DECsystem 5900 StorageServer 100 Installation Guide

This document is the "DECsystem 5900 StorageServer 100 Installation Guide," published by Digital Equipment Corporation in June 1992. It is intended for Digital service personnel and qualified self-maintenance customers.

The guide provides step-by-step instructions for installing the StorageServer 100 on a DECsystem 5900. The StorageServer 100 is described as an economical optical disk autochanger for accessing large amounts of offline information. It features:

• An autochanger mechanism
• Two 5.25-inch multifunctional optical disk drives (rewritable/write-once)
• A mail slot for disk insertion/removal
• Storage slots for 32 optical disks, totaling 20.8 Gbyte capacity
• A Small Computer Systems Interface (SCSI)

The installation process covers:

1. Preparing the DECsystem 5900: Balancing the system and turning off power.
2. Removing and Reinstalling Mass Storage Drawers: Instructions for moving existing mass storage drawers to accommodate the StorageServer 100 in designated slots (slots 1 & 2 for single CPU configurations, or slots 5 & 6 for dual CPU configurations). This section also details removing shipping brackets and re-connecting cables.
3. Assembling and Installing the Rackmount Slide Assembly: Steps for assembling the necessary slide hardware and installing it into the DECsystem 5900 cabinet, including a "dress mid panel" if installing in lower slots.
4. Installing the Rackmounted StorageServer 100: Physically placing the StorageServer 100 onto the slide assembly, attaching SCSI and power cables, and performing diagnostic tests (Power-Up Self-Test and CNFG console command) to verify proper connection and functionality. The document notes that software installation is covered in separate guides.

An addendum is included, providing modifications and updated instructions for certain steps in Chapter 3 and 4, particularly concerning specific hole numbers for slide installation and detailed procedures for setting SCSI IDs for the optical drives and autochanger controller.

Throughout the guide, cautions are provided regarding system balancing, static electricity, and the need for multiple people (two to four, depending on the task) for lifting heavy components.
