SYSTEM OVERVIEW

1.2 MAJOR UNITS
The following subsections describe the VAX 4000 system’s major units
and their functions. A full description on how to use the system and
options can be found in the VAX 4000 Model 300 Operation manual.

1.2.1 System ON/OFF Switch
The main system ON/OFF switch is located in the upper left-hand corner
of the front panel (see Figure 1-1). This switch is the main power switch
for the entire system.

1.2.2 Mass Storage Shelf
The mass storage shelf extends across the front of the enclosure. The
shelf contains a System Control Panel (SCP), optional TK70 tape drive,
and up to three RF-series ISEs (tapeless systems can have up to four RF-

series ISEs). Each ISE has its own panel with controls and indicators.

Instructions for using ISEs and the TK70 tape drive can be found in the
VAX 4000 Model 300 Operation manual. The SCP is to the left of the

storage devices. Figure 1-3 shows the mass storage shelf.

SYSTEM OVERVIEW

The SCP has two indicators: the DC OK light and the Over Temperature
Warning light. The green DC OK light indicates that the power supply
voltages are within the correct operating range. If the DC OK light is

not lit when the system power is on, check the system ON/OFF switch on
front bezel (refer to Section 1.2.1) and the circuit breaker on the power

supply, then refer to the VAX 4000 Troubleshooting and Diagnostics

manual (EK-386AA-TS).

The red Over Temperature indicator flashes to indicate that the system’s
internal temperature is approaching a level that may cause system
components to overheat. In addition to the flashing Over Temperature

Warning light, an audible alarm also provides warning of a possible
over temperature condition. If the components continue to heat, the
system will automatically shut down to prevent components from being
damaged. Instructions for turning on the system after a preventive
shutdown due to overheat conditions are covered in more detail in the
VAX 4000 Model 300 Operation manual (EK-336AB-OP).
Below the indicators are the Halt and Restart buttons. The Halt button
1s a two-position button. When you press the button, the system halts. A

red indicator on the Halt button lights when the button is set to the "in"
position. Before you can enter console commands, press the Halt button
again to return it to the "out” position. When the Halt button is returned
to the "out" position, the console mode prompt >>> is displayed on the
console terminal screen. Now you can enter console commands. If you
inadvertently press the Halt button, type “c <key>(Return)” to continue.
The VAX 4000 Model 300 Operation manual (EK-336AB-OP) describes
halting the system in more detail.
CAUTION
Pressing the Halt button halts the system regardless of
the setting of the Break Enable/Disable switch on the
console bulkhead assembly.

Below the Halt button is the Restart button. The Restart button has a
green indicator. When you press the Restart button, the system returns
to a power-on condition and self-tests are run. If you have specified a
device as the boot device and if the Break/Enable Disable switch is set to
disable, the system will reboot system software. Further instructions on

restarting your system are covered in the VAX 4000 Model 300 Operation
manual (EK-336AB-0OP).

SYSTEM OVERVIEW

1-7

NOTE
The Halt and Restart buttons can be disabled to prevent
accidental activation. Contact your Digital service rep-

resentative if you want to disable the controls on the
SCP.

1.2.3 Card Cage
The modules in your system are mounted in a 12-slot card cage behind
the mass storage shelf, as shown in Figure 1-4.
The first four slots are reserved for memory modules. The fifth slot is
reserved for the CPU. A console bulkhead assembly with system controls
and connectors covers these first five slots. Slots 6 through 12 are
available for Q-bus option modules.
The number and type of modules installed in your system depend on
your configuration. Each Q-bus slot, even an empty one, is protected
by a module cover. Together the covers form a shield with a three-fold
purpose:

1-8

To protect external devices from electrical interference generated by
the system.

To protect the system from electrical interference generated by external devices.

To maintain air flow integrity.

SYSTEM OVERVIEW

Figure 1-4:

SYSTEM OVERVIEW

1-9

CAUTION
Do not operate the system without Digital-supplied mod-

ule covers. The covers are required to protect the equipment and to meet international regulatory standards. Do
not substitate other module covers, as they may not meet
the required specifications.
Operating the system without the module covers has the
following consequences:

The system may overheat due to improper air circulation.

The system will not comply with FCC and VDE requirements for electrostatic shielding and may produce electrical interference that affects other equipment.

