AlphaServer 1000 CPU Upgrade Information

This document, "AlphaServer 1000 CPU Upgrade Information," provides a step-by-step guide for customers and Digital service representatives on how to upgrade the CPU module of an AlphaServer 1000 system.

The upgrade process involves:

1. Preparation: Checking the existing firmware version (requiring 3.0-15 SRM or 4.26 ARC or higher), properly shutting down the operating system, and ensuring all external options and the system unit are powered off.
2. Hardware Replacement: Detailed instructions are provided for safely removing the top cover and side panels, extracting the existing CPU card, installing the new CPU card into its designated slot, and then replacing the covers. Crucial safety warnings are highlighted, including the use of antistatic wrist straps, ensuring the system is off before opening, and waiting for components to cool down.
3. Firmware Update: After the physical CPU replacement, the document outlines procedures to update the system firmware (residing on FlashROM chips). This can be done via a CD-ROM drive, a network, or a diskette drive, with specific instructions provided for OpenVMS/Digital UNIX and Windows NT systems.
4. Completion and Verification: The final steps include verifying the successful installation by checking the operator control panel for the new CPU speed ("Model 4/xxx"), recording the upgrade number, and instructions for returning the old CPU to Digital Equipment Corporation.

The guide emphasizes important safety precautions and provides conventions for understanding command-line instructions.
