DECrepeater 900FP Installation and Configuration

This document provides comprehensive instructions for the installation and configuration of the PORTswitch 900FP module, a 12-port, 10BaseFL, fiber-optic Ethernet repeater.

Key aspects covered include:

• Product Overview: Describes the PORTswitch 900FP's capabilities, its deployment options within a DEChub 900 MultiSwitch or as a standalone unit with a DEChub ONE docking station, and its hot-swap feature. It highlights core features such as SNMP management (in-band and out-of-band), firmware upgradeability via TFTP, and port-level security.
• Hardware Description: Details the functions of the front panel LEDs (Power, Module OK, Network OK, Network Activity, Port State, Port Link) for status indication and the components of the back panel (locking tab, connectors, labels).
• Installation and Removal: Provides step-by-step guidance for physically installing and removing the module, including power considerations and the process for connecting fiber-optic cables (ST-type connectors).
• Configuration: Explains how to access the module's setup port (via DEChub 900 or DEChub ONE) and navigate its menu-driven interface. It details various configuration options, such as resetting to factory defaults, viewing current settings, managing SNMP parameters (read/write community, trap addresses), setting IP addresses (in-band and out-of-band), and performing downline firmware upgrades. Critical safety warnings regarding power interruption during firmware upgrades are emphasized.
• Redundant Fiber-Optic Link Configuration: A significant section dedicated to setting up redundant fiber-optic links for failover. It defines key concepts like master and responder ports, primary and secondary links, and the differences between partial and full fault detection. Recommendations for optimal redundancy and reliability are provided.
• Troubleshooting: Utilizes LED states to diagnose common issues encountered during initial installation and operation, offering probable causes and corrective actions.
• Technical Specifications: Includes detailed fiber-optic loss budget calculations for 10BaseFL and FOIRL compatibility, connector pin assignments, and general product specifications covering operating environment, physical dimensions, power requirements, and certifications.

The document consistently includes important safety warnings, particularly concerning laser/infrared light emitted by fiber optics and the risks of interrupting power during critical operations like firmware upgrades.
