VAXft Systems Model 810 Service Information

This document, titled "VAXft Systems Model 810 Service Information" (Order Number: EK-VXFTA-SI.A01), published in June 1993 by Digital Equipment Corporation, is a technical manual intended for trained personnel responsible for maintaining VAXft Model 810 systems.

The manual provides comprehensive information and procedures for hardware service and maintenance. Key areas covered include:

• System Component Descriptions: Detailed overviews of the CPU and expansion cabinets, zone control panels, power modules, and power distribution boxes.
• Console Operations: Instructions on interacting with the system via the console, including different operating modes (Program I/O, Console I/O) and a comprehensive list of console commands for system control, bootstrapping, diagnostics, and data manipulation.
• System Maintenance: Strategies for effective maintenance, general troubleshooting procedures, interpretation of module fault LEDs, power system overviews and maintenance, and analysis of device status and fault indicators for various peripherals (disk drives, tape drives). It also details the use and descriptions of ROM-Based Diagnostics (RBDs).
• Error Handling and Analysis: A thorough explanation of the Error Handling Services (EHS), including error isolation and handling, classification of error types (e.g., CPU/MEM faults, memory errors, cable failures, power failures), and how the system deconfigures faulty Field Replaceable Units (FRUs). It also covers OpenVMS error log analysis, module NVRAM status, and firmware interfaces.
• FRU (Field Replaceable Unit) Removal and Replacement Procedures: Step-by-step guides for safely removing and replacing a wide range of hardware components, distinguishing between "cold swaps" (requiring zone shutdown) and "warm swaps" (without system interruption). This includes procedures for CPU, ATM, SIMM, MMB, fan, power supply, cross-link, console extender, DSSI extender, CAMP, DIM, EIM modules, various disk and tape drives, and power distribution boxes.
• Integrated Storage Elements (ISE) Management: Procedures for loading and using the DUP driver, configuring ISEs using the server setup switch, assigning DSSI unit numbers, and performing "warm swaps" for ISE installation and replacement in a running system.
• Miscellaneous System Information: Appendices provide reference data such as processor and console halt codes, error register descriptions, I/O physical address space, and system control block details.
