GIGAswitch/ATM 5-Slot System Installation and Service

This document serves as a comprehensive guide for the installation and servicing of the GIGAswitch/ATM 5-slot system, an intelligent ATM switching system providing 3.2 Gb/s performance. It is intended for experienced network hardware personnel.

The guide covers:

• System Overview: A description of the GIGAswitch/ATM 5-slot system components, including its clock card, fan tray, and power tray, noting its power supply redundancy and limited hotswap capabilities.
• Installation Procedures: Detailed steps for site preparation, unpacking, initial module self-tests, preparing and mounting the system in a rack, and setting up electrostatic discharge (ESD) protection.
• Configuration: Instructions for setting up hardware for asynchronous, Ethernet, and SLIP access, configuring BootP and TFTP servers for firmware updates, and initiating out-of-band management (OBM) sessions.
• CMM Commands: Explanation of Clock Management Module (CMM) local mode commands for various tasks, such as displaying system configurations, retrieving error logs, and modifying switch settings.
• System Testing: Guidance on initiating and evaluating module self-tests (MSTs) and interpreting LED indications on different modules for diagnostic purposes.
• Firmware Upgrades: Procedures for copying and loading new firmware versions for both line cards and the CMM, often involving TFTP/BootP servers.
• Module Replacement: Instructions for replacing field-replaceable units (FRUs), including logic modules (line cards, clock card), blank handles, fan tray, and power tray assemblies, emphasizing ESD precautions and power removal.
• System Removal: Steps to safely detach and remove the GIGAswitch/ATM system from its rack.
• Backplane Replacement: A procedure for replacing the system's backplane assembly, highlighting its complexity.
• Appendices: Provide detailed physical, electrical, and environmental specifications, along with descriptions of cooling, power, and logic modules, and guidelines for module placement.
