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 Model 5004 /600A /700A 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
System Querview

on the console terminal screen. Now you can enter console commands. If

you inadvertently press the Halt button, type [¢][Return] to continue. The

VAX 4000 Model 500A/600A/700A Operation manual describes halting
the system in more detail.
CAUTION
Pressing the Halt button halts the syst sm regardless of
the setting of the break emable/disabie 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 Model 500A/600A/ 700A Operation manual.
NOTF
The Halt and Restart/Run buttons can be disabled to prevent accidental activation. Contact your Digital service

representative if you want to disable the controls on the
SCPI

1.2.1.3 System ON/OFF Switch

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

To protect external devices from electrical interference generated by
the system, maintaining compliance with FCC and VDE requirements.

System Overview

CAUTION
Do not operate the system without Digital-supplied slot
covers. The covers are required to protect the equipment

and to meet international 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 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,
moedems, 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 500A /600A/700A 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 chas.
sis is extended and viewed from the top (see Figure 1-8).

System Querview

The console bulkhead assembly contains the following controls and
indicators:

°©

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 langr.age selection menu at power-up if your console terminal suports multiple languages. Also, if a default

}

boot deviie 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 arr: v) is the
normal operating setting.

Loop back test mode (the 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 — This switch sets the system baud
rate to match that of the console terminal. The factory setting
is position 5 (9600).

Modified modular jack (MM.J) — This console terminal connector provides the connection for the console terminal.

Light-emitting diode (LED} — This display shows the testing
sequence during power-up.

System Querview

1-15

Break enable/disable switch — When this switch is pushed
back (down or O position), breaks are disabled. When it is
forward (up or | position), breaks are enabled. When breaks

break signal.
The break enable/disable switch also controls what happens at
power-on. When breaks are disabled (down or O position), the
sysiem attempts to automatically 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 1is halted by

pressing [Break].
Bus node ID plugs — VAX 4000 systems have two separate
DSSI buses. Two DSSI bus node ID plugs, one for the internal

DSSI bus (Bus 0) and vne 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

(=3l

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.

1-18 System Overview

1.2.4 Additional DSSI Buses
The system can have up to four Digital Storage System Interconnect

(DSSI) adapters. If the system has four DSSI adapters, two are built into
the CPU, and two are installed on the DSSI bus daughter board, which
is connected to the CPU module. They provide a path to four separate
DSSI buses (0, 1, 2, and 3) through which the CPU can communicate
with DSSI devices.

Each adapter can support eight nodes, with the adapter and each DSSI
storage device counting as one node. Therefore, each adapter can support
seven DSSI storage devices.

The adapters also let you link one of the DSSI buses to another system to
form a DSSI VAXcluster configuration, described in the VAX 4000 Model
500A /600A | 700A Operation manual. When a DSSI bus is extended to a
second system, both systems can share up to six DSSI storage devices.
When a DSSI bus is extended to a third system, the systems can share
up to five DSSI storage devices.
When the system is configured with four DSSI buses, slots 6 through 12

will be configurated in the following ways, depending on if the system
contains expansion enclosures:
¢

If the system does not contain expansicn enclosures (see Figure 1-10,
insert A):

Slots 6 through 10 are available for Q-bus option modules.

1.2.5 Power Supply Controls and Indicators
To the left of the card cage is the power supply (see Figure 1-11), 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 1-11 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 1-11).

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 position is indicated by a | .
NOTE
To aoperate 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 system
ON/OFTF switch to the OFF position (O). Setting the system 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 Model 500A/|600A / 700A 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 the VAX 4000 Model 500A /600A [ 700A
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 your 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.

System Overview

1.2.6 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, dependiug on the ambient room

temperature.

To reduce the load on the fans, keep the system away

from heat sources. Figure 1-12 shows the airflow through the VAX 4000
system enclosure.
NZTE
The power supply monitors the fans. If either fan stops
working, the fan failure indicator on the power supply

lights, and the system automatically ehuts 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.

2.8.2 After Installation
Read your system operation manual to learn how to use your system.
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.
The VAX 4000 Model 500A/ 600A
| 700A Troubleshooting and Diagnostics
manual describes how to run the diagnostic software.
If you have VMS FIS (factory installed software) on your system, refer
to the VMS Factory Installed Software User Guide for the startup
procedure. Otherwise, install the system software that comes with your
