SW300-Series Raid Enclosures Installation and User Guide

This document is the Installation and User's Guide for the Digital StorageWorks SW300-series RAID Enclosure. Published by Digital Equipment Corporation, it serves as a comprehensive manual for customers and service personnel involved in the installation, configuration, operation, and maintenance of this redundant array of independent disks (RAID) system.

The guide covers:

• An introduction to the SW300 enclosure, detailing its physical characteristics, specifications, and major components (including AC power entry controllers, a high-availability fault bus, environmental monitor units (EMUs), HS array controllers, dual-speed blowers, power supply SBBs, and storage device SBBs), as well as its SCSI bus architecture.
• Unpacking and installation instructions, guiding users through site preparation, unboxing, placing the enclosure, connecting power cords, and applying initial power.
• Configuration rules and restrictions, outlining supported system and power configurations, SCSI bus assignments, and recommended component loading sequences.
• Error analysis and fault isolation, explaining how to interpret various light-emitting diodes (LEDs) on the front panel, EMUs, HS array controllers, power supply SBBs, and storage device SBBs to diagnose system faults.
• Removal and installation procedures for all major field-replaceable units (FRUs), such as power supply SBBs, storage device SBBs (including warm swap procedures), environmental monitor units, controllers, dual-speed blowers, and AC power entry controllers.
