VAXserver/VAX 4000-Series System Conversion Guide

This document, the "VAXserver/VAX 4000-series System Conversion Guide" from October 1992, provides detailed instructions for upgrading various Digital Equipment Corporation (DEC) VAXserver and MicroVAX systems to newer VAX 4000-series models.

The guide is intended for Digital Services personnel and licensed self-maintenance customers. It outlines specific conversion procedures for different original systems, including:

• VAXserver/MicroVAX 3300/3400, 3500/3800, and 3600/3900 systems to VAXserver/VAX 4000-200.
• VAXserver 4000-200 systems to VAX 4000-200 (implying a change in system role/model).
• VAX/VAXserver 4000-300, -400, and -500 systems to higher-end VAX/VAXserver 4000-300, -400, -500, and -600 models.

Each conversion chapter details a consistent set of steps:

1. Preparation: Ensuring customer system software backup, running diagnostics, and unpacking the conversion kit while adhering to antistatic precautions.
2. Hardware Installation: Removing old CPU modules and potentially memory, installing new CPU modules (e.g., KA660, KA67x series) and compatible memory, and reconnecting all associated cables, I/O panels, and internal components like DSSI cables. For some upgrades, replacing the BA440 backplane is also covered.
3. Post-Installation: Attaching new system labels and medallions, running comprehensive system diagnostics, and obtaining customer verification that the system boots and operates correctly.

A crucial aspect emphasized is the mandatory return of old CPU modules to Digital Equipment Corporation, with detailed forms and procedures for this process provided in Appendix A. The document also specifies system requirements, such as minimum VMS software versions and backplane revisions, necessary for supporting the upgraded CPUs. Throughout the guide, strong cautions are given regarding static discharge and safe handling of components due to their weight.
