AlphaServer ES40 Model 1 to Model 2 Upgrade

This document is an upgrade guide for the Compaq AlphaServer ES40, specifically detailing the process to upgrade a Model 1 system to a Model 2.

Intended for service providers and self-maintenance customers, its primary purpose is to increase the system's memory and I/O capacity. The upgrade involves the replacement of existing 4-slot memory motherboards (MMBs) with 8-slot MMBs and the 6-slot PCI backplane with a 10-slot PCI backplane.

The guide covers essential steps including:

• Preparation: System shutdown, power removal, and safety warnings.
• Physical Upgrade: Instructions for removing enclosure panels, accessing rackmount systems, removing chassis covers, and the step-by-step replacement of the Memory Motherboards (MMBs) and the PCI Backplane.
• Verification: Procedures to confirm the successful upgrade using system configuration commands (e.g., show config for Tru64 UNIX/OpenVMS or checking AlphaBIOS setup for Windows NT).
