•Install cable ties in accordance with your site requirements.

For cable pinouts, refer to the online document Cisco Modular Access Router Cable Specifications .

Connecting to a Console Terminal or Modem

Your router has asynchronous serial, USB, console and auxiliary ports. These ports provide administrative access to your router either locally (with a console terminal or PC) or remotely (with a modem).

The following cables and adapters may be used for connecting your router to a console terminal, PC, or modem:

•USB Console cable—USB 5-pin mini Type-B to USB Type-A. See «USB Serial Console» section for port details and «Specifications» section.

•Console cable— EIA RJ-45 to DB-9

•Modem adapter—DB-9 to DB-25

Note The first time a Windows based PC is connected to the router, a USB device driver must be installed. See Installing the Cisco Microsoft Windows USB Device Driver.

This section describes how to connect a console terminal or PC to the console port and how to connect a modem to the auxiliary port.

Connecting to the Console Port with Microsoft Windows

To configure the router through the Cisco IOS command-line interface (CLI), you must connect the router console port to a terminal or PC. See «Console and Auxiliary Port Considerations» section.

A Microsoft Windows PC must have HyperTerminal or similar terminal emulation software installed. The software should be configured with the following parameters: 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control. Refer to the Cisco 3900 Series, 2900 Series, and 1900 Series Software Configuration Guide for detailed information about using Cisco IOS software for configuring the router.

To connect the router to a terminal or PC, follow these steps:

Step 1 Connect the end of the console cable with the RJ-45 connector to the light blue console port on the router, or USB 5-pin mini Type-B to the USB console port as shown in Figure 5-1. If connecting the USB port for the first time on a Windows based PC, you must install the Windows USB driver. See «Installing the Cisco Microsoft Windows USB Device Driver» section.

Note You must use either the USB port or the RJ-45 port. Not both simultaneously. See «USB Serial Console» section. When the USB port is used it takes priority over the RJ-45 EIA port.

3	USB Type-A connector

Step 2 Connect the end of the cable with the DB-9 connector (or USB Type-A) to the terminal or PC. If your terminal or PC has a console port that does not accommodate a DB-9 connector, you must provide an appropriate adapter for that port.

Step 3 To communicate with the router, start a terminal emulator application.
