DELQA-SF Q-bus to Ethernet Adapter Option Installation Guide

This document is the DELQA-SF Q-bus to Ethernet Adapter Option Installation Guide (Order No. EK-DELQA-IN-001), published in December 1987 by Digital Equipment Corporation.

It provides step-by-step instructions for installing the DELQA-SF module (M7516), which is a quad-height Q-bus to Ethernet adapter, into BA200 series microsystem enclosures. The DELQA module facilitates a high-speed asynchronous connection between a Q-bus system and a Local Area Network (LAN) based on Ethernet, supporting both DEQNA and enhanced DELQA modes with Maintenance Operation Protocol (MOP) functions.

The guide is intended for Digital Field Service personnel and qualified self-maintenance customers. It covers:

• Pre-installation procedures: Unpacking, inspecting EMI and EOS clips, performing software backups, and checking system configuration (including power and bus load data, module placement guidelines, and determining CSR addresses and interrupt vectors using SYSGEN).
• Physical Installation: Detailed steps for relocating existing modules and installing the DELQA module, emphasizing antistatic precautions and proper ground connections using gap filler assemblies.
• Module Configuration: Instructions for setting the DELQA module's switches for various modes and options (e.g., CSR address, DEQNA/DELQA mode, remote boot, sanity timer).
• Post-installation Testing: Procedures for verifying the new configuration, including checking LED test patterns, running diagnostics on MicroVAX (MDM) or MicroPDP-11 (XXDP+) systems, reconnecting external devices, connecting the DELQA module to the network, and performing additional network tests using NIE and NCP tools.
