MicroVAX 3100 Platform CPU Reference Information

This document, "MicroVAX 3100 Platform CPU Reference Information," is a technical manual published by Digital Equipment Corporation in November 1991. It provides comprehensive reference information for maintaining systems that use the KA45 or KA47 CPU modules.

Intended for Digital Services personnel and self-maintenance customers, the manual is structured into six chapters, a glossary, and an index, covering:

• Console Commands: Detailed descriptions of commands available in console mode, including operations like booting, depositing and examining data, finding memory segments, halting, system initialization, login, setting various system parameters (e.g., boot flags, diagnostic environment, halt actions, network listener, security password, radix, SCSI ID, remote trigger), and displaying system information.
• Console Codes and Messages: Explanations of codes and messages generated by the console program during system operation.
• Power-Up Test and Self-Test Error Codes and Messages: Extensive lists and explanations of error codes and messages produced by the firmware's power-up and self-tests for various components (NVR, DZ, CACHE, MEM, FPU, IT, SYS, NI, SCSI, COMM, ASYNC tests), including additional diagnostic information formats.
• Utilities Error Codes and Messages: Details on error codes and messages generated by specific system utilities, such as SCSI and COMM utilities.
• System Exerciser Error Codes and Messages: Information on error messages reported by system exerciser tests (DZ, NI, SCSI, COMM, ASYNC), which are more thorough diagnostic tests.
• LED Display Codes: Guidance on interpreting the diagnostic codes displayed on the LED lights of the KA45 and KA47 CPU modules to indicate system status and test failures.

The manual aims to provide all necessary information for troubleshooting and maintaining MicroVAX 3100 systems at a detailed hardware and console level.