The system is susceptible to electrical interference
or damage from external sources.

The design of the module covers varies, depending on the type of module

installed in the slot. Modules requiring external cable connections such
as communications controllers have recessed covers that are riveted

directly to the module. The recessed module covers allow space for
connecting cables. Modules requiring no external cable connections such
as mass storage controllers are covered by flush covers. Empty slots are

also covered by flush covers, which may be single or double width. All
covers, except those covering empty slots, have a label identifying the
module installed in the slot.
Cables connecting your system to peripheral devices (such as terminals,
modems, and printers) are attached to communications controllers. Each
cable can contain multiple lines. The cables run over the top of the BA441
enclosure and towards the back, where the cables are split into individual
lines. These connections are described in more detail in the VAX 4000
Model 300 Operation manual (EK-336AB-OP).

1-10

SYSTEM OVERVIEW

1.2.4 Console Bulkhead Assembly
Your system can have up to four memory modules. The memory modules
occupy the first four slots of the card cage and are followed by the CPU.

The memory and CPU modules are below the consele bulkhead assembly
that covers the first five slots. The console bulkhead assembly, shown in

Figure 1-5, has several system controls and indicators.
NOTE

These components are visible when the chassis is extended and viewed from the top (see Figure 1-§).

CONNECTORS

SYSTEM OVERVIEW

1-11

The console bulkhead assembly has the following components.
Power-On Mode switch — This three-position rotary switch

determines how the system responds at power-on:

Language Inquiry Mode (in the top position, indicated
by a profile of a face) causes the system to display a language selection menu at power-on if your console terminal supports multiple languages. Also, if a default
boot device has not been selected, this mode causes the

system to issue a list of bootable devices and prompts
you to select a device from the iist. Once a device is

selected, the system autoboots from that device each
time you turn it on.

Run Mode (in the middle position, indicated by an
arrow) is the normal operating setting.

Loop Back Test Mode (in the bottom position, indicated
by a T in a circle) causes the system to run loopback
tests on the console serial line at power-on.

This

setting requires special loopback connectors and is for

Digital Customer Services use only.
Baud Rate Select switch — The Baud Rate Select switch is

used to set the system’s baud rate to match that of the console
terminal. The factory setting is position 5 (9600).
Modified Modular Jack (MMJ) — This console terminal connector provides the connection for the console terminal.

The Light-Emitting Diode (LED) display shows the testing
sequence during power-on.

1-12

SYSTEM OVERVIEW

Break Enable/Disable switch — When the switch is down (position O), breaks are disabled. When the switch is up (position I), breaks are enabled. When breaks are enabled, pressing
<key>(Break) on the console terminal halts the processor and
transfers control to the console program.

Using the console
command SET CONTROL, you can specify the control charac-

ter <key>(Ctrl/C) rather than <key>(Break) to initiate a break
signal.
The Break Enable/Disable switch also controls what happens
at power-on. When breaks are disabled (down, position O), the
system attempts to automatically boot software at power-on.

When breaks are enabled (up, position I), the system enters
console mode (indicated by the >>> prompt) at power-on.
Using the console command SET HALT REBOOT or SET
HALT RESTART REBOOT, you can set your system to automatically boot software after the system is halted by pressing
<key>(Break).

Bus node ID plugs — VAX 4000 systems have two separate
Digital Storage System Interconnect (DSSI) buses. Two DSSI
bus node ID plugs, one for the internal DSSI bus (Bus 0) and
one for the external bus (Bus 1), identify the bus node to the
CPU. These plugs are configured at the factory. For single-host
systems, Bus 0 is identified as bus node 6, bus 1 is identified
as bus node 7; for dual-host systems, both buses on the first
host are identified as bus node 7, and both buses on the second
host are identified as bus node 6.

SYSTEM OVERVIEW

1-13

DSSI connectors (DSSI Bus 1) — Two Digital Storage System
Interconnect (DSSI) connectors, labeled X and Y on the console bulkhead assembly, allow you to expand your system by
connecting additional mass storage devices to the second DSSI
bus.

fi two Ethernet connectors: a BNC-type connector for ThinWire

Ethernet connectors — The console bulkhead assembly has
Ethernet, and a 15-pin connector for a standard Ethernet
transceiver cable. The Ethernet connector switch allows you
to set the type of connection. To use the standard transceiver
cable connection, set the switch to the up position. To use
the ThinWire cable connection, set the switch to the down
position. A green indicator light (LED) for each connector
indicates which connection is active.

