Physical Requirements
Table 1-1 lists the enclosures in which the systems and expanders covered
in this document are shipped. For simplicity, enclosure designations will
frequently be used throughout the document rather than the system or
expander name.

The physical requirements for VAX 4000 systems are determined by system
dimensions (both before and after the shipping carton has been removed),
space for cabinet doors to swing open, and space for peripheral computer
equipment such as printers and terminals, and allowances for adequate
airflow around the system and the noise emission level of the system.

1.1 When Your Shipment Arrives
When the system arrives, you should inspect it with a Digital service
representative to ensure that the system and all ordered options have
arrived undamaged.
When you are ready to begin installation, find the Customer Hardware
Information Kit and begin using the Installation manual to install your
VAX 4000 system. Also see the Installation Checklist.

Physical Requirements

1-1

1.2 Space Requirements
When planning cable routing for multiple-terminal equipment, you should
consider factors such as safety, convenience, future expansion, and cost.
The system installer has other special factors to consider when cabling
a multiple-terminal system on more than one floor in the same building,
or in more than one building. Digital offers several cable types for these
applications, and Digital service personnel are available to help you plan
your installation. Your sales representative can provide more information.

Before unpacking any equipment, make sure you have enough space to
remove the system from its shipping container. Also make sure you leave
enough space around the system so it can be serviced. The dimensions of
containers and enclosures are illustrated in Chapter 2.
You must leave at least 1 m (39 in) of clearance at the front of the system
for opening and removing the door and to access system controls. You must
also leave at least 5 cm (2 in) of clearance at the sides and rear for airflow.
Since the base of the enclosure is 5 cm (2 in) wider than the cabinet in front
and rear, you can place the rear of the system against a wall or table, and
the system will have enough room for adequate airflow.
Space for Additional Equipment and Cabling

In addition to the space required for the VAX 4000 systems and/or
expander(s), you should ensure that you have enough space for terminals,
printers, mass storage media, printer paper, and other necessary supplies.
If you plan to connect your system to peripheral devices such as printers,
terminals, or modems, you will need additional cabling. Cables that connect
the system to peripheral devices must be ordered separately.

NOTE: Cabling from peripheral devices should already be in place and
labeled before the system is installed.

1.3 Operating· Environment
Computer systems are affected by (or vulnerable to) the discharge of static
electricity, temperature changes, and humidity. These conditions can affect
the operation and overall dependability of the computer system.
Your system should be installed in a well-ventilated area where the
temperature and humidity ranges listed in Chapter 2 for your system are
maintained throughout the year. Rapid temperature changes may affect
system performance. Therefore, do not operate systems near heating or
cooling devices, large windows, or doors that open to the outside. Air should
contain a minimum of dust and other abrasive contaminants.

1-2 VAX 4000 Site Preparation

(

Mass storage media and other computer supplies, inclu.ding paper, should
be kept at the same temperature and humidity as that of the computer
area.

1.3.1 Static Electricity
Static electricity is a common problem for computer systems. It can cause
system failure and loss of data. The most common source of static buildup
is contact between people and carpeting or clothing. Low humidity allows
the greatest buildup of static charges.
To min~mize static buildup, follow these guidelines:

•

Maintain relative humidity of at least 40 percent.

•

Locate your system away from busy office corridors.

•

Avoid using carpeting in the computer area. If you install carpeting,
use antistatic carpeting, if possible. If carpeting is already installed,
place a grounded, antistatic mat under the system.

•

Maintain the antistatic properties of antistatic floors, carpeting, or mats
by following the manufacturer's recommendations for cleaning.

1.3.2 Temperature and Humidity Ranges
To function properly, each system and expander must operate in an
environment with acceptable temperature and humidity ranges.
To
determine the appropriate temperature and humidity ranges for your
system, refer to Chapter 2 and the specifications for your particular system.

When calculating the operating temperature in your computer environment, consider the heat that the system, peripherals, and other equipment
generate. See Chapter 2 for the amount of heat dissipated by each system
and expander.

1.3.3 Electrical Requirements
In determining the electrical requirements of a VAX 4000 system and
expander, consider the following:
•

What country the system is located in

•

Voltage range

•

Power-source phase

•

Nominal frequency

•

Frequency range

Physical Requirements

1-3

•

Steady-state current

•

Power consumption

When you are ready to use the above information, turn to Chapter 2 and
find the electrical requirements for your system.
The power source should be able to handle the original system and allow for
system expansion. Digital recommends a dedicated circuit from the power
source for each VAX 4000 system enclosure and a separate dedicated power
circuit for each expander. A dedicated, isolated ground circuit provides
electrical isolation from possible power surges or electrical noise caused by
other electrical equipment. You should not connect any other equipment
such as air conditioners, office copiers, or coffee pots to the same circuit as
your VAX 4000 system or expander.
If you cannot avoid power disturbances, your system will need additional
power-conditioning equipment. For more information, contact your Digital
sales representative. To operate a VAX 4000 system configuration at 240
Vac, obtain the power cable for use in your country. The appendix lists
the power cables used to operate each system at 240 Vac. A power cable
must also be ordered separately to enable the operation of your VAX 4000
system configuration. All orders must have selected the proper power cable
to accompany your VAX 4000 system.

Each VAX 4000 Model 200 and VAX 4000 Model 300 system shipped within
North America includes a 120-Vac power cable.
If your system will be shipped outside North America, or if you require a
240-Vac cable, you must order power cable(s) separately. See Appendix A
for a list of the countries and their associated power cables.

1.3.4 Acoustics
Computer systems generate noise. Higher than acceptable noise levels can
adversely affect a work environment. Digital recommends placing the VAX
4000 systems and the B400X, R400X, B213F, and R215F expanders in an
open office environment.
