RA90/RA92/H9643 Installation Guide

This document, the RA90/RA92/H9643 Cabinet Installation Guide, provides comprehensive instructions for users and Digital Customer Services engineers on installing RA90/RA92 disk drives into an H9643 cabinet system. While it covers aspects of the full cabinet system installation, its primary focus is on the process of adding RA90/RA92 add-on disk drives to existing H9643 cabinets.

Key areas covered in the guide include:

• Product Overview: Descriptions and detailed specifications (physical, environmental, electrical) for the RA90/RA92 disk drives and the H9643 cabinet, which can house 1 to 6 drives.
• Preparation: Instructions for mandatory thermal stabilization of the equipment, unpacking the RA90/RA92 add-on disk drive (including warnings against improper lifting), and procedures for repackaging equipment for storage or shipment.
• Installation Steps: Guidance on site preparation, required hardware, and the specific sequence for adding disk drives to maintain cabinet stability (e.g., center level first, then bottom level).
• Cabinet Access: Procedures for removing and replacing various cabinet components like front bezels, operator control panels (OCPs), rear access panels, top covers, and kick plates to facilitate drive installation.
• Disk Drive Placement: Detailed steps for physically placing the add-on disk drive into the cabinet, emphasizing the use of a lifting device due to the drive's weight, and securing it with appropriate brackets and screws.
• Cabling: Instructions for routing and connecting internal Standard Disk Interface (SDI) cables and power cords within the cabinet.
• Applying Power: Explanations of power connector configurations, operation of the 874-series power controller (including its circuit breaker and remote/off/local switch), setting the RA90/RA92 voltage selector switch, and the final power-up sequence for the entire cabinet system.

The guide stresses critical precautions such as adhering to thermal stabilization before opening moisture barrier bags and taking electrostatic discharge (ESD) measures. It also directs users to a separate H9643 Cabinet System User Guide for detailed unpacking and de-skidding procedures of the full cabinet system.