1-14

SYSTEM OVERVIEW

1.2.5 DSSI and SCSI Connectors (DSSI Bus 0; SCSI Bus 0)
To the right of the card cage are the DSSI and SCSI connectors for
their respective Bus 0. Bus 0 provides the DSSI and SCSI bus for ISEs
installed in the system enclosure. The connectors allow you to expand
your system by connecting additional mass storage devices to the bus.
You can also share mass storage devices with a second system by forming

a dual-host configuration. Figure 1-6 shows the locations of the DSSI
and SCSI connectors for Bus 0.

1.2.6 Power Supply Controls and Indicators
To the left of the card cage is the power supply. The power supply
provides power to the mass storage devices, the modules installed in
the card cage, and the fans.

To prevent damage due to overheating, the power supply monitors the
internal temperature and the speed of the fans. If the power supply
detects overheating or a fan failure, the power supply will shut down the
system.

Figure 1-7 shows the controls and indicators on the power supply.
NOTE

These controls and indicators are visible when the chasgis is extended and viewed from the top (see Figure 1-7).

SYSTEM OVERVIEW

The controls and indicator lights function as follows:

:(\]

Power supply circuit breaker — This power supply drcuit
breaker is used to turn the power supply on and off. The OFF
position is indicated by a O; the ON position is indicated by a
1

NOTE
The power supply circuit breaker must be in
the "T" position at all times.

In the event of a power surge, the breaker will trip, causing
the system ON/OFF switch to return to the OFF position (O).
Turning the system ON (I position) resets the circuit breaker.
If the circuit breaker trips, wait one minute before turning the
system back ON.
AC Present indicator — The orange AC Present indicator
lights when the system ON/OFF switch and power supply
circuit breaker are set to ON and voltage is present at the

input of the power supply. If the AC Present indicator does
not light when the ON/OFF switch and power supply circuit
breaker are set to ON, refer to the VAX 4000 Troubleshooting
and Diagnostics manual (EK-386AA-TS).

DC OK — When the green DC OK indicator is lit, the power
supply voltages are within the correct operating range. If
the DC OK indicator does not light when the power switches
are set to ON, refer to your VAX 4000 Troubleshooting and
Diagnostics manual.

SYSTEM OVERVIEW

1-17

Fan Failure indicator — The amber Fan Failure indicator
lights if either of the two cooling fans stop working. The
power supply will automatically shut down the system as a
precautionary measure when a fan failure is detected. Call
your Digital service representative if a fan failure occurs.

Over Temperature Condition indicator — The amber Over
Temperature Condition indicator lights if the enclosure has
shut down due to an over temperature condition.
Power bus connectors — There are three power bus connectors.

Two of these power bus connectors (MO and SO) allow you to
configure a power bus for systems expanded with the R400X

expander.

The power bus allows you to turn power on and

off for one expander through the power supply designated
as the main power supply: this way, one power switch can
control power for an entire expanded system. The third power
bus connector (SI) is used to connect to the system’s ON
/OFF switch, enabling you to turn the system on from the
front panel. Therefore, the SI connector is not available for
system expansion. Figure 1-8 illustrates a possible power bus
configuration for an expanded system.
NOTE

Dual-host systems should not be configured with a power
bus. Inadvertently shutting off a host systemn defeats the

added reliability of a dual-host system.

1-18

SYSTEM OVERVIEW

The main out (MO) connector sends the power control
bus signal to the expander. One end of a power bus
cable is connected here, the other end 15 connected to
the secondary in (SI) connector of an expander power

supply.
Sl

The secondary in (SI) connector receives the power bus
control signal from the main power supply. In a power
bus with more than one expander, the power control
bus signal is passed along, using the secondary in and
out connectors shown in Figure 1-8.
NOTE

The SI connector is not available for system expansion.

The secondary out (SO) connector sends the signal

down the power bus for configurations of more than
one expander.

