DECswitch 900FO

This document is a comprehensive guide for the installation and configuration of the DECswitch 900FO module. It details how to set up and manage this self-learning IEEE 802.1d Media Access Control (MAC) switch, which interconnects six 10BaseFL 10 Mb/s Ethernet LANs with a high-speed 100 Mb/s Fiber Distributed Data Interface (FDDI) network backbone.

Key aspects covered include:

• Installation: Instructions for installing the DECswitch 900FO into a DEChub 900 MultiSwitch or a standalone DEChub ONE/ONE-MX docking station, including power rating comparisons, module seating, LED verification, and port cable connections.
• Configuration: Detailed procedures for configuring the module via a set-up port using menus. This includes setting IP addresses, SNMP read/write communities, SNMP trap addresses, enabling/disabling BootP, and performing downline firmware upgrades. It also covers module-specific options like FDDI and Ethernet configurations, and IPX switch settings.
• Features: An overview of the module's capabilities, such as hot swap, protocol independence, flexible filtering, out-of-band management (OBM) over Serial Line Internet Protocol (SLIP), advanced GUI manageability with clearVISN MultiChassis Manager, and support for Simple Network Management Protocol (SNMP) and Remote MONitoring (RMON) groups (Statistics, History, Alarms, Events, and optional enhanced groups). It highlights Virtual LAN (VLAN) support for network segmentation and security, and bridging options including spanning tree protocols.
• Technical Information: Appendices provide essential data on problem solving using LED displays, fiber-optic loss budgets (10BaseFL and FOIRL compatibility), product specifications (operating, acoustical, connectors), and descriptions of network cables.
