Introduction

1-2 Using the STS16-20 User’s Guide

The STS16-20RM and STS16-20FRM provide two slots for optional expansion
SmartSTACK Interface Modules (SSIMs). Several types of SSIMs are available
which provide either standard 4/16 Mbps Token Ring connectivity, or high speed
connectivity via 155 Mbps ATM, 100 Mbps High-Speed Token Ring, and 100
Mbps Fast Ethernet, as described below:
¥ The Token Ring SSIMs (T5-04 and T8-04) provide 4 additional 4/16 Mbps ports
of Token Ring connectivity via twisted-pair with RJ-45-type connectors or
multimode Þber with ST-type connectors.
¥ The ATM SSIMs (A2-01 and A8-01) provide 1 port of 155 Mbps high-speed
connectivity to an ATM backbone via twisted pair with RJ-45-type connectors
or multimode Þber with duplex SC-type connectors.
¥ The HSTR SSIMs (R2-02 and R8-02) provide 2 ports of 100 Mbps High-Speed
Token Ring connectivity via twisted pair with RJ-45-type connectors or
multimode Þber and VF-45-type connectors. The HSTR SSIMs integrate Token
Ring networks with High-Speed Token Ring servers or backbones.
¥ The Fast Ethernet SSIM (H2-02) is a translational switch that provides 2 ports
of 10/100 Mbps Fast Ethernet connectivity via twisted pair with RJ-45-type
connectors. The Fast Ethernet SSIM integrates Token Ring and Ethernet
networks.
Using the STS16-20 User’s Guide
Each chapter in this guide describes one major functionality or a collection of
several smaller functionalities of the STS16-20, which are accessed directly from
the device icon. Additional management information about tools and features
common to many devices can also be found in the
NetSight Element Manager
UserÕs Guide
, the
NetSight Element Manager Tools Guide
, and the
Remote
Administration Tools UserÕs Guide
.
Because the SmartSTACK Token Ring switches ÑSTS16-20RM, STS16-20FRM,
STS16-20D, and STS16-20RÑ share much of their functionality, the devices will be
jointly referred to as the STS16-20 throughout this guide. The options available
and the information displayed in some of the windows may differ slightly,
depending on the type of STS16-20 device being managed.
The following is a description of the chapters contained in this guide. While we
provide as much background information as we can, we do assume that you are
familiar with Token Ring networks and general network management concepts.
NOTE
Depending on the type of SSIMs installed in the STS16-20FRM and STS16-20RM,
the management options available will vary. If you have an ATM SSIM (A2-01 and
A8-01) installed, the ATM Connections option will be available from the Device menu.
