VAXBI Expander Cabinet Installation Guide

This document is an installation guide providing comprehensive guidelines and procedures for the mechanical and electrical installation of an H9657-E VAXBI expander cabinet onto Digital Equipment Corporation VAXBI-based systems.

It begins with an introduction outlining the document's scope, listing relevant maintenance documents, and detailing the VAXBI expander cabinet's specifications, including domestic and non-domestic voltage variations, power input boxes (H405-A/B), and six VAXBI option slots. A significant portion of the introduction is dedicated to crucial electrostatic discharge (ESD), safety, and power precautions, emphasizing the need for qualified personnel, proper system shutdown procedures, and warnings about high voltage. It also provides physical dimensions, environmental limits (temperature, humidity, shock, vibration), and detailed electrical requirements, including AC power specifications, connector types, and feed line capacity/circuit breaker size, stressing the importance of a dedicated three-phase Wye power source.

The guide then moves into unpacking and inspecting the cabinet, detailing how to check for external and concealed damage, verify shipment contents, and safely remove the cabinet from its shipping skid using ramps and requiring at least two people due to its weight.

The core of the document covers installation procedures, starting with pre-installation checks and the essential steps to safely bring down the VAX system. It outlines cabinet preparation, including positioning the VAXBI cabinet and opening system end panels, top covers, and bezels. Specific instructions are provided for mounting the VAXBI cabinet to various VAX series systems (6XXX, 8XXX, 92XX, 94XX), along with guidance on checking RF seals. Further sections detail the installation of VAXBI bus cables, including various connection configurations and required extension cables. System configuration is covered through explanations of the System Logic Module (SLM) and Interconnect Logic Module (ILM) switches and indicators, crucial for power-up sequencing and status monitoring. Finally, it describes the steps for closing up the system, applying cabinet power, and bringing the system back online, including initializing the OS and installing diagnostic software.

Appendices list major Field Replaceable Units (FRUs) by part number and description, and provide detailed point-to-point connection information for integrating the VAXBI expander cabinet with different VAX kernel systems.
