LNV21-SF Controller Installation/Owner's Manual

This document is the Installation/Owner's Manual for the LNV21-SF Controller, identified as EK-V21SF-IN-001 and prepared by Computer Special Systems in November 1988 for Digital Equipment Corporation.

The manual provides comprehensive instructions for configuring, installing, and testing the LNV21-SF Controller within VAXstation 3500 systems. It is primarily intended for Digital Field Service personnel and qualified self-maintenance customers who possess the MicroVAX System Maintenance Kit.

The LNV21-SF Controller consists of:

• A quad-height M8087 Printed Circuit Board (PCB) that provides connections for external devices, specifically a laser printer and a scanner.
• Gap fillers (P/N 70-24505-01) used to ensure FCC compliance and ground continuity when installing modules.
• A loopback cable (P/N 17-02250-01) for diagnostic purposes only.

The manual is structured into three main chapters:

1. Chapter 1: Description provides an overview of the LNV21-SF Controller and the BA213 Micro System Enclosure (which houses the VAXstation's Q22-bus). It details the components of the LNV21-SF option (M8087 module, gap fillers, loopback cable) and outlines the physical, electrical, and environmental specifications of the controller.

2. Chapter 2: Installation offers step-by-step procedures for the physical installation. This includes:

   • Unpacking and inspecting the module, emphasizing the crucial need for antistatic precautions.
   • Instructions for system software backup and shutdown (a customer responsibility).
   • Configuring the M8087 module by setting various jumpers (both factory preset and user-selectable for device address, DMA, etc.).
   • Guidance on relocating existing modules within the BA213 enclosure if needed.
   • Detailed steps for installing the M8087 module into the backplane.
   • Procedures for verifying ground connections using gap fillers to meet FCC regulations.
   • Connecting external devices: laser printers to J1 (BC27P-15 cable) and scanners to J2 (BC27N-15 cable).

3. Chapter 3: MicroVAX Diagnostics Monitor describes how to use the MicroVAX Diagnostic Monitor (MDM), a software tool for testing and troubleshooting the system. It explains how to run MDM tests (specifically "Test the System" for general checks and "Select Single Device Tests" for individual components like the LNV21-SF Controller) to ensure the system and the newly installed module are operating correctly before and after installation.

Throughout the document, "CAUTION" notes frequently highlight the importance of safety measures, particularly antistatic precautions, to prevent damage to sensitive electronic components.
