MicroVax/VAXserver 3000-Series to VAX 4000 Model 200

This document is a Conversion Guide (published February 1991) by Digital Equipment Corporation, detailing the process for upgrading MicroVAX 3300/3400 systems to VAX 4000 Model 200 systems, and VAXserver 3300/3400 systems to VAXserver 4000-200 systems.

It is intended for Digital Customer Services personnel and licensed self-maintenance customers.

Key information and procedures covered include:

• Conversion Process Overview: A step-by-step summary of the conversion, including backing up software, running diagnostics, unpacking the kit, removing old components (front panel, CPU, I/O panels), installing the new KA660-AA/BA CPU module, and reassembling the system with new labels and medallions.
• Critical Memory Upgrade: It explicitly warns that existing MS650-AA memory modules are incompatible with the new CPU and must be replaced with MS650-BA or MS650-BB memory.
• Customer and Digital Responsibilities: Outlines that customers are responsible for software backup and, if not self-maintenance qualified, for contacting Digital for conversion scheduling. Digital Customer Services representatives are responsible for completing the installation and the necessary return forms.
• Module Return Procedure: A significant portion is dedicated to the mandatory return of the old CPU module to Digital. It explains that specific forms (Customer Services Worksheet, Installation Receipt, Return Material Checklist) must be completed and signed by both the customer and the representative, and that failure to return the module will result in a penalty charge.
• Safety Precautions: Emphasizes the use of antistatic wrist straps and mats when handling modules.

The guide also lists the specific conversion kits, their contents, and associated VMS licenses, along with contact information for Customer Administrative Services (CAS) district offices.
