ATMworks 750 Installation and Service

This document provides comprehensive instructions for the installation and verification of the ATMworks 750 adapter card in Alpha AXP systems, specifically DEC 3000 series workstations. The ATMworks 750 is described as a single-slot, dual-height option card enabling Asynchronous Transfer Mode (ATM) network connectivity. It utilizes 155 Mbps multimode fiber optic cabling and supports key ATM features such as Adaptation Layer 5 (AAL5), full-duplex operation, FLOWmaster™ flow control, 2048 virtual channels, and quality of service (CBR, ABR). The card uses a packet-based interface to eliminate host processing of ATM cells and supports various ATM protocols including Classical IP over ATM, PVCs, SVCs, and LAN emulation.

The manual outlines hardware and power requirements for the adapter. The installation process involves preparing the system (shutdown, disconnecting cables, removing covers), using essential tools like a Phillips screwdriver and an anti-static grounding strap, physically inserting the adapter card into an available TURBOchannel slot, securing it, and connecting the SC-type multimode fiber optic cables. Throughout the installation, critical safety warnings regarding static electricity and potential eye injury from laser light in fiber optic equipment are emphasized.

Following installation, the document details how to test and verify the adapter's functionality through an automatic power-up self-test and by checking LED indicators (MOD and PHY LEDs) and system configuration displays. It provides specific console commands to verify the adapter's recognition and offers troubleshooting steps for common issues, such as incorrect seating, cable connections, or software configuration problems, before guiding the user to boot the operating system.
