VAX 6000: Installing Model 600 Processors

This document, "VAX 6000: Installing Model 600 Processors" (Order Number EK–660EA-UP-001), is a manual for Digital customer service engineers and self-maintenance customers. It provides detailed instructions for installing Model 600 (KA66A) processor modules in a VAX 6000 system.

The manual covers:

1. Introduction and Upgrade Paths: Explains the major upgrade paths, focusing on the system's +3.3V power supply requirements for the KA66A processor, and guiding the user on whether power upgrades (like the H9657-CX or H9657-CU kits) are needed.
2. Preparation for Installation: Steps to perform before physical installation, including recording system parameters, shutting down the system, removing old modules, and procedures for returning old processors. It also notes the required operating system version (VMS 5.5 or later).
3. Power System Upgrades (Conditional): Instructions for systems requiring +3.3V power, such as removing an inhibit cable in Model 300/400 systems or installing an H9657-CX Kit (which includes a T2019 power regulator module and bus bar) for systems without +3.3V power.
4. KA66A Processor Installation: Detailed steps for inserting the new KA66A processor modules into the XMI card cage, including anti-static precautions.
5. System Verification: Procedures to ensure the upgraded system operates correctly, which involves powering up, examining self-test displays, setting and saving system parameters (like the serial number), applying current ROM and PCS patches using the EVUCA program, verifying the system under the operating system (e.g., using UETP for VMS), and updating the system number plate.

Appendices provide general configuration rules for VAX 6000 Model 600 systems and descriptions of KA66A LEDs for troubleshooting.
