The red over-temperature indicator flashes when the internal temperature approaches a level that may cause system components to overheat.
An audible alarm also provides a warning of a possible over-temperature
condition. If the components continue to heat, the system automatically
shuts down to prevent component damage. Instructions for turning on
the system after a preventive shutdown due to overheat conditions are
covered in the VAX 4000 Operation manual.
Below the indicators are the Halt and Restart/Run buttons.

The Halt

button is 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]

to continue.

The VAX 4000 Operation manual 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/Run button. The Restart/Run
button has a green indicator. When you press the Restart/Run button,
the system returns to a power-on condition and self-tests are run. If
you have a boot device and if the | /O (break/enable disable) switch (see
Figure 1-5) is set to O (disable), the system will reboot system software.
Further instructions on restarting your system are contained in the VAX
4000 Operation manual.
NOTE
The Halt and Restart/Run buttons can be disabled te prevent accidental activation. Contact your Digital service
representative if youn want to disable the controls on the
SCP.

1.2,1.3 System ON/O=* Switch

The main system ON/OFF switch is located in the upper left-hand corner
of the front panel (see Figure 1-3). This switch is the power switch for
the entire system.

1.2.2 Card Cage
The modules in your system are mounted in a 12-slot card cage behind
the mass storage shelf, as shown in Figure 1-6. The slots are numbered
beginning with slot one next to the power supply.
A console bulkhead assembly with indicators, system controls, and
connectors covers the memory modules and CPU in the first five slots.
1.2.2.1 Memory Modules

The first four slots are reserved for memory modules.
1.2.2.2 CPU

The CPU is 1n the fifth slot.
1.2.2.3 Q-bus Option Modules

Slots 6 through 12 are available for Q-bus option modules (see Figure 1-7). 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 cover. Together these covers and the console bulkhead
assembly form a shield with a three-fold purpose:
1.

To protect external devices from electrical interference generated by

the system, maintaining compliance with FCC and VDE requirements.

To protect the system from electrical interference generated by ex-

ternal devices.
3.

1-10

To maintain airflow integrity.

CAUTION
Do not operate the system without Digital-supplied slot

covers. The covers are required to protect the equipment
and to meet interpational regulatory standards. Do not

substitute other slot covers, as they may not meet the
required specifications.

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 ne 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
enclesure and towards the back, where the cables are split into individual
lines. These connections are described in more detail in the VAX 4000

Operation manual.
1.2.2.4 Console Bulkhead Assembly
The console bulkhead assembly (see Figure 1-8) covers slots 1 through
5, and has several system controls, indicators and connectors.
NOTE
The console bulkhead assembly is visible when the chassis is extended and viewed from the top (see Figure 1-8).

The console bulkhead assembly contains the following controls and
indicators:

o @

Power-Up mode switch — This three-position rotary switch

determines how the system responds at power-up:

Language inquiry mode (the position indicated by a

profile of a face) causes the system to display a lan-

guage selection menu at power-up 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 list. Once a device is
selected, the system autoboots from that device each
time you turn it on.

Run mode (the position indicated by an arrow) is the
normal operating setting.

Loup back test mode (the position indicated by a T it 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 — This switch sets the system baud

° {1

rate to match that of the console terminal. The factory setting

Modified modular jack (MMJ) — This console terminal connec-

(@)

is position 5 (9600).

tor provides the connection for the console terminal.

Light-emitting diode (LED) — This display shows the testing

processor and transfers control to the console program. Using

the console command SET CONTROL, you can specify the
control character
rather than
to initiate a break
signal.

The break enable/disable switch also controls what happens at
power-on. When breaks are disabled (down or O position), the
system attempts to automs* cally boot software at power-on.
When breaks are enabled (up or | position), 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

Bus node ID plugs — VAX 4000 systems have two separate

o @

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.

DSSI connectors (DSSI Bus 1) — These two 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.

Ethernet connectors — The console bulkhead assembly has
two Ethernet connectors: a BNC-type connector for ThinWire
Ethernet, and a 15-pin connector for a standard Ethernet
transceiver cable.

1-16

Ethernet connector switch — This switch selects either the

ThinWire or the standard Ethernet connection. To use the

standard connection, set the switch to the forward position.
To use the ThinWire cable connection, set the switch to the

Rack-Mountable VAX 4000 Model 400/500/600 System Querview

back position. A green indicator light (LED) for each connector
indicates which connector is active.

1.2.3 DSSI and SCSI Connectors (DSSI Bus 0; SCSI)
To the right of the card cage are the DSSI and SCSI In connectors (see
Figure 1-9) for their respective Bus 0. Bus 0 provides the DSSI 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.

1.2.4 Power Supply Controls and Indicators
To the left of the card cage is the power supply (see Figure 1-10), which
provides power to the mass storage devices, the modules installed in the
card cage, and the fans.
To prevent damage from 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 shuts down the
system.

Figure 1-10 shows the controls, indicators, and connectors on the power

supply.
NOTE
These controls, indicators, and connectors are visible
when the chassis is extended and viewed from the top
(see Figure 1-10).

The controls, indicators, and connectors function as follows:
Power supply circuit breaker — This switch is used to turn

the power supply on and off. The OFF position is indicated by
a O; the ON pogition is indicated by a |.
NOTE
To operate the VAX 4000, the power supply

circuit breaker must be in the ON ( | ) position.

A power surge will cause the breaker to trip and set the systein

ON/OFF switch to the OFF position (O). Setting the systern ON
/OFF switch to ON ( | ) resets the power supply circuit breaker.

If the circuit breaker trips, wait one minute before setting the
system ON/OFF switch to ON.

AC present indicator — This 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.
DC OK indicator — This indicator lights when 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.

Fan failure indicator — This indicator lights if either of the two
cooling fans stop working. The power supply automatically
shuts down the system as a precautionary measure when a fan
failure is detected. Call vour Digital service representative if

a fan failure occurs.
Over-temperature condition indicator — This amber over-

°%

temperature condition indicator lights if the enclosure has
shut down due to an over-temperature condition.

Rack-Mountable VAX 4000 Model 400/500/600 System Overview

1-21

o@|

Power bus connectors — There are three power bus connectors

MO, s0, and SD.

The main-out (MO) connector is the source for the
power control bus signal to the expander. One end
of a power-bus cable is connected here and the other
end is connected to the power supply secondary-in (SI)
connector of an R400X expander.

In the VAX 4000, the secondary-in (SI) connector receives the power bus control signal from the front panel
system ON/OFF switch. In a power bus with more
than one expander, the power control bus signal is connected between expanders using the secondary in and
out connectors (see Section 2.7.4)
NOTE

The SI connector is not available for system expansion.

The secondary-out {S0) connector is not used on the
VAX 4000 system. It is used to send the signal down
the power bus for configurations with more than one
expander.

1-22

Rack-Mountable VAX 4000 Model 400/500/600 System QOuverview

1.2.5 Fans
Two fans, located behind the card cage, draw air in through the front
of the VAX 4000 chassis, through the card cage, and out the rear of the
VAX 4000. The speed of the fans varies, depending on the ambient room
temperature. To reduce the load on the fans, keep the system away
from heat sources. Figure 1~11 shows the airflow through the VAX 4000
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 magimum speed. This setting is recommmended
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.

CAUTION
Do not operate the system without Digital-supplied slot
cuvers. These covers are required to protect the equipment and to meet international regulatory standards. Do
not substitute other covers as they may not meet the re-

quired specifications.
Operating the system without the slot covers has the
following consequences:

The system may overheat due to inadequate air circulation.

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

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