DIGITAL VNswitch 900XA

This manual, published in August 1997, provides instructions for installing and configuring the DIGITAL VNswitch 900XA module. It also covers the installation of ATM Modular PHY (modPHY) cards and 100 Mb/s Fast Ethernet Modular Media Interface (MM-100) cards. The document is intended for personnel responsible for setting up the VNswitch 900XA.

Key areas covered include:

• Product Introduction: Describes the VNswitch 900XA as a high-throughput, SNMP-manageable, multiport network switch for linking Fast Ethernet and ATM networks, transparently converting MAC frames to ATM cells and vice versa. It supports hot-swappable MM-100 and ATM modPHY cards, auto-configures to a 400 Mb/s VNbus, and offers extensive filtering capabilities for network control and security. Features include bridging (high-speed filtering, full line-rate forwarding, spanning tree protocol), Ethernet (half- and full-duplex operation), and ATM capabilities (155 Mb/s ports, LAN Emulation clients, virtual ports, flow control, Virtual Circuits, Virtual Paths). It also details SNMP support and VLAN Secure Domain (VSD) features for grouping ports and managing multicast domains.
• Installation: Guides users through installing modular media interface cards into the VNswitch 900XA, and then installing the VNswitch 900XA module itself into a DIGITAL MultiSwitch 900 or a DEChub ONE/ONE-MX docking station. This includes preparing for installation, seating the module, and verifying initial LED operations.
• Configuration: Provides instructions for connecting and configuring the module via a setup port cable using menus in either a DEChub ONE docking station or a DIGITAL MultiSwitch 900 chassis. Configuration options include assigning IP addresses (in-band and out-of-band), setting SNMP read/write communities, default gateways, and accessing a local console or product-specific options (like viewing/clearing error logs, and enabling/disabling Automatic VNbus Connection).
• Removal: Details the steps for safely removing the module and its associated cables.
• Problem Solving: Offers guidance on diagnosing issues using the module's LED indicators, listing common symptoms, probable causes, and corrective actions.
• Connectors and Specifications: Provides detailed information on various connectors and adapters used with the VNswitch 900XA, including pin assignments, along with product and acoustical specifications (environmental, physical, power, shock, vibration, certification).
