DIGITAL VNswitch 900FA

This document is a comprehensive manual for the DIGITAL VNswitch 900FA module, detailing its installation, configuration, and maintenance. The VNswitch 900FA is a high-throughput, SNMP-manageable multiport network switch designed to link Fiber Distributed Data Interface (FDDI) and Asynchronous Transfer Mode (ATM) networks, facilitating transparent conversion between FDDI frames and ATM cells.

The manual provides step-by-step instructions for:

• Installing and removing modular media interface cards (Mod-FDDI and modPHY cards).
• Installing and removing the VNswitch 900FA module into a DIGITAL MultiSwitch 900 chassis or a DEChub ONE/ONE-MX docking station.
• Connecting the setup port cable for initial access and parameter configuration.

Key features of the VNswitch 900FA highlighted include hot-swapping capabilities for modules and interface cards, diverse configuration and management options via SNMP or Command Line Interface (CLI), high-performance bridging (including IEEE 802.1d Spanning Tree Protocol compliance), and extensive support for ATM (e.g., LANE Clients, Virtual Circuits, Virtual Paths) and FDDI (full-duplex, tree/dual-ring configurations, concentrator attachment). It also supports various SNMP MIBs and VLAN Secure Domains for network segmentation and management.

Additionally, the document includes sections on troubleshooting using LED indicators, details on connectors and adapters with pin assignments, and comprehensive product specifications covering environmental, physical, power, and acoustical characteristics.
