AlphaServer 4000/4100 System Drawer Upgrades

This document, "AlphaServer 4000/4100 System Drawer Upgrades," is a quick reference manual for field service personnel. It provides comprehensive instructions for upgrading AlphaServer 4000/4100 family systems, covering both cabinet and pedestal configurations, by exchanging the system drawers.

The manual is structured into three main chapters:

1. Overview: Details pre-installation steps, including recording system information and saving essential data (like environment variables) to a diskette. It also lists the required tools (Phillips and flathead screwdrivers).
2. Installing the Upgrade: Provides step-by-step procedures for removing the old system drawer (for both cabinet and pedestal types), transferring components such as I/O option cards, CPU cards, and memory cards to the new system drawer, and then installing the new drawer. Warnings regarding the system drawer's weight (45 kg/100 lbs) and the need for two people for certain tasks are highlighted.
3. Verification: Covers post-installation steps, specifically restoring the system information from the previously saved diskette and updating the system firmware using the Loadable Firmware Update (LFU) utility.
