DEC 2000 Model 300 AXP Upgrade Information

This document, titled "DEC 2000 Model 300 AXP Upgrade Information" and published by Digital Equipment Corporation in December 1993, serves as a technical guide for customers and Digital Services personnel.

Its primary purpose is to provide step-by-step instructions for removing specific hardware options from various older DEC systems so they can be reused with a new DEC 2000 Model 300 AXP system.

The document details procedures for:

• Identifying compatible options: These include various SCSI disk drives (e.g., RZ24L, RZ25, RZ26), CD-ROMs (RRD42), tape drives (TLZ06, TZK10), a color monitor (VRC16-HA), and expansion boxes (SZ12/RZ5x, BA353, BA350).
• Preparing existing systems: This involves shutting down the system, disconnecting cables, and carefully removing components like system covers, front drive panels, removable media drives, fixed disk drives, EMI shields, and communication options.
• Preparing removed components: Crucially, users are instructed to verify and potentially adjust SCSI IDs on the drives, and to install new mounting brackets (provided in the upgrade kit) onto the removed drives.
• Completing the upgrade: The document frequently refers to other manuals (e.g., "DECpc AXP 150 and DEC 2000 Model 300 AXP Customer Technical Information" and "User Information") for the final steps of installing these prepared components into the new DEC 2000 AXP system.
• Returning old equipment: Users are instructed to return their old DEC system and any non-upgradeable devices to Digital, and to update their service contracts.

It covers specific upgrade paths from systems such as DECsystem 5000 (Model 133/150), DECstation 5000 (Model 20/25/33/50), DECsystem 3100, DECsystem 5100, DECsystem 5500, MicroVAX 3100 (Model 30, 40/80/90), MicroVAX 3300/3400, and VAX 4000 (Model 100). Notably, it specifies that no internal or external options can be upgraded from VAX 11/7xx, MicroVAX 2000, MicroVAX I and II, or DECsystem 5400.

The document also emphasizes the importance of using antistatic precautions to prevent damage to components during the upgrade process.
