General Requirements
Read this chapter for general requirements. Then refer to Chapter 2 for the
specific requirements of your system. To ensure smooth installation and operation
of the system, your site must meet the requirements in both chapters before the
arrival of your system shipment.
Note
Digital recommends that a Digital service representative install your
system.

Digital provides a site preparation service. If you want Digital to prepare your
site, contact your Digital service or sales representative.

1.1 System and Expander Enclosure Designations
The following table lists the enclosures in which the systems and expanders are
shipped. For simplicity, enclosure designations are used throughout this manual
rather than the system or expander name. There are other supported expander
cabs that are not mentioned here. Refer to the documentation that comes with
those units.

The physical requirements for your system are determined by its dimensions
before and after the shipping carton is removed, space for doors to swing open,
space for peripheral equipment such as printers and terminals, allowances for
adequate airflow around the system, and the noise emission level of the system.

1.2 Space Requirements
Before unpacking your equipment, make sure you have enough space to remove
the system from its shipping carton. You need 1.5 to 1.8 meters (5 to 6 feet) to
the side of the carton to allow room for rolling the system off its shipping ramp.
The BA42 needs less space. Also make sure you leave enough space around the
system so it can be serviced. The dimensions of cartons and enclosures are shown
in Chapter 2.
You must leave at least 1 meter (39 inches) of clearance at the front of your
system for opening the doors and to access system controls. You must also leave
at least 5 centimeters (2 inches) of clearance at the sides and rear for airflow.
Since the base of the enclosure is 5 centimeters (2 inches) 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.
In addition to the space required for your system, you should ensure that you
have enough space for any expanders, terminals, printers, mass storage media,
printer paper, and other necessary supplies.

1–2 General Requirements

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 be in place and labeled before
your system is installed.

When planning cable routing for multiterminal equipment, you should consider
factors such as safety, convenience, future expansion, and cost. And there are
other factors to consider when cabling a multiterminal system on more than one
floor in the same building or in more than one building. Digital offers several
cable types for such applications, and Digital service personnel are available
to help you plan your installation. Your sales representative can provide more
information.

1.3 Operating Environment
Your system is affected by the discharge of static electricity, temperature changes,
and humidity. Those conditions can affect the operation and overall dependability
of your system.

1.3.1 Static Electricity
Static electricity is a common problem. 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 minimize static buildup, follow these guidelines.
•

Maintain a relative humidity of at least 40 percent.

•

Locate your system away from busy office corridors.

•

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

•

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

General Requirements 1–3

1.3.2 Temperature and Humidity Ranges
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 your system 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.
Mass storage media and other computer supplies, including paper, should be kept
at the same temperature and humidity as that of the computer area.
When calculating the operating temperature in your 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.

1.4 Electrical Requirements
In determining the electrical requirements of your system or expander, consider
the following.
•

Voltage range

•

Power-source phase

•

Nominal frequency

•

Frequency range

•

Steady-state current

•

Power consumption

When you are ready to use that information, turn to Chapter 2 and find the
electrical requirements for your system.

1.4.1 Power Source
The power source should handle your system and allow for system expansion.
Digital recommends a dedicated circuit from the power source for each system
and a separate dedicated circuit for each expander. A dedicated ground circuit
provides electrical isolation from 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 system or
expander.

1–4 General Requirements

If you cannot avoid power disturbances, your system will need additional powerconditioning equipment. For more information, contact your Digital sales
representative.
Each 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 the power cable(s) separately. See the appendix for a list of
the countries and their associated power cables.

1.4.2 Grounding
If you will be installing two or more enclosures (system or expander) and if they
will be connected by a common DSSI bus, improper grounding can result in
voltage potentials, called ground offset voltages, between the enclosures. And if
those voltages exceed certain limits, data transmission across the DSSI bus can
be disrupted and your system can experience performance degradation or data
corruption.
To prevent system performance degradation or data corruption caused by
excessive ground offset voltages:
1. Have a qualified electrician check to make sure your site power distribution
system meets all local electrical codes.
2. Also have that electrician inspect your entire site power distribution system
to make sure it does not have any of these faults.
a. Outlets do not have power ground connections.
b. Grounding prong missing from computer equipment power cables.
c.

Power outlet neutral connections are actually ground connections.

d. Grounds for the power outlets are not connected to the same power
distribution panel.
e.

Devices that are not UL or IEC approved are connected to the same
circuit breaker as the computer equipment.

If all the requirements in steps 1 and 2 are met, the ground offset voltages should
be within acceptable limits for DSSI operation. If any of those requirements
cannot be met, after your system is installed and turned on you should check the
ground offset voltages as described in the system Installation manual.
Note
To ensure proper grounding, you should check the ground offset voltages
even if all the requirements in steps 1 and 2 are met.

General Requirements 1–5

1.5 Acoustics
Computer systems generate noise. Higher than acceptable noise levels can
adversely affect your work environment. Digital recommends placing your system
and B400X, R400X, B213F expanders in an open office environment.

1.6 When Your Shipment Arrives
When your system arrives, you should inspect it with a Digital service
representative to ensure that the system and all ordered options arrived
undamaged.
When you are ready to begin installation, find the Customer Hardware
Information Kit (in the system shipping carton) and begin using the Installation
manual and Installation Checklist to install your system.
