This document, the "VAX 7000 Pocket Service Guide," is a quick reference manual designed for Digital service engineers. It provides essential technical information and procedures for VAX 7000 systems.
Key contents include:
- System Registers: Detailed lists and illustrations of various hardware registers (KA7AA, MS7AA, I/O Port, DWLMA, Gbus), crucial for understanding system state and low-level operations.
- Addressing: Information on address space layouts (virtual, physical), and specific addresses for LSB, XMI, and VAXBI components and devices.
- Console Operations: A comprehensive guide to console commands, their syntax, environment variables, device naming conventions, and examples for tasks like booting, configuration display, and device examination.
- Diagnostics: Instructions and examples for running diagnostic tests on adapters, device controllers, and other system components, including DUP-based and remote XMI adapter diagnostics.
- Field-Replaceable Units (FRU) Locations: Detailed identification and location of various FRUs within the platform cabinet, XMI plug-in unit, disk plug-in unit, and battery plug-in unit, along with platform cabling.
- Controls and Indicators: Descriptions of the meaning of lights, switches, and other indicators on key system components such as the control panel, processor module, power regulators, and I/O modules.
- ROM Restoration: Procedures for recovering from corrupted EEPROMs and updating corrupted firmware on adapters and CPUs.
- System Errors: Explanations of machine check frames and various parse trees (hard error, soft error, I/O port, DWLMA) for diagnosing system failures.
