Preface
Intended Audience
This manual is written for Digital customer service engineers and customers preparing a site for a DEC 7000 or VAX 7000 system.

Document Structure
This manual uses a structured documentation design. Topics are organized into small sections for efficient on-line and printed reference. Each
topic begins with an abstract. You can quickly gain a comprehensive overview by reading only the abstracts. Next is an illustration or example,
which also provides quick reference. Last in the structure are descriptive
text and syntax definitions.
This manual has one chapter, as follows:
•

Chapter 1, Site Preparation, provides pre-installation requirements and guidelines for DEC 7000 and VAX 7000 systems.

Conventions Used in This Document
Terminology. Unless specified otherwise, the use of "system" refers to
either a DEC 7000 AXP or VAX 7000 system. The DEC 7000 AXP systems
use the Alpha AXP architecture. References in text use DEC 7000 to refer
to DEC 7000 AXP systems.
When a discussion applies to only one system, an icon is used to highlight
that system. Otherwise, the discussion applies to both systems. Thus, the
abstract for a module that applies only to DEC 7000 systems would look
like this:
This section shows a sample boot of OpenVMS Alpha AXP
DEC from the RRD42 CD drive for DEC 7000 systems. The first
7000
step is issuing the show device command to determine the
location of the RRD42.
Book titles. In text, if a book is cited without a product name, that book is
part of the hardware documentation. It is listed in Table 1 along with its
order number.
Icons. The icons shown below are used in illustrations for designating part
placement in the system described. A shaded area in the icon shows the
location of the component or part being discussed.

This chapter provides site planning guidelines, cabinet sizes, space and environmental requirements, and system power requirements.
Sections include:
•

Pre-Installation Checklist

•

Cabinet Sizes

•

•

AC Power Cable and Connectors

Site Preparation 1-1

1.1 Pre-Installation Checklist
Site planning guidelines and tasks are listed below. The tasks can
be checked off when completed before system delivery. To facilitate the installation process, it is recommended that the customer
plan ahead and coordinate the site planning and scheduling details with Digital.
Planning the Site:
Plan the physical layout of the system cabinet, expander cabinets, console terminal, and other system units.
Plan to place all equipment away from heavy traffic centers leaving
enough room for airflow and maintenance.
Obtain cabinet weights and dimensions to check against floor loading
restrictions.
Determine the sizes of circuit breakers and the number of branch circuits required.
Determine number, type, and location of required AC power outlets.
Check the compatibility of different power sources. This must be
checked when multiple types of power distribution transformers, or
power conditioning equipment is used.
Determine system power consumption to calculate the input line power
requirement.
Establish a system grounding scheme for the installation.
Determine environmental cooling requirements.
Check the location and requirements of cabling for communication devices such as Ethernet.

1-2

Site Preparation

Checking the Delivery Route:
Check the height, width, and location of doors and passageways for
adequate clearance.
Check floor loading requirements along passageways.
Check passageway restrictions such as corners, ramps, or obstructions.
Check the size, capacity, and availability of elevators.
Table 1-1 lists the shipping dimensions for the system and expander cabinets. These dimensions include the width of the shipping pallet, the
height of the shipping boxes, and the weight of the packing materials.

The minimum amount of clearance space for the system front is 150 cm (59
in) and rear is 100 cm (39 in), as shown in Figure 1-2. These clearances
are needed for airflow and maintenance.
Airflow
Air is taken in through the top and bottom of the cabinet by a dual wheel
blower. The air is then circulated through the card cages and power regulators. It is vented at the middle of the cabinet front and rear.
NOTE: Inadequate airflow can result in the system shutting down,

power regulators, cabinet control logic (CCL) module, optional
48V batteries, power distribution cables, and signal interconnect
cables.

1.5 AC Power Cable and Receptacles
The AC power cable is 2.8 m (9 ft) in length. It consists of threephase leads (X, Y, and Z) plus neutral (N) and ground (G). AC
power connectors are shown in Figure 1-4.
NOTE: Neutral and ground lines must both be connected from the bulk
three-phase power to complete the Wye configuration. Otherwise,
power components may be damaged. Do not power up the system
until power checks are completed.
