SF400 DECarray Installation Guide

This document is the SF400 DECarray Installation Guide, intended for qualified Digital Services personnel. It provides comprehensive steps to install and configure the SF400 DECarray cabinet, along with its SF-series storage enclosures (SF3x and SF7x) and TF-series magazine tape Integrated Storage Elements (ISEs).

The guide covers:

1. Overview and Specifications: Describes the SF400 DECarray as a storage cabinet designed to hold up to 10 disk or tape ISEs, its modular design, optional dual AC power, and DSSI interface capabilities. It provides detailed specifications including dimensions, weight, electrical requirements, and environmental limits. It also introduces the SF3x (up to 12 half-height 3.5-inch ISEs) and SF7x (up to 4 full-height 5.25-inch ISEs) storage enclosures, noting their configurable through-bus or split-bus modes.
2. Site Preparation: Outlines crucial environmental and power requirements for installation, emphasizing the need for three-phase AC power, adequate clearance, floor weight capacity, and proper grounding for DSSI connections.
3. Physical Cabinet Installation: Details the process of unpacking the DECarray cabinet from its shipping pallet (requiring multiple people), careful placement, leveling, trim kit installation, and initial inspection, including considerations for thermal stabilization.
4. Cabinet Configuration, Cabling, and Labeling: Explains how to set up the DECarray for single, dual, or triple host configurations. It provides instructions for routing and connecting DSSI cables directly to storage devices, setting unique DSSI node IDs, and labeling all components and cables using system configuration sheets.
5. Component-Specific Installation: Provides detailed step-by-step procedures for installing magazine tape ISEs (Chapter 5), SF7x storage enclosures (Chapter 6), and SF3x storage enclosures (Chapter 7). These sections cover unpacking, chassis rail installation, mounting the units, power cord connections, configuring internal settings (like split-bus mode and DSSI ID switches), and internal cabling.
6. Powering Up and Verification: Guides users through applying power to the cabinet and individual components, observing operator control panel (OCP) indicators, running power-on self-tests (POST), and performing final verification of the DSSI subsystem and device operation with the host system.
7. Troubleshooting: Includes a section with a detailed chart for diagnosing and resolving common installation problems related to storage enclosures and tape ISEs, covering symptoms, probable causes, and corrective actions (e.g., conflicting DSSI IDs, power issues, faulty cables). It also provides procedures for removing and bringing disk ISEs online.

The document consistently emphasizes safety precautions, adherence to electrostatic discharge (ESD) procedures, and the necessity of orderly system shutdowns when performing any installation or maintenance tasks.
