Preface

Overview

This manual describes how to install the SmartSwitch Router 510 and SmartSwitch
Router 520 (also referred to in this manual as SSR-510 and SSR-520). It also provides
problem solving information, connector pin assignments, and other general information.

Using This Guide

Read through this guide completely to understand the router features, capabilities, and
Local Management functions. A general working knowledge of Ethernet and IEEE 802.3
type data communications networks and their physical layer components is helpful when
using these devices.

Intended Audience

This manual is intended for the hardware installer. The installer is responsible for ensuring
that the h ardware is installed and teste d. It shows how to inst all when th e site is ve rified
and the cables and devices are in place. This guide shows how to verify the site, install
cables and devices and troubleshoot problems. The person installing software can then
verify the system inst allation.

Product Introduction

What Are the SmartSwitch Router 510 and
SmartSwitch Router 520?

The SmartSwitch Router SSR-510 and SmartSwitch Router SSR-520 (also
referred to in this manual as the SSR-510 and SSR-520 routers) provide
multiprotocol rou ting for linking Ethernet LANs to corporate Wide Area
Networks (WAN).

The routers off er fle xi ble sof twa re s uppo rt tha t ca n be tai lo re d to t he n eeds of
specific remote environments.

The SSR-510 and SSR-520 router s are available wi th Multiprotocol Sof tware.
Protocol support, for your package, is described in the Cabletron Distributed
Routing Software Release Notes.

The SSR-510 and SSR-520 standards-compliant technology ensures
interoperability in multivendor networks.

SSR-510 Router

The SSR-510 router has the following port connections:

• One Ethernet interface, in either dedicated Ethernet (10Base2) or twisted
pair (10BaseT)

• One synchronous serial WAN port capable of T1/EI data rates

• One ISDN basic rate interface (BRI) S/T-interfa ce

SSR-520 Router

The SSR-520 router has the following port connections:

• One Ethernet interface, in either dedicated Ethernet (10Base2) or twisted
pair (10BaseT)

• Two synchronous WAN ports capable of T1/EI rates

1-2

Features

The SSR-510 and SSR-520 routers include the following features.

Performance and Memory

The SSR-510 and SSR-520 routers conta in the followin g performance and
memory features:

• Industry-standard processors operating at 22.5 MHz clock rates, and
utilizes 32-bit address and data buses for maximum bus bandwidth.

• 4 MB of system flash memory.

• 4 MB of system memory using PC compatible memory DSIMMS.

• Memory accesses are parity protected on a byte wide basis.

Product Introduction

Configuration and Management

The following configuration and management options are available:

• Support for the following configuration options:

–– EasyStart configuration loader
–– Graphical User Interface (GUI) using the clearVISN Router

Configurator tool

–– Command Line Interface (CLI) using the console port
–– CLI using Telnet

• Upgradeable device firmware (in nonvolatile Flash memory) using
Trivial File Transfer Protocol (TFTP).

• Simple Network Management Protocol (SNMP) for monitoring.

1-3

Product Introduction

EasyStart

EasyStart is a featur e that allo ws you to downlin e load configur ation files
that are stored on a server via BOOTP/TFTP.

Using EasyStart and t he clearVISN Router Configurator eliminates the
need for configuring the router using the Command Line Interface (CLI).
When the router is booted, it autoconfigures all interfaces and sends out
requests to load its configuration file. Once the file is received, the router
automatically r estart s so that the confi guratio n paramet ers spec ified i n the
file take effect.

Refer to the SmartSwitch Router 500 Series System Software Guide for
information about using the EasyStart feature.
