Introduction

This document describes the pinouts used for making a management cable for the Cisco 600 series Customer Premises Equipment (CPE). The cable allows the user to manage and configure the Cisco 600 from a Windows PC running HyperTerminal. This document specifically covers PCs that have a communications port (COM port) with a DB-9 serial port connector and the Cisco 600 CPE, which has an RJ-45 serial port.

Prerequisites

There are no specific prerequisites for this document.

Components Used

The information in this document is based on the hardware versions below.

• RJ-45 male connector

• High quality cable, such as category 5

• DB-9 female connector

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.

Background Theory

The following is a typical management cable shipped with the Cisco 600 CPE.

Making a Management Cable

Using the required connectors and cable, build a management cable using the following diagram as a guide.

Using a Management Cable

Step-by-Step Instructions

When you finish building the management cable, follow the steps below to properly use it.

1. Connect the cable's DB-9 female connector to the DB-9 (male) serial COM port of your PC.

2. Connect the cable's RJ-45 male connector to the management port (labeled "MGMT") of your Cisco 600 CPE.

   

3. Configure your terminal access program (such as HyperTerminal in Windows) with the following settings:

   • COM port: Port into which you plug the cable.

   • Baud rate: 38400 bps - recommended (standard 9600 bps possible)

   • Data bits: 8

   • Parity: None

   • Stop bits: 1

   • Flow control: None

4. Press Enter until you see the prompt (such as cbos>, modem1> or usa>). When you see the prompt, the PC and CPE are communicating.

Note: If the computer has only a DB-25 serial port, a DB-9 to DB-25 adapter is also needed. Also, the same cable can be used to connect a dumb terminal to the Cisco 600 management port.
