Introduction

The 9E132-15, 9E133-36, 9E138-12, and 9E138-36 MicroLAN™ Switch Modules, shown in Figure 1-1, are four channel Ethernet bridges and routers. Up to three front panel Ethernet networks can be connected to this module and they can be bridged/routed to any other Ethernet segment and to any other SmartSwitch 9000 module via the FNB bus (acting as the fourth port).

Features

NOTE

The 9E132-15, 9E133-36, 9E138-12, and 9E138-36 MicroLAN™ Modules will be referred to collectively as the Ethernet MicroLan Modules.

Processor

The Ethernet MicroLan Switch Modules are equipped with an advanced Intel i960 microprocessor. This microprocessor provides a platform for all management functions within a scalable RISC-based architecture.

System Management

The Ethernet MicroLan Switch Modules provide interfaces to the two System Management Buses (SMB-1 and SMB-10) for intermodule management.

Connectivity

The 9E132-15 provides four RJ-45 ports and one EPIM slot for each of the three channels. See Chapter 5 for information on the use of EPIMs.

The 9E133-36 has one 50-pin front panel for each of the three channels, providing 12 individual Ethernet connections each.

The 9E138-12 provides four ST-type multi-mode fiber optic connections for each of the three channels, for a total of 12 connections.
