These drawings are Hewlett-Packard confiden­tial and cannot be redistributed.

When you ask for drawings, please specify the following:

• Drawing part number, size, and page number, if needed

• Name, assembly or subassembly
The drawings are sent to your Sales and Service Office.

Conversion Cables

All conversion cables are 762 plus or minus 30 mm (30 plus or minus 1.18 inch) long. The
end of the cable that connects to the board computer uses a micro D-sub male (MDSM) con­nector. The other end of the cable uses a standard D-sub or other connector.
