SmartStack STS-8SU & STS-SM Installation and User Guide Overview and Specifications

1. Overview and Specifications

This chapter provides an overview of the SmartStack STS-8SU External Stacker

Unit and related Cabletron equipment. You will also find a list of specifications for

the STS-8SU External Stacker Unit.

Overview

To take full advantage of the network switching architecture, the switched network

must be scalable. In a scalable network you can increase the number of switch ports

on demand. Moreover, each switch must be extendable through the backplane in

order to maintain the high aggregate bandwidth between all switch ports. Switches

meeting these demands are stackable switches.

The stackable network equipment in the Cabletron product family provides the

basis for flexible and scalable network solutions. The Cabletron products include

equipment for stacking two to eight switches, as well as a wide range of expansion

modules that provide extra ports or attachments to existing networking equipment.

This guide describes how to install and use the STS-8SU External Stacker Unit, a

dedicated switch stacker unit that allows you to connect up to eight switches. Also

described is the SmartStack STS-SM Switch Matrix, that can be installed in the

STS-8SU Stacker to providing increased network reliability.