1.2.7 Fans
Two fans located behind the card cage draw air in through the front of the
chassis, through the card cage, and out the rear. The speed of the fans
varies, depending on the surrounding room temperature. To reduce the
load on the fans, keep the system away from heat sources. Figure 1-9
shows the air flow through the system enclosure.
NOTE
The power supply monitors the fans. If either fan stops
working, the Fan Failure indicator on the power supply lights, and the system automatically shuts down as a
precautionary measure. Call your Digital service representative if a fan fails.

The fan speed control can be set so that the fans will run
at their maximum speed. This setting is recommended
if you want potentially higher system module reliability,
and do not object to the increased fan noise. Contact
your Digital service representative to override the fan
speed control.

INSTALLATION

2.6.1 Connect Terminals and Serial Printers
You can connect up to 16 terminals and/or serial printers for each CXA16

or CXB16 module installed in the system. If the site has been prepared
properly, the lines for the additional terminals and printer(s) are clearly
labeled, and terminate near the system.

You do not connect the terminals and printers directly to the system, but
to a cable concentrator (H3104), which has connections for up to eight
terminals and printers. You then connect the cable concentrator to the
system with a BC16D cable. Two H3104 cable concentrators and two
BC16D cables for each CXA16 module are shipped with the system.

Connect the additional terminals and printers as follows:
1.

Find the H3104 cable concentrator and BC16D cable.

Feed one end of the BC16D cable under the system box from the back
or side and insert it into the connector. If you are going to connect

both BC16D cables, connect the first to the connector labeled 8-15
on the CXA16 module cover. If you are going to use only one BC16D
cable, connect the cable to the connector labeled 0~7. Lock the
connector into place by using the bail latches shown in Figure 2-9.
3.

Insert the other end of the BC16D cable into the cable concentrator.
Lock the connector into place by using the bail latches.

Connect each printer and terminal cable directly to one of the modified modular jacks on the cable concentrator, as shown in Figure 2-10.

If you have not already done so, connect the remote terminal or
printer to the other end of the cable.
The terminal or printer
documentation shows how to connect the cable. If the printer or
terminal does not have a modified modular jack connection, use a
passive adapter (H8571-A), availabie in 25- and 9-pin medels.

Follow the same procedure for connecting a second BC16D cable to the

CXA16, except insert the cable into the connector labeled 0-7.

INSTALLATION

2.6.3 Connect Synchronous Modems to the System
You can connect two synchronous modems to the system for each DSV11
module installed in the system.
Connect a synchronous modem to a DSV11 module using the protocol-

specific adapter and extension cables as follows:
1.

Feed the socket end of the 0.6 m (24 in) adapter cable (BC19-B/~D/~
E/-F) under the system unit from the back or side and connect it to
the DSV11 module. Tighten the two screws on the cable connector
using a screwdriver.

Connect the extension cable (BC55D, BC22F, or BC19L) to the other
end of the adapter cable. Secure the cables by tightening the two
screws at the connection.

Connect the other end of the extension cable to the modem. Refer to
the modem documentation for the location of the connector, and for
instructions on using the modem.

2.6.4 Connect Asynchronous Modems to the System
You connect asynchronous modem lines to the CXY08 module, which
supports up to eight lines. To connect a modem to a CXY08 module, see
Figure 2-12 and refer to the following instructions:
1

Find the BC19N-12 cable.

Feed one end of the cable under the system and insert it into the
connector. If you are going to use both BC19N-12 cables, connect

the first to the connector labeled 4-7 on the CXY08 module cover. If
you are going to use only one cable, connect the cable to the connector

labeled 0—3. Lock the connector into place with the bail latches.
Attach a modem to one of the four connectors at the opposite end of
the cable. If you want to place the modem farther away from the
system, attach a BC22F modem cable between the cable assembly
and the modem. Refer to the modem documentation for the location
of the connector, and for instructions on using the modem.
Repeat the same procedure for connecting a second BC19N cable, except
insert the cable into the connector labeled 0-3.

mounted modular telephone jgck, as shown in Figure 2-16.

If you require voice communication on modem A, refer to step 4 for
more information.

If you do not plan to use modem B, skip this step and proceed to step
4. If you plan to use modem B, connect a second 8-wire telephone
line to the bottom jack on the DFAO1 module cover, marked with
a line icon. (Notice that the jack positions are reversed for modem

B.) Connect the other end of the cord to a wall-mounted modular
telephone jack.

