You cannot use the USB and RS232 console ports at the same time; if you insert the USB cable into the

router, the RS232 port is disabled.

Connecting to the Serial Port using Microsoft Windows

This procedure shows how to connect to the serial port using Microsoft Windows.

Note

Install the USB device driver before establishing a physical connection between the router and the PC,

by using the USB Console cable plugged into the USB serial port. Otherwise, the connection will fail.

For more information, see the Installing the Cisco Microsoft Windows USB Device Driver section in the

Cisco ASR 903 and ASR 903U Aggregation Services Router Hardware Installation Guide.

Procedure

Step 1

Connect the end of the console cable with the RJ45 connector to the light blue console port on the router. or Connect a

USB Type A-to-Type A cable to the USB console port as shown in the figure below . If you are using the USB serial port

for the first time on a Windows-based PC, install the USB driver now according to the instructions in the following sections.

You cannot use the USB port and the EIA port concurrently. See the Connecting to the Auxiliary Port section in

Note

the Cisco ASR 903 and ASR 903U Aggregation Services Router Hardware Installation Guide. When the USB

port is used it takes priority over the RJ45 EIA port.

The USB Type A-to-Type A cable is not included with the Cisco ASR 903 Router; it is ordered separately.

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.

software should be configured with the following parameters:

• 9600 baud

• 8 data bits
