Preface
Intended Audience
This manual is written for the system manager or system operator who
has training in systems management and is running a DEC 7000 AXP system or a 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 four chapters and three appendixes, as follows:
• Chapter 1, DEC 7000 AXP System and VAX 7000 Systems, and
Chapter 2, System Components, give a basic introduction to your
system and its parts.
• Chapter 3, Controls and Indicators, describes how the system pre-
sents information and how you use the switches.
• Chapter 4, Booting, explains how you turn on the system and get it
running.
• Appendix A, Console Commands, lists the console commands with
a brief explanation of each command.
• Appendix B, Boot Options, lists options used with the boot com-
mand to control various phases of booting.
• Appendix C, Updating Firmware, explains how to run the Loadable
Firmware Update (LFU) Utility.
• A Glossary and Index provide additional reference support.

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
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:

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 section shows a sample boot of OpenVMS Alpha AX
from the RRD42 CD drive for DEC 7000 systems. The firs
step is issuing the show device command to determine th
location of the RRD42.

DEC 7000 AXP System and
VAX 7000 System
The DEC 7000 AXP system and VAX 7000 systems are designed for
growth offering configuration flexibility, an outstanding I/O subsystem,
and expansion capability in a single or multicabinet environment. The
DEC 7000 system or VAX 7000 system can support many users in a timesharing environment. These systems do the following:
• Support the full range of system applications of OpenVMS Alpha AXP
or OSF/1 for DEC 7000 systems and OpenVMS VAX for VAX 7000 systems
• Allow for expansion of processors, memory, and I/O
• Use a high-speed system interconnect bus (LSB bus), which has an ef-
fective bandwidth of 640 Mbytes/sec.
• Support up to 3.5 Gbytes of physical memory
• Provide optional self-contained uninterruptible power system (UPS)
capability that supports the system in case of power failure
• Perform automatic self-test on power-up, reset, reboot, or system initialization
• Operate as a standalone system, a member of a cluster, or as a boot
node of a local area cluster
The chapter describes the system package and introduces the location of
components in the cabinet—both front and rear views. Sections include:
• System Characteristics
• System Architecture
• Sample System
• System Front View
• System Rear View

1-4 DEC 7000 AXP System and VAX 7000 System
The LSB bus is a synchronous 128-bit system bus that interconnects the
processors, memory modules, and the I/O port (IOP) module. The IOP
module connects the LSB bus to I/O buses through separate I/O adapter
modules.
The LSB bus uses the concept of a node. The LSB bus has three types of
nodes: processors, memories, and an I/O port controller.
A processor node is a single-module scalar processor. It consists of a
CPU chip, the LSB bus interface, cache, and support logic. DEC 7000 systems use the KN7AA processor, and VAX 7000 systems use the KA7AA
processor.
In a multiprocessing system, one processor becomes the boot processor during power-up, and that boot processor loads the operating system and handles communication with the operator console. The other processors become secondary processors and receive system information from the boot
processor.
A memory node is one memory module. Memory is a global resource
equally accessible by all processors on the LSB. Memory modules can have
64, 128, 256, or 512 Mbytes of memory with ECC and associated control
logic. The memories are automatically interleaved when the system is configured with multiple memory banks. The system supports up to seven
memory modules.
The I/O port controller is the IOP module, which serves as the interface
between the LSB bus and up to four I/O buses. In Figure 1-2 the DWLMA
module is the I/O bus adapter module that connects the XMI I/O channel
to the IOP module.
The XMI I/O channel also has I/O bus adapter modules that connect to
various interconnects such as CI, DSSI (for VAX 7000 systems only),
SDI/STI, SCSI (for DEC 7000 systems only), FDDI, and Ethernet.

1.3 Sample System
Figure 1-3 shows a sample system. The system includes a console
terminal and printer, an accessories kit, and a documentation set,
which includes this manual. The system can have up to two optional expander cabinets, an in-cabinet tape drive, disk drives,
an RRD42 CD drive for DEC 7000 systems, or a battery plug-in unit
(PIU).

Your Digital customer service engineer has installed your system and
verified that it is running properly. Before you turn on the system, familiarize yourself with its components:
• The system cabinet houses the LSB card cage, power system, cooling
system, and the control panel with status indicators. Optional hardware includes an in-cabinet tape drive, in-cabinet CD-ROM, disk plugin units (PIUs), battery PIUs, and I/O PIUs.
• The console load device is used for installing operating systems and
software.
• The console terminal is used for booting and for system management
operations.
NOTE: The console terminal is not to be used as the primary user interface
for text editing.
• The console printer provides a hardcopy record of system operations.
• Optional PIUs include the XMI PIU, DSSI PIU (for VAX 7000 sys-
tems), and the battery PIU. These plug-in units are installed in the
system or expander cabinets to provide space for I/O, disk, and battery
options.
• Optional expander cabinets provide additional space for I/O de-
vices, disk drives, and a battery option.
• A system documentation kit

2.1 Console Load Devices
The RRD42 compact disk (CD) drive is the in-cabinet console load
device for DEC 7000 systems. The InfoServer is the console load
device for VAX 7000 systems. During system installation the console load device is used to boot standalone backup. It is also used
to boot the Loadable Firmware Update (LFU) Utility.

The RRD42 compact disk (CD) drive is the console load device for
DEC 7000 systems. It is installed in the system cabinet and used
to access software and on-line documentation. The KZMSA
adapter is installed in the XMI card cage and provides access to
the RRD42.
The InfoServer is the console load device for VAX 7000 systems. I
is an Ethernet-based compact disk (CD) drive, which is part of a
local area network. The InfoServer is used to access CD-ROMs for
software installation and for on-line documentation on VAX 7000
systems.
The DEMNA and DEMFA adapters are interfaces that allow access to the InfoServer. These adapters are modules installed in th
XMI card cage. A bulkhead connector, which connects to the Ethernet, mounts on the rear of the XMI PIU bulkhead panel. Figure
2-1 shows how the DEMFA provides access to the FDDI (Fiber
