DECswitch 900ET

This document serves as a comprehensive guide for the DECswitch 900ET module, a bridging router designed to interconnect Token-Ring and Ethernet LANs. It details the module's installation, configuration, and removal within two primary environments: a DEChub 900 MultiSwitch or as a standalone unit in a DEChub ONE docking station.

Key areas covered include:

• Product Introduction: An overview of the DECswitch 900ET, highlighting features like hot-swap capability, support for various routing protocols (IP, IPX, AppleTalk, DECnet, OSPF, RIP, EGP, IS-IS, MOSPF, DVMRP), and bridging options (ASRT, Spanning Tree, Source Routing). It also describes front and back panel components and their functions.
• Installation: Step-by-step instructions for installing the module into a DEChub 900, including power rating checks, physical seating of the module, verification of LED operation, and connecting Token Ring (9-pin and UTP) and Ethernet (AUI and 10BaseT) cables.
• Configuration: Detailed procedures for setting up and configuring the module's software via a setup port. This involves using menu-driven interfaces or command-line commands (Telnet) to assign IP addresses, subnet masks, default gateways, configure Out-of-Band Management (OBM) port speed and RTS settings, and define Token-Ring and Ethernet port connections, with specific instructions for both DEChub ONE and DEChub 900 environments.
• Removal: Guidance on safely disconnecting cables and unseating the module from a DEChub 900.
• Appendices: Troubleshooting information using LED indicators, detailed connector and pin assignments for various cable types, and comprehensive product specifications covering operating environment, physical dimensions, acoustical data, and regulatory certifications.
