KLESI-SF Q22-bus Adapter Option Installation Guide

This document is the "KLESI-SF Q22-bus Adapter Option Installation Guide" (Order No. EK-KLESI-IN-001) published by Digital Equipment Corporation in December 1987.

The guide provides step-by-step instructions for installing the KLESI-SF Q22-bus adapter option kit into BA200 series microsystem enclosures. The KLESI module serves as a controller for Mass Storage Control Protocol (MSCP) devices, such as the TU81E tape drive. It is intended for Digital Field Service personnel or qualified self-maintenance customers.

The installation process is divided into three main chapters:

1. Description: Introduces the BA200 series enclosures (6- or 12-slot Q-bus backplane) and details the function of the KLESI-S (M7740-00) Q22-bus adapter module as an MSCP controller for devices like the TU81E tape drive in systems such as the MicroVAX 3600.
2. Installation: Provides comprehensive instructions covering:
   • Pre-installation steps for the TU81E tape transport.
   • Unpacking and inspecting the KLESI-SF option kit, including EMI and EOS clips.
   • Crucially, emphasizes software backup and operating system shutdown before proceeding.
   • Guidelines for checking system configuration, including power and bus load data, and rules for module placement (e.g., bus continuity, recommended order).
   • Configuring the KLESI-S module's control and status register (CSR) address using DIP switches.
   • Procedures for testing the existing system, relocating other modules if necessary, and finally installing the KLESI-S module.
   • Instructions for verifying ground connections and attaching gap filler assemblies for EMI compliance.
   • Steps for connecting the KLESI-S controller module to the TU81E tape transport.
3. Testing the New Configuration: Details how to test the newly installed hardware on both MicroVAX and MicroPDP-11 systems using diagnostic monitors (MDM or XXDP+), ensuring the new module and tape drive are recognized and function correctly. It concludes with steps for reconnecting external devices and bringing the operating system back online.

Throughout the guide, cautions are provided regarding static discharge prevention and maintaining proper bus grant continuity.
