DIGITAL GIGAswitch/Ethernet System Installing Fast Ethernet Modules

This document provides installation and configuration instructions for Fast Ethernet I/O modules within the DIGITAL GIGAswitch/Ethernet System. It specifically covers the 20-Port 10/100BASE-TX Ethernet Module (RJ45) and the 10-Port 100BASE-FX Ethernet Module (Fiber).

The installation procedure outlines four main steps:

1. Power Availability Check: Ensure enough power is available, noting that the 20-port module uses 70W and the 10-port module uses 50W. Power status can be checked via the Web Agent.
2. Module Installation: Modules are hot-swappable. Users are cautioned to observe antistatic precautions when handling and installing them into the switch chassis, locking them with ejectors, and tightening screws. LED indicators are described for normal operation.
3. Cable Installation: Instructions for connecting fiber (SC-type) and copper (RJ45 straight-through for end stations, crossover for switch-to-switch) cables are provided, along with maximum link distances (e.g., 2 km for fiber full-duplex, 100 m for copper Category 5).
4. Port Parameter Configuration: This is done via the Web Agent. Users can configure settings such as enabling/disabling ports, assigning names, manually setting speed (10/100 Mb/s) and duplex mode (half/full), enabling flow control (IEEE 802.3x pause control for full-duplex, active backpressure for half-duplex), setting auto-negotiation modes and advertisement options, and configuring rate limits for flooded packets. The document also describes how to apply settings to all ports on a module simultaneously.
