DEC 3000 Model 400 AXP Owner's Guide

This document is an Owner's Guide for the DEC 3000 Model 400/400S AXP system, published by Digital Equipment Corporation in March 1993. It serves as a comprehensive manual for users, covering installation, operation, maintenance, and troubleshooting.

Key areas covered include:

• System Overview: Describes the DEC 3000 Model 400 (workstation) and 400S (server) configurations, highlighting features like the Alpha AXP architecture, flexible memory, various ports (AUI, 10BASE-T, ISDN, audio), TURBOchannel slots, security features, and supported operating systems (OpenVMS AXP and DEC OSF/1 AXP). It also details graphics and audio capabilities, and available internal/external options.
• Installation: Provides step-by-step instructions for preparing the site (location, ergonomics), unpacking the system (workstation or server), connecting components like monitors, keyboards, mice, power cords, and Ethernet loopback connectors.
• Networking: Explains how to connect the system to different network types (AUI Ethernet, 10BASE-T, ThinWire Ethernet) and verify network connections.
• System Startup and Shutdown: Guides users through turning on and off the system and its peripherals, reviewing startup displays, and handling factory-installed or loading new operating system software.
• Maintenance: Offers advice on caring for the system unit, keyboard, monitor, and mouse, including cleaning procedures and handling accidental spills.
• Advanced Operations: Details how to use console commands (boot, continue, halt, help, set/setenv, show/printenv, test), change environment variables (e.g., default boot device, startup action, diagnostic mode, keyboard language), and utilize the password security feature (setting, enabling, changing, disabling, erasing).
• Troubleshooting: Provides methods for identifying and resolving common system problems, including startup issues (power indicator, no display, errors, boot failures), display problems (cursor, distortion, no display), daily operations issues (missing pointer, keyboard not working), SCSI device problems (disk drives, diskettes, software booting), and network problems.
• Diagnostics: Outlines procedures for running diagnostic tests on system components, recording diagnostic display light patterns, and reporting problems to Digital Services with contact information.
• Appendices: Includes hardware specifications (dimensions, electrical, environmental), port pin-outs for various connectors, and a list of associated documentation.

The guide is structured into four parts: Basic Operations, Advanced Operations, Handling Problems, and Appendices, with task difficulty indicated by symbols.
