Introduction

The 9T125-24 Module MicroLAN™ Switch Module, shown in Figure , is a

three-port Token Ring switch module. This module supports two separate front

panel Token Rings with twelve HUB connections, and an interface to the FNB

backplane.

Features

Processor

The 9T125-24 Module is equipped with an advanced Intel i960 microprocessor.

This microprocessor provides a platform for all management functions within a

scalable RISC-based architecture.

System Management

Interfaces to the two System Management Buses (SMB-1 and SMB-10) for

intermodule management.

Connectivity

The 9T125-24 provides twenty four RJ45 Trunk Coupling Unit (TCU) lobe

connectors.

SRT Packet Switching

SRT Bridging occurs between the front panel Token Ring connections and SR-TB

bridging to any other module in the chassis via FNB -1 or FNB -2 of the FNB bus.

The module is capable of Transparent Bridging and/or Source Route Bridging.

IEEE 802.1d Spanning Tree Protocol is supported in all bridging functions.

Translational bridging between Source Routing and Transparent Frames types is

also performed for packets destined for the FNB.