If you require voice communication on modem B, refer to step 4 for
more information.

If you require voice communication with the DFAO1 modem, you may
want to consider this step.

You can install voice communication on the DFAO1 modem in one
of two ways. Depending on the location of your system, telephone,
and wall-mounted modular telephone jacks, one of the following two
methods of installing voice communication may be more appropriate
for your system.

INSTALLATION

2-35

The first way of installing voice communication is established for
both modem A and modem B in the preceding steps. The telephone
is connected to the wall-mounted modular telephone jack which, in
turn, is connected io the DFAO1 module cover (see Figure 2-16).

Setting Up Terminal l.ines
Before you can use the DFAO]1 modem, you must set up the operating
system software to recognize the DFAO1 modem.
Set up the operating system software to support the following four
terminal lines for the DFAO1 modem:
Modem A—primary channel
Modem A—on-line control channel (OLC)

Modem B—primary channel
Modem B—on-line control channel (OLC)

Refer to the operating system documentation to determine how to make
permanent terminal line definitions so that every time the system is
powered up, the terminal lines are configured for proper operation.

You may need to define the following terminal line characteristics.
Modem control—to support full EIA modem control.

Speed, parity, data bits—terminal lines should be set to 2400 baud,
parity disabled, and 8 data bits to coincide with the modem power-on
defaults.
Dial up—to support dial-up operation.
Hang up—to disable automatic hang up of the lines when logging

out, or when completing a dialogue with the modem using terminal
emulation software. With automatic hang up disabled, you can
modify the DFAO1 modem operating parameters (from applications
software or when using a terminal emulator). You can then exit the
program without the DFA(01 modem resetting these parameters to
power-on default values.

2.8 COMPLETING INSTALLATION
This chapter describes the final procedures to complete the installation
of the VAX 4000, Model 300 Computer System.

2.8.1 Turn on the System and Select a Language
You are now ready to turn on the system and select a language. The
language you select controls only the language of the critical system
messages in the console program, which is part of the firmware contained
in the CPU. The CPU firmware enables you to give commands to the

system, and also generates error messages. CPU firmware is described
in the VAX 4000 Model 300 Technical Information manual.

Turn cn the system(s) and select a language for each as follows:

NOTE
You must choose a language separately for each system
.

in a dual-host system.

Turn on the console terminal and wait until it has performed its
self-tests successfully.

Turn on the system by setting the power supply circuit breaker
and the system ON/OFF switch to position ON (I). The AC Present

indicator, located on the power supply, will glow orange.
3.

Within a few moments, the Language Selection Menu is displayed
on the console terminal, as shown in Figure 2-34.

4. Select a language by typing the number corresponding to your choice
and pressing <key>(Return).

After you select a language, the system runs power-on self-tests. Within
a few moments, the console terminal should display a series of numbers

as the system tests itself. The example in Figure 2-35 shows the screen
after a successful power-on test.

If the self-tests do not start or complete successfully, as shown in
Figure 2-35, the system may have a problem. For instructions on finding

the source of the problem, refer to the VAX 4000 Troubleshooting and

Diagnostics manual.

2.8.2 After Installation
While optional, Digital strongly recommends that you run the diagnostic
software before you install system software or start factory-installed
VMS software for the first time. The diagnostics verify the system’s
configuration and check to see if each device is working properly. The
diagnostic software is on a tape cartridge labeled MV DIAG CUST TK50.
Chapter 3 of the VAX 4000 Troubleshooting and Diagnostics manual
describes how to run the diagnostic software.
If you have VMS Factory-Installed Software (FIS) on your system, refer

to Appendix A of the VAX 4000, Model 300 Installation manual for the
startup procedure.

Otherwise, install the system software that comes

with your system.
NOTE
Systems that come with Factory-Installed Software (FIS)
have s yellow sticker on the front panel of the ISE
containing the FIS.

You should now read the VAX 4000 Model 300 Operation manual to
learn how to use the system. You must know how to operate the system

controls and the ISE before you install system software or run diagnostic
software.
For more information on dual-host systems, refer to your VAX 4000 Model
300 Operation manual and to the VAX 4000 Dual-Host Systems Manual.
