Digital GIGAswitch GS2000 Line Card Installation DEFGC-AA

This document provides critical installation and testing information for the DIGITAL GIGAswitch GS2000 (GS2000) line card (DEFGC-AA), designed for various GIGAswitch/ATM and GIGAswitch/FDDI systems.

The GS2000 module features one ATM port supporting modular PHY (modPHY) cards and one FDDI Dual Attachment Station (DAS) port using two FDDI modular Physical layer Media Dependent (modPMD) cards. The document lists the specific STS-3c ATM modPHY and FDDI modPMD cards supported.

It outlines the minimum firmware requirements for both GIGAswitch/ATM (V2.5, CMM V1.90) and GIGAswitch/FDDI (SCP V3.3, CLK V3.3) systems, noting that GIGAswitch/ATM V2.5 requires an expanded memory option. It also provides URLs for obtaining updated software images.

Installation instructions refer to the system's Installation and Service manual for general procedures but emphasize the necessity of installing the appropriate DC-to-DC power module (48V or 5V options) before inserting the line card. The document details the steps for correctly installing and carefully removing these power modules.

A significant portion of the document is dedicated to "Testing the Line Card," explaining how to interpret the module's self-test (MST) results via various Light-Emitting Diodes (LEDs). Detailed tables describe the meaning of LED conditions for module status, Load/Dump/Management (LDM) port status and activity, general port status (FDDI and ATM), and specific PHY LEDs for both FDDI modPMD and ATM modPHY cards, indicating link status, errors, faults, and operational states.
