DEC FDDIcontroller/Q-bus Installation

This document, "DEC FDDIcontroller/Q-bus Installation," published in April 1993, provides a comprehensive guide for qualified service personnel to configure, install, and verify the operation of the DEC FDDIcontroller/Q-bus within Q-bus-based MicroVAX and VAX systems, and how to connect it to an FDDI network.

Key areas covered include:

• Introduction to the Controller: An overview of the FDDIcontroller/Q-bus, its available models (Single Attachment Station - SAS, and Dual Attachment Station - DAS), and identification of its components.
• System Configuration: Detailed steps on adding the controller to the host system's configuration, involving verifying system software prerequisites (OpenVMS VAX), determining the current system configuration, and setting the Controller Status Register (CSR) address switches.
• Physical Installation: Instructions for preparing the system, physically installing the controller, installing gap fillers for EMI compliance, connecting and properly dressing FDDI cables, and installing the necessary device drivers.
• Verification: Procedures for verifying the controller's hardware installation and the FDDI communications connection, often through LED indicators.
• Troubleshooting: Guidelines for diagnosing and resolving issues, including running self-tests, interpreting LED displays for different states, and general hardware problem-solving.
• Appendices: Additional technical information on MicroVAX Diagnostic Monitor (MDM) diagnostics, FDDI connector keying, optical bypass information, and specifications (power and environmental requirements), as well as a list of related documentation.

The document also highlights important safety warnings, particularly concerning static electricity and potential laser light hazards from fiber optic equipment.
