About This Guide

This section discusses the objectives, audience, organization, and conventions of this

hardware installation and conﬁguration guide.

Objectives

This publication will step you through the initial site preparation and installation of the

router. Troubleshooting, maintenance procedures, and cable speciﬁcations are also

provided.

Although minimum software conﬁguration information is provided, it is not meant as

comprehensive router conﬁguration instructions. For detailed software conﬁguration

information, refer to the Cisco IOS conﬁguration guide and command reference

publications. These publications are available on the documentation CD that came with

your router or you can order printed copies. Refer to the “Ordering Documentation” section

in the “Overview of the Router” chapter for ordering information.

This publication describes a variety of router models that are similar in functionality, but

differ in the number of interfaces supported. Some information provided may not apply to

your particular router model.

AudienceThispublicationisdesignedforthepersoninstallingtherouter,whoshouldbefamiliarwith

electronic circuitry and wiring practices and have experience as an electronic or

electromechanical technician.

xvi Router Installation and Configuration Guide

Organization

The major sections of this hardware installation and conﬁguration guide are as follows:

•Chapter 1, “Overview of the Router,” discusses the features and speciﬁcations of the

routers, and describes how to obtain technical support and order documentation.

•Chapter 2, “Preparing to Install the Router,” discusses environmental requirements,

safety recommendations, and describes the various ports and how to prepare for

connections between networks and ports.

•Chapter 3, “Installing the Router,” includes basic installation information and discusses

making connections to your LAN, WAN, and console terminal.

•Chapter 4, “Conﬁguring the Router,” discusses how to conﬁgure your router using the

prompt-driven System Conﬁguration Dialog, conﬁguration mode, or AutoInstall. This

chapter also provides some basic information about how to use the Cisco IOS software.

•Appendix A, “Troubleshooting the Router,” discusses how to isolate problems and read

the LEDs.

•Appendix B, “Maintaining the Router,” discusses selected maintenance procedures.

•Appendix C, “Cable Speciﬁcations,” provides pinouts for the router ports and cables.

Overview of the Router 1-1

Overview of the Router

Table 1-1 lists the router models discussed in this publication and provides a summary of

the interfaces supported on each model. These router models are similar in functionality,

but differ in the number of interfaces supported.

1. AUI = attachment unit interface.

2. ISDN = Integrated Services Digital Network.

3. BRI = Basic Rate Interface.

4. A CPA2515 model is not available.

Hardware Features

Note Throughout the remainder of the publication, one model number will be used in text

references. For example, references to the model 2501 router will apply to both the

Cisco 2501 and CPA2501 routers.

Hardware Features

In addition to the interfaces listed in Table 1-1, the routers include the following hardware

features:

•Dynamic random-access memory (DRAM) for main memory and shared memory

•Nonvolatile random-access memory (NVRAM) for storing conﬁguration information

•Flash memory for running the Cisco IOS software

•EIA/TIA-232 console port for local system access using a console terminal

•EIA/TIA-232 auxiliary port for remote system access using a modem

Note EIA/TIA-232 and EIA/TIA-449 were known as recommended standards RS-232

and RS-449 before their acceptance as standards by the Electronic Industries Association

(EIA) and Telecommunications Industry Association (TIA).
