VAX 6000: Installing Model 200/300/400 Processors

This document, titled "VAX 6000: Installing Model 200/300/400 Processors," is a technical manual for Digital customer service engineers and self-maintenance customers. Its purpose is to guide users through installing new or replacement processors in previously installed VAX 6000 systems (Models 200, 300, and 400).

The manual covers two primary types of upgrades:

1. Upgrading Within a Model: Adding additional processor modules to an existing VAX 6000 system.
2. Upgrading to Another Model: Replacing processors to convert a VAX 6000 system from a lower model to a higher one, or to convert a VAXserver to a timeshare system.

Key areas covered include:

• An overview of the VAX 6000 series architecture and the different upgrade paths.
• Detailed procedures for recording and setting EEPROM parameters, installing new processors, and managing necessary software upgrades.
• A comprehensive system verification process after an upgrade, which includes performing self-tests, applying ROM patches, running multiprocessor and vector instruction diagnostics, saving system parameters, verifying system operation under the operating system, and updating system identification plates.
• Supplementary appendices provide crucial information on proper module handling precautions, XMI card cage configuration rules for processor placement, interpreting self-test console displays and LED indicators for troubleshooting, and instructions for ROM replacement to convert server modules to timeshare modules.
