DEC LANcontroller 200 Installation Guide

This document is the DEC LANcontroller 200 Installation Guide, also referred to as the DEBNI controller.

Purpose:

• It provides instructions for installing the DEC LANcontroller 200 adapter, which is an Ethernet/IEEE 802 controller designed to interface local area networks with VAXBI bus systems.
• The guide also details the adapter's self-test procedures and offers troubleshooting advice.
• It is intended for use by DIGITAL customer service representatives and self-maintenance customers.

Key Content Areas:

• Introduction: Describes the DEBNI's basic functions, its onboard MicroVAX processor for independent operations, and its diagnostic capabilities. It notes that the DEBNI can be an upgrade from the older DEBNA controller.
• Installation: Offers step-by-step instructions for physically installing the module into a VAXBI computer system, covering power-down procedures, ESD precautions, cabling (internal Ethernet and power), and placement of the firmware console-enable jumper.
• Installation Verification & Troubleshooting: Guides users on how to verify successful installation by checking LED indicators and self-test results. It provides detailed troubleshooting steps to identify faulty components (e.g., transceiver, cables, DEBNI module, backplane) if self-tests or network communication fail.
• Power-Up Self-Test: Explains the ROM-resident diagnostic routines that run automatically on power-up or reset, how to run them from the console, and how to interpret their results via status LEDs and the Power-Up Diagnostic (XPUD) Register. It also lists the components and functions tested/untested.
• Appendices: Provide supplementary information on environmental requirements, descriptions of relevant DEBNI registers for troubleshooting, procedures for bootstrapping (network booting), methods for reading the DEBNI's hardware Ethernet address on different VAX systems, and instructions for upgrading a DEBNA module to a DEBNI.
